SECTION IINTRODUCTION

Sensor

The heart of the PA/PG3000 transmitter is asputtered strain gage sensor that converts amechanical force (pressure) to an electricalsignal. A wheatstone resistance bridge circuit ismolecularly deposited on a metal bending beamusing a technique similar to the process used tomanufacture high density integrated circuit chips.The deposition process is carried out in a Class100 clean room under direct computer control toensure conformance to Ametek Gulton-Stathams specification. Each finished beam istested for linearity, sensitivity, thermal stability,

bridge resistance and balance prior toassembling the sensor. The sensing mechanismis isolated from the process fluid by an isolationdiaphragm and silicone fill fluid.

AmplifierThe simple DC measurement provides excitationvoltage to the wheatstone bridge, converts the

bridge output to a current (mA) signal andprovides electrical offset of zero to simulate (0)psi. The amplifier is packaged in a hermeticallysealed CRES 316 steel housing to guard againstmoisture and corrosion, the leading cause ofelectronic component failure in competitivetransmitters. AMETEK Gulton-Statham utilizeshigh energy product magnets to couple theinternal potentiometers to the externaladjustment screws. As the outside magnet isturned the internal magnet also sums, adjustingthe zero and span potentiometers. After

calibration is completed, the external magnetsmay be removed and keepers inserted toprovide tamper-proof installation

Figure 1.2 - Amplifier Block Diagram

In Process VerificationThe transmitters are tested for accuracy, stabilityand reliability during each manufacturing phase.Sensing assemblies are checked in anenvironmental chamber to verify performancecharacteristics and eliminate mechanicalstresses. Simultaneously, the amplifiers areburned in at elevated temperatures to eliminatepremature component failures. The electronicamplifier assembly and sensors are then

matched, assembled and welded together toform the complete transmitter. The completedunit is then performance tested in anenvironmental chamber at temperatures to

180F (82C) to verify characteristics within theoperating thermal band.

Measurement ReferenceThe PA/PG3000 Series transmitters feature asealed gage sensor with a fixed reference of14.7 psi. This sealed gage sensor allows thetransmitter to be electronically offset to simulate0 psia for vacuum applications. (For furtherdetails on measurement reference refer toSection IV, Calibration.)

Small Lightweight, Easily MountedThe hybrid DC electronics of the PA/PG3000Series is simple and reliable, requiring far lessspace than in competitive transmitters. The

small size electronics enclosure, made of CRES316 steel, provides a lighter and more ruggedunit, for easy and inexpensive mounting.

Output Damping/Response Time

The PA/PG3000 Series pressure transmittersare offered standard with a damped responsetime of 300 milliseconds for a 63% step to inputpressure change. An optional fast response ofless than 10 milliseconds is available (see Figure

1.3).

SECTION IIMECHANICAL INSTALLATION

GeneralMost problems associated with pressuretransmitters are generally the result of improperinstallation. The importance of following theinstructions and considering therecommendations provided in this section cannotbe overemphasized.

Unpacking

The shipping container should be examinedcarefully before unpacking. If there are visiblesigns of significant damage, do not open thecontainer, but notify the carrier and Gulton-Statham immediately. If no external damage isapparent, the container should be opened andthe contents compared with the packing list. Thecarrier and AMETEK Gulton-Statham should beimmediately notified if there is equipmentdamage or shortage. Please do not return

goods without contacting AMETEK Gulton-Statham in advance.

Testing

All PA/PG3000 Series transmitters are factorycalibrated and performance verified prior toshipment. Customer testing before installation isusually unnecessary and not recommended inmost circumstances.

Storage & Shipment

For extended storage or for shipment, thetransmitter should be kept in its shippingcontainer. Do not remove plugs or covers. If thetransmitter has been installed, be sure allprocess fluid is completely drained from the unit.Clean the transmitter thoroughly if it has beenexposed to corrosive conditions while in service.Always store the transmitter in a suitableenvironment (see Section V, Maintenance,Storage, Shelf Life & Spares).

Location Selection

Gulton-Statham PA/PG3000 series transmittershave been specifically designed and constructedto operate in nuclear environments. It is,however, important to recognize that these areprecision measuring instruments whoseaccuracy, reliability and stability may have agreat influence on process efficiency and quality.For best results, the location should be selectedwith care.

Vibration & Shock

The influences of shock and vibration shouldalways be minimized. Vibration often occurs inlocations at certain times and under certainprocess conditions, and not at other times.Evaluate the conditions with care. See thespecifications section for the likely errorsassociated with vibration on transmitterperformance. It may be possible to reduce anyharmful influences of vibration by correctselection of the type of mounting, as well as thelocation. The stiffness and flexibility of themounting will have an effect as will the location

of the bracket and support structure. Closeattachment to a heavier component may wellreduce the vibration effect. Remember thatvibration forces can be transmitted through theprocess piping and fluids in the system, as wellas through the structure itself.

Temperature

In order to achieve optimum performance, thetransmitter should not be exposed to the high orlow temperature extremes. It is good practice tominimize, or avoid, sudden or large thermalvariations, which can affect performance.Consider all possible sources of temperature.Heat or cold may come from processconnections, ambient air, or by radiationemanating from cold or hot objects in closeproximity to the transmitter mounting location.Extended lengths of piping will generally providemore surface area for cooling (or heating) of hotor cold lines connecting to the transmitter. Useshields to block radiant and convective heat

transfer between hot or cold objects in closeproximity to the transmitter.

Accessibility

Direct access for adjustment or recalibration,while in service, should be a consideration whenselecting a mounting location. The zero andspan magnets should always be accessible.Also, the transmitter should be removable in theevent shop servicing is required. Considerationof optional equipment should also be made. Forexample, if a meter/junction box is incorporated,it must be accessible for convenient viewing andwiring.

Note:

Optional equipment included on the unit maybe determined from the model number on thetransmitter ID plate.

Mounting Location

Proper location of the transmitter with respect to

the process measurement is critical for accuratepressure measurements. For non-condensinggases, the transmitter should be located abovethe process taps (see Figure 3-1). For liquid orcondensing gases, the transmitter should belocated below the process taps (see Figure 3-2).Other general mounting considerations shouldinclude:

Impulse tubing should be kept as short aspossible and of sufficient diameter to avoidfriction loss.

Slope impulse piping at least 1 (one) inch perfoot up toward the process connections fornon-condensing gas.

Slope impulse piping at least 1 (one) inch perfoot toward the process connections forliquid or steam.

Ambient temperature extremes orfluctuations should be avoided.

Sediment should be kept from depositing inthe impulse tubing.

The transmitter should be isolated from hotor corrosive process fluids.

In dry leg applications, possiblecondensation in the impulse piping should beavoided.

For steam service, impulse tubing should befilled with water to prevent contact of livesteam with the transmitter.

NON-CONDENSINGGAS INSTALLATION

Figure 2.1 Non-Condensing Gas Installation

1. Mount the transmitter such that the impulsepiping connection is made from below thetransmitter.

2. Ensure there are no low spots in the impulsepiping between the process taps andtransmitter connection.

3. Slope the impulse piping at least one (1) inchper foot upward toward the process taps.

4. Install valving between the process taps andtransmitter to permit static equalization (zeroadj.) and process shut off.

1. Mount the transmitter such that the impulsepiping connection is made from above thetransmitter.

2. Ensure there are no vapor traps in theimpulse piping between the process taps andtransmitter connection.

3. Slope the impulse piping at least one (1) inchper foot upward to the process taps.

4. Install valving between the process taps andtransmitter to permit static equalization (zeroadj.) and process shut off

Process Connections

Process tubing should be installed so it will notproduce added mechanical stresses on the

transmitter during seismic disturbances. This isoften accomplished with the use of stress-relief

loops in the process tubing or by separatelysupporting the process tubing close to the

transmitter.

The PA/PG3000 Series transmitters are suppliedwith -14 NPT process connections asstandard.

Mounting Bracket Installation

The optional Model EW3 pipe mounting bracketcan be installed to provide a rigid support for thePA/PG3000 Series transmitter. The assemblykit comes with the mounting bracket, two (2)mounting screws with lock washers and nuts andU-bolt assembly ready for mounting the

transmitter to a 2 inch vertical pipe. A diagramof installation arrangement is shown in figure2.3.

The PA/PG3000 bracket is designed to bemounted vertically on a vertical pipe.

Junction Box O-ring

Field Replacement Procedure

Scope: During periodic maintenance

procedures, it may be necessary to remove thecover from the factory-installed junction box, toaccess field-wiring terminations. When thecover has been removed, it is recommendedstandard practice to replace the o-ring seal toensure proper sealing during reinstallation.

Procedure

1. By hand, remove the junction box cover fromthe housing by rotating in the counterclockwise direction until the threads arecompletely disengaged.

2. Remove the o-ring seal from the base of thethreads on the junction box cover andproperly dispose of it to ensure it will not bereused.

3. Wipe existing anti-seize thread compoundand contaminants from the external threadsof the junction box cover and the internalthreads of the junction box housing.

4. Apply a thin uniform coating of siliconelubricant to the new o-ring surface.

Note:

Silicone lubricant is utilized to aid in sealing andprevention of damage to the o-ring uponreinstallation of the junction box cover onto thejunction box housing.

5. Reinstall new o-ring.

6. Apply a new coating of anti-seize threadcompound on the external threads of thejunction box cover.

Note:

Prior to applying compound, visually inspect

threads and sealing surfaces to ensure nocontaminants which may affect proper threadengagement or sealing are adhering to theseareas.

7. With zero thread engagement rotate thejunction box cover a minimum of 8revolutions in the clockwise direction. Thiswill properly secure the cover and ensuresealing of the o-ring.

Note:

While o-ring will properly seal after 8revolutions, exceeding this until metal to metalcontact between the cover and housing is madewill not degrade the seal. The method forinstallation requires hand tightening only!

No tooling to assist fo r addit ional mechanical

leverage shou ld be util ized.

Transient Protection

The Gulton-Statham Model TP131 (see figures3.4 and 3.5) and Model TP114 TransientSuppressors (see figure 3.8) are designed toisolate any PA/PG3000 Series two-wire pressuretransmitter against damaging electricaltransients such as lightning or lightning inducedinductive switching (EMI), and electrostaticdischarge (ESD). A gas filled surge protectorand ultra-fast clamping circuit to provide a lowclamping voltage, which automatically shunts

damaging electrical transients to ground,protects each lead wire. The circuitry isenvironmentally protected against man-made oratmospheric conditions to provide extendedreliability. These transient suppressors are ratedas follows:

SURGE CAPACITY 5000 ampsMAXIMUM VOLTAGE SURGE 700 VdcADDED LOOP RESISTANCE 44 ohms

Installation

The TP131 is designed to install directly beneaththe terminal block of the Gulton-Statham MA130series, NEMA rated electrical enclosure (seefigures 3.7, 3.8 and 3.9). Its unique packagingrequires only that the terminal block is removedfrom the junction box and the TP131 be inserted.Additional assembly screws are supplied withthe TP131. These screws must be installed inplace to maintain electrical continuity from theterminal block, through the TP131, and to thetransmitter.

Figure 3.6 TP131 Electrical Schematic

Figure 3.7 - TP131 Exploded View

Figure 3.8 Junction Box Wiring with TP131

The TP114 is designed to install into theelectrical conduit connection of any PA/PG3000Series transmitter, or compatible electricalenclosure (see fig. 310). Its electroniccomponents are identical to the TP131 inperformance characteristics, but are housed in astainless steel tube, internally threaded at eachend. This allows simple installation between theconduit connection of the transmitter or electricalenclosure, and the electrical conduit.

can be supplied with factory molded Neopreneor Hypalon cabling (see figure 3.11). Thecabling consists of three 16 AWG tin/copperconductors, compression molded to the electricalconnection of the transmitter electronicshousing. The protective, corrosion resistantcover provides a reliable moisture proof seal.These cables can typically be submerged todepths of up to 500 feet (1000 psi externalpressure) without degradation of the moldedseal.

Figure 3.10 Factory Molded Cable

C100/101 (Quick) Electrical Connector

For applications which may require a quickdisconnect for ease of removal of the transmitter,

or require flexible electrical terminations, thePA/PG3000 series can be factory fitted with aGulton-Statham C100/101 electrical connector(see Figure 3.12).

The C100/101 assembly consists of the C100adapter, which is fitted to the electricalconnection of the transmitter electronic housingat the factory, and the C101 electrical connectorwhich is fitted with the field terminations by theuser. The C100 is a four-pin adapter in whichonly three pins are utilized: for the ground(Green Pin B), the positive (Black, Pin A), andthe negative (White, Pin D) terminations to thetransmitter. (See figure 3.12) The C101 is afour-pin MS3106F14S-12S type quickdisconnect receptacle with cable clamp.

SECTION IVCALIBRATION

Definition of Gulton-Statham Terms (Based on SAMAStandard PMC20-20-1-1973 Process Measurement andControl Terminology.)

Accuracy- Conformity of an indicated value toan accepted standard value or true value.Reference accuracy is the limit that errors willnot exceed when the instrument is used underreference operating conditions.

Calibration Adjustment of the output of adevice to bring it to a desired value, within aspecified tolerance, for a particular value ofinput.

Linearity The maximum deviation of anactual characteristic (average of upscale anddownscale readings) from a straight linepositioned so as to minimize the maximumdeviation.

Span The algebraic difference between theupper and lower range values.

Range The region between the limits withinwhich a quantity is measured or transmitted.

Elevation & Suppression of ElectronicPressure Transmitters(Definitions extracted from ISA STANDARD ANDPRACTICES FOR INSTRUMENTATION, 9

th Edition,

Volume 2, 1998.)

Range, Suppressed ZeroA range in whichthe zero value of the measured variable is lessthan the lower range value.

Range, Elevated ZeroA range in which thezero value of the measured variable, measuredsignal, etc., is greater than the lower rangevalue.

Range Value, Lower - The lowest value ofthe measured variable that a device is adjustedto measure.

Range Value, Upper The highest value of ameasured variable that a device is adjusted to

measure.

Proper Range Selection

The PA/PG3000 series transmitters are factorycalibrated, either to the customer-specified rangeor to the maximum span of the transmitter.Since the unit is hermetically sealed, provisionhas been made for zero and span adjustmentsthrough external screwdriver adjustablemagnets. The external adjustment screws arecoupled to internal zero and span potentiometersby the use of permanent magnets which are

mounted back to back on the transmitterhousing. Zero and span adjustments are non-interacting.

For gage pressure applications, proper rangeselection is of the greatest importance inensuring compatibility of the transmitter to theactual application. In most applications, thetransmitter type selected is predetermined by theenvironmental and physical limitation.

Each transmitter manufacturer may specify a

unique elevation and suppression limit based onthe turndown ratio capability of the electronicamplifier. To determine if a transmitter iscapable of the intended application, the followingformula (where LCV = lower calibrated value)can be utilized.

%Elevation or suppression = LCV x 100SPAN

The following rules apply:1. The elevation of a transmitters output cannot

exceed the maximum span.

2. The suppression of a transmitters outputcannot be greater than the maximum spanminus the minimum span.

Example:100 psi unit with 5:1 turndown ... 100 = 20

5100 0 20 = 80 psi/Max Suppression = 80 psi

Zero Elevation Applications

Zero elevation occurs when the transmitter isinstalled above the process connection. Theactual amount of zero elevation is determined bymultiplying the vertical distance between thetransmitter body and the process connection,times the specific gravity of the process media orfilled capillary leg (see Figure 4.1).

Figure 4.1 Elevated Zero Application

Elevation is treated as a negative valuebecause the static head created by theprocess or fill fluid, acts as a negativepressure on the transmitter. The termsuppressed span is often used for elevatedzero applications; however; the termelevated zero range is preferred to avoidconfusion for the actual calibration required

(see Figure 4.2).

Figure 4.2 Elevated Zero Example

Zero Suppression ApplicationsZero suppression occurs when thetransmitter body is installed below theprocess connection. Suppression of zerooutput may be achieved for differentialpressure, gage pressure, and remote sealapplications. The actual amount of zerosuppression is determined by multiplying thevertical distance between the transmitterbody and process connection, times thespecific gravity of the process media or filled

capillary leg (see Figure 4.3 and 4.4).

Figure 4.3 Suppressed Zero Application

Figure 4.4 Suppressed Zero Example

Compound Calibrations

Calibrations which require a reference (4mA)setting below atmospheric pressure and a span(20mA) setting above atmospheric pressure aregenerally referred to as compound calibrations.These types of calibrations are common toapplications in which vacuum is involved (see

Figure 4.6).

Figure 4.5 Gage vs. Absolute Pressure

Figure 4.6 Compound Pressure Calibration

Calibration for Vacuum Service

The PA/PG3000 Series can be calibrated for use

in absolute (vacuum) pressure service. Thesensor is sealed and is not subject to barometricpressure influence. It, therefore, can beelectronically offset to simulate an absolutepressure (see Figure 4.5). With an elevationcapability to full vacuum (-14.7 psi) the zerooutput (4mA) can be adjusted to 0 psia (-14.7psi).

Field Transmitter Calibration

For Field or Shop calibration, a dummy loadresistor may be substituted for the receivinginstrument. The dummy load (generally250 ohms) is installed in series with the loop. Adigital multimeter or VOM is connected to readthe output across the dummy load. A pressuresource of known accuracy should be connectedto the process or pressure connection of thetransmitter.

1. Apply the desired zero reference pressure or

vacuum. Adjust zero to indicate 4.00 mA.To decrease the output, turn the ZEROSCREW CCW; increase output, turn thescrew CW. Adjustment of the zero outputwill have no interaction with the span output.

SECTION V

MAINTENANCE, STORAGE,SHELF LIFE & SPARES

Maintenance

Unlike most electronic pressure transmitters, thePA/PG3000 Series transmitters require very littlemaintenance. The hermetically sealed designprevents intrusion moisture into the electronicsassembly, thus eliminating frequent replacementof electronics assembly. The hermetic designalso eliminates the requirement for O-ring sealsin the electronics enclosure, which requireperiodic replacement due to environmentalaging. In addition, only periodic verification ofthe zero reference calibration may be required toconfirm that no process variables have changedor altered the initial reference calibration. It willalso ensure that the transmitter is maintainingperformance within its published specifications.

Storage, Shelf Life & Spare Parts

Recommendations

The PA/PG3000 Series feature anenvironmentally protected electronics amplifier.The active electronic components are sealed inan all-welded stainless steel enclosure. Thisenclosure is rated for 100% relative humidity,therefore, eliminating special storagerequirements and additional spare partsinventories.

Storage & Shelf Life: Five (5) years at amaximum temperature of 100F (38C) in a

warehouse type environment. It is notnecessary to make special precautions forstorage. It is, however, suggested that the unitbe stored at, or near, room temperature and outof contact with direct sunlight. The transmitter isunaffected by relative humidity.

Spares Recommendations: With the greatlyreduced probability of electronics failure due tomoisture and other contaminants, no spare partsare required. In the unlikely event of a failure, it

is recommended that a minimum of one or twotransmitters are maintained as spares.

Consideration should be given for spares foroptional equipment ordered with thePA/PG3000. These would include the meter,junction box and/or transient suppressor device.

NACE COMPLIANCE & APPROVALS

NACE MR-01-75 COMPLIANCE

The NACE Standard is not a code document andis not intended for certification of the materialsand procedures described. This Standard wasprepared as a material requirement for oil fieldequipment. The NACE Committee, in itsMarch 15, 1979 Atlanta meeting, recognized theinadequacy in its treatment of processinstruments. The NACE Standard can serve asa useful guideline in selecting materials forhydrogen sulfide applications.

I. NACE Standard MR-01-75 (1984Revision) per Paragraph 1.2 applies toparts and materials exposed to sour gasenvironments. As defined in Paragraph1.3, Fluids containing water as a liquidand hydrogen sulfide.(which).maycause sulfide stress cracking (SSC) of

susceptible materials. The parts of thePA/PG3000 series transmitters that arenormally exposed to the processenvironment are process flanges, flangeadapters, and isolation diaphragmassemblies.

II. Compliance of the exposed portions

(wetted parts) in relationship to theStandard are:

A. Process Flanges and Flange Adapters

1. Stainless steel flanges and adapters are acasting of 315 CRES and comply with theStandard per Paragraph 3.6 and Table 2.

2. Hastelloy C flanges and adapters complyper Paragraph 4.1.5.1 and Table 3,

B. Isolation Diaphragm Assembly1. Diaphragms of Hastelloy C comply per

Paragraph 4.1.5.1 and Table 3. Isolationdiaphragms of 316 SS comply perParagraph 3.6 and Table 2.


24/29

III. Compliance of Fabrication Procedures:

A. The Hastelloy C. diaphragms use electricresistance welds. The heat affected zoneis extremely small and metallurgicalchanges in the weld zone are minimal.The intent of the Standard is met.

B. All exposed threads are cut and complywith the Standard per Paragraph 5.5.1.1.

C. Bolting is non-exposed per Paragraph 1.3and 6.3.

IV. Paragraph 1.3.1.2 defines specific areasin which off-the-shelf equipment may be

considered outside the scope of theStandard when used on crude oil, or twoor three phase crude, water and gas.Gulton-Statham has had years ofsuccessful service in these areas.

V. Other parts of the pressure transmitter,such as sealed CRES 316 steel electronicshousing, circuit boards, bolts, nuts, modulehousing, etc., are not exposed componentsas defined in Paragraphs 1.3.1 and 1.2 andare outside the scope of the Standard.

VI. Transmitters used in a closed environment(per Paragraph 6.2.1.2) are required to useB7M bolts, which will meet NACEspecifications.

Transmitters for Hazardous Locations

Gulton-Statham transmitters have beenapproved for use in hazardous locations byFactory Mutual Research (FM) and CanadianStandards Association (CSA). Foreignapprovals for selected agencies are alsoavailable (see Section II). Hazardous locationsare classified according to the properties of theflammable vapors, gases, dust and fibers thatmay be present, and the likelihood that acombustible concentration is present.Hazardous locations have been divided intoclass, division and group as described below.

Class I, Division 1,

Groups A, B, C & D

Class I, Division 1, locations are those in whichignitable concentrations of flammable gases orvapors may exist under normal operatingconditions. Electrical equipment for this class ofservice may be explosion-proof, intrinsicallysafe, purged, or otherwise protected to meetthe intent of Article 500 and 501 of the NationalElectrical Code.

Explosion-proof refers to the ability of a device

to withstand an internal explosion of a specifiedgas or vapor and prevent the ignition of externalgages or vapors when sparking, flashing orexplosions occur within the enclosure. Inaddition, the external temperature of the devicewill not ignite the surrounding atmosphere.

Intrinsically safe equipment and wiring areincapable of releasing sufficient electrical orthermal energy to cause ignition of specifiedgases or vapors in their most ignitableconcentrations.

Purged systems are designed to provide acontinuous source of clean air or inert gas undera positive pressure with effective safeguardsagainst failure, thus providing a non-hazardousatmosphere.

Equipment suitable for Class I locations is notnecessarily suitable for Class II or III locationsunless specifically identified as such.

For protection against static electricity hazards,see Recommended Practice on Static Electricity,NFPA 77-1977 (ANSI).

Class I, Division 2,Groups A, B, C & D

Class I, Division 2, locations are those in whichignitable concentrations of flammable gases orvapors may exist only under abnormal operatingconditions, failure of ventilating equipment orareas adjacent to Class I, Division 1, locationswhere vapors might occasionally accumulate.Class I, Division 1, equipment may be used forthis service.

Class II, Division 1,Groups E, F & G

Class II, Division 1, locations are those areaswhere combustible dust is normally present inthe atmosphere in such quantities that wouldsupport ignition or explosion. Equipment listedas suitable for Class II locations is dust-ignitionproof or otherwise designed andinstalled to meet the intent of Article 500 through503 of the national Electrical Code (NEC).

Dust-ignitionproof as used in the preceding

paragraph means that the enclosure of thedevice will exclude ignitable quantities of thedust that may affect the performance or rating, orwhere installed per code, will not allow sparks,arcs or heat to ignite materials external to theenclosure.

Class II, Division 2,Groups E, F & G

Class II, Division 2, locations are areas in whichcombustible dust will not normally be present in

sufficient quantities to support combustion, orinfrequently present in combustible quantitiesonly by the failure of electrical equipment orapparatus. Class II, Division I, equipment maybe used for this service.

Class III, Divisions 1 & 2

Class III, Divisions I and II, locations arehazardous due to presence of combustible fibersor flyings which are not normally present in theatmosphere in quantities that would supportcombustion.

The preceding classification definitions have

been taken from the 1981 edition of the NationalElectrical Code (NEC). Please consult thisreference for complete information regarding theselection and installation of devices forhazardous location service.

It is the users responsibility to select equipmentsuitable for the hazardous (classified) locationand install such equipment in accordance withpublished standards and approved codes.

Various equipment approved for hazardous

(classified) locations may be combined in asystem and approved as a system by arrangingfor site inspection by the applicable agency.

In addition to meeting the requirements forhazardous (classified) locations as defined bythe National Electrical Code (NEC), thePA/PG3000 series transmitters meet therequirements of the National ElectricalManufacturers Association (NEMA) for Classes3, 4, 6, 7 & 9 as defined below:

NEMA 3NEMA 3 enclosures are dusttight, raintight andsleet (ice) resistant suitable for outdoor service.

NEMA 4NEMA 4 enclosures are watertight, dusttight anddesigned to prevent seepage from a directstream of water.
