EMAT TransducerAn EMAT (Electro Magnetic Acoustic Transducer)

uses the Magnetostrictive principle to generateshear wave sound energy in ferrous metals that

are externally coated with high temperature oxide

scale.

The EMAT transducer does not require the use of

ultrasonic couplant. If the scale is not fully bondedto the surface of the steel, the shear wave sound

energy will not be transmitted into the metal.

E110-SB

25/192

EMAT Transducer

EMAT transducers are designed to be a quick way of

determining the approximate wall thickness without

removing the external oxide scale.

The E110-SB EMAT transducers generate shear sound

waves in the steel material.

The EMAT transducers create a non-focused signal and

is designed to give a good estimate of the remaining wall

thickness (+/-0.010 in or +/-0.25 mm)

EMAT transducers are relatively insensitive to smallinternal pits.

The minimum capability is approximately 0.080 in.

LCB-74-4

37DL PLUS

The 1/2XA/E110 filter adapter must be

plugged in to the transducer connectors

located at the top of the 37DL PLUS. The

E110-SB can then be connected to the

1/2XA/E110 adapter box using a standard

Lemo to BNC cable part number LCB-74-4.

The 37DL PLUS will automatically recall

the default setup for the E110-SB EMAT

transducer when the Adapter and E110-SBtransducer is plugged in. The gage is now

ready to take thickness measurements of

steel that is coated with external scale

using the default setup.

Using Gain with the EMAT TransducerWhen using the E110-SB EMAT transducer it will often be necessary to adjust thegain level in order to make proper echo detection. This is due to the variation insignal amplitude caused by changes in the external oxide thickness and surfaceconditions.

Temperature Compensation FeatureThe sound velocity in Steel changes approximately 1% per 1000F (550C) change in

temperature as recommended by ASME Standard E 797-95.

Compensated Thickness = Time of Flight *V0(1+k(T1-T0))

k is typically -0.0001 for (0F) and -0.00018 for(0C)

A blank zone that protects the receiver from false readings generatedby the Main Bang

Indicates the point in time where the gage begins to search for echoes

Adjustment directly affects the minimum thickness the gage can

measure in Mode 1

Set just past the Initial Pulse in Mode 1

Set just before the Interface Echo in Modes 2 and 3

Make sure that the Main Bang Blank is always set before the Interface

Echo from the shortest water path when using immersion transducers

This indicates the detection polarity of the "first detected back wall

signal" in the Echo Window in Mode 1

In Modes 2 and 3 it refers to detection polarity of Interface (or delay

line) Echo

Always choose the detection polarity on the singular lobe of the echo

Echo polarity is affected by:

Acoustic impedance

Echo distortion from grain structure, internal fibers, and surface

conditions

Oxide/Scale can build up on the inside of boiler tubes The oxide that builds up acts as an insulator.

This effects the heat transfer from outside the tube to the water inside the

tube

The tubes runs at a higher temperature then they were designed for and they

start to thin faster. Knowing both the thickness of the steel and internal Oxide the remaining

tube life can be more accurately predicted

Activating Oxide Software


181/192

181

The oxide software is a paid option for the 37DL PLUS. It can be

purchased at the time the units is purchased or the 37DL PLUS can be

upgraded to this feature in the field. If the unit was purchased along

with the oxide software it will be installed and activated when you

receive it.

If it is upgraded after the unit was purchased then it will have to beinstalled and then activated using a unique License Code.

Gages loaded with Software version 1.XX do not have the internal

oxide software installed.

Gages loaded with Software version 2.XX do have the software loaded

but you will need to purchase a unique License Code to active it.

Please contact your Panametrics representative for information

concerning upgrading or activating oxide software for your 37DL PLUS
