General DescriptionThe digital temperature transmitter TR12 range is designed for universal industrial use.

Comprehensive configuration possibilities, for example, type of sensor, measuring range and error signalling, high accuracy, galvanic isolation and EMI protection characterize these transmitters. The compact head mounting case fits in almost any DIN connecting head.

During configuration any one of 17 input signals can be selected. Measured temperatures are from - 200 °C up to + 2300 °C.

The following sensors can be connected:

y RTDs per EN60751, JIS C 1606, DIN 43 760 in 2, 3 and 4 - lead

connection, the connection system used is configurable and ensures an optimal lead wire compensation

y Thermocouples per IEC 584 , DIN 43 710 and ASTM E988. Cold junction compensation (CJC) is built-in, the use of an external CJC is selectable via configuration.

y Resistance-sensors up to 5 k W in 2 - , 3 - and 4 - lead connection, configurable compensation of the connection cable

y mV-sensors up to 800 mV

Configuration is carried out by means of a standard DOS PC using the Configuration set. With the Configuration Software the required parameters are defined. Data to the TR12 is down-loaded using a Communication-Interface (Programming Unit). The bi-directional communication enables display of the measured values on the PC.

Configuration can be effected whilst the transmitter is mounted in the field. The Communication-Interface has an integral isolation barrier which allows configuration whilst the transmitter is within hazardous areas, and acts to protect the PC. Configuration sets are available as an optional extra.

The transmitters are delivered with any customized configuration within the given limits.

General Description

Temperature transmitter for Pt100 in 2 or 3 wire connection with 4...20mA analogue output (loop powered 2 wire technique)

The TR24 temperature transmitter combines the known quick response of an analogue transmitter with the flexibility of configuration by means of a Windows PC.

The quick stabilisation of the output current after excitation voltage has been applied enables the use of this transmitter in multiplex systems.

Setting of the measuring range, type of sensor and sensor burnout be-havior takes only a matter of seconds thanks to the easy to use Win-dows configuration software. Time consuming adjustments and sensor simulation are not required for this transmitter.

The TR24 can be remotely configured from the control room via the current loop. Possible measuring errors which might for example, result from poor thermometer position, can be compensated by means of the function ‘sensor correction’.

Write protection and an increased ambient temperatures range com-plete the spectrum of features offered by the temperature transmitter.

Due to its flexibility and reliability the TR24 temperature transmitter is suited for a wide range of applications in the machine industry and plant construction.

As a result of its extremely compact design this TR24 temperature transmitter can be fitted into any DIN connection head of form B.

The transmitters are delivered with a basic configuration. Alternatively, upon request, transmitters can be delivered with a customized configu-ration within the given limits.

General Description

The TR32.xS transmitters are designed for universal use in the process industry. They offer high accuracy, galvanic isolation and excellent EMI protection.

Via HART® protocol, the TR32.xS temperature transmitters are configu-rable with a variety of open configuration tools. In addition to the dif-ferent sensor types (e.g. sensors in accordance with DIN EN 60751, JIS C1606, DIN 43760, IEC 60584 or DIN 43710), customer specific sensor-curves can also be defined, through the input of value pairs (user de-fined linearisation).

When configured for a sensor with redundancy (Dual sensor), on a sen-sor failure it will automatically change over to the working sensor.

Furthermore there is the possibility to activate Sensor Drift Detection. With this, an error signal occurs when the magnitude of the tempera-ture difference between Sensor 1 and Sensor 2 exceeds a user-select-able value.

The TR32 transmitter also has additional sophisticated supervisory func-tionality such as monitoring of the sensor wire resistance and sensor-break detection in accordance with NAMUR NE89 as well as monitoring of the measuring range. Moreover, this transmitter has comprehensive cyclic self monitoring functionality.

The dimensions of the head-mounted transmitter match the Form-B DIN connecting heads with extended mounting space, e.g. Rototherm’s H70.

The rail-mounted transmitters can be used for all standard rack systems in accordance with IEC 60715.

The transmitters are delivered with either a basic configuration or con-figured according to customer specifications.

Monitoring functionality with 2 sensors connected (dual sensors).

RedundancyDuring a sensor failure (sensor break, wire resistance too high or below the sensor measuring range) of one of the two sensors, the process value is based only on the error free sensor. Once the error is resolved, the process value (output) is once again based on both sen-sors, or on Sensor 1.

Ageing-control (sensor-drift-monitoring)An error signal is activated if the magnitude of the temperature differ-ence between Sensor 1 and Sensor 2 exceeds a user selected value. This monitoring function only signals a failure when two valid sensor values are measured and the temperature difference exceeds the selected limit value. (Not available for the sensor functionality “differ-ence”, since the output signal is already defined by this value).

Sensor functionality with 2 sensors connected (dual sensor)

Sensor 1, Sensor 2 redundantThe 4 ... 20 mA output signal delivers the process value from Sensor 1. If Sensor 1 fails, the process value is taken from Sensor 2 (Sensor 2 is redundant).

AverageThe 4 ... 20 mA output signal delivers the average value from Sensor 1 and Sensor 2. If one sensor fails, the process value is taken from the error-free sensor.

MinimumThe 4 ... 20 mA output signal delivers the minimum value with respect to Sensor 1 and Sensor 2. If one sensor fails, the process value is taken from the error-free sensor.

MaximumThe 4 ... 20 mA output signal delivers the maximum valuewith respect to Sensor 1 and Sensor 2. If one sensor fails, the process value is taken from the error-free sensor.

Difference *)The 4 ... 20 mA output signal delivers the difference between Sensor 1 and Sensor 2. If one sensor fails, an error signal will be activated.

*) This operating mode is not allowed at option SIL (TR32.xS.xx-S).

Note: The transmitter can be configured below these limits but is not recommended due to loss of accuracy.

Wiring Details

The slidewire input version of the TR48 produces a linear output proportional to the position of the wiper of a slidewire or poten-tiometer. This provides a convenient way of remotely indicating or controlling the position of any motorised actuator fitted with a re-transmission potentiometer.

Differential transmitters produce an output proportional to the difference between two precision Platinum Resistance Thermometers.

A typical application might be to monitor the efficiency of a piece of plant by detecting the heat loss or gain between input and output. In such applications it is often necessary to measure very small differences. Using a differential transmitter with a span of 20ºC, a resolution of 0.01ºC can easily be achieved using only a low cost digital panel meter.
