General Description
The 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:

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