General Description
The TR32 digital temperature transmitter is designed for universal use in the process industry.

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

During configuration, by means of a HART communicator model 275 or an FSK modem (eg VIATOR) via the RS 232-C on a standard DOS PC, any one of 15 types of sensor can be selected. Measured temperatures are from -270ºC up to 1820ºC.

The following sensors can be connected:

• RTDs per EN 60 751 resp. 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 1200 mV

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