Series 8431 - Resistance Thermometer with Transmitter
Compact design
 
 
Description
Series 8431 integrated temperature transmitter is used to measure gas and liquid media.

This series of resistance thermometers are equipped with integrally welded thermowell and threaded process connection that can be directly installed. The form without process connection can also be realized. Standard DIN L-plug, M12×1 or cable outlet can be used for electrical connection.

The integrated temperature transmitter integrates an output signal 4 20 mA transmitter. It ensures the simple and reliable transmission of the measured temperature signal value.
