TST 181
temperature transmitter
Input: 2 or 3 wires PT100, thermocouples
output: analogue 4-20mA

TST181 is a 2 wire temperature transmitter, used with RTD and thermocouple, mounted in the connection head. The input signals could be 2 or 3 wires PT100 and all kinds of thermocouples, doing the linearization of the input signals, and output 4-20mA standard signal. The user could program it with handhold instrument MD-I.
