Model TT212 Thermocouple Temperature Transmitter
Brand: Tel-Tru Manufacturing Co.The TT212 loop-powered transmitter recieves and measures signals from thermocouples and sends an output current of 4-20 mA which is directly proportional to the thermocouple millivolt input.
A TT212 transmitter is available for thermocouple sensor types J, K, T, or E. The wide temperature range make the TT212 an excellent choice for temperature signal transmission.
It is factory calibrated for fixed range and designed for highest performance and lowest cost.
Precision 20-turn potentiometers allow fine adjustment of ZERO and SPAN. TT212 is DIN rail-mounted conforming to DIN standard 46277 package which is very compact.
