Model TT112 Thermocouple Temperature Transmitter
Brand: Tel-Tru Manufacturing Co.The TT112 loop-powered transmitter receives and measures signals from thermocouples and sends an output current of 4-20 mA which is directly proportional to the thermocouple millivolt input.
A TT112 transmitter is available for thermocouple sensor types J, K, T, or E.
The wide temperature range makes the TT112 an excellent choice for temperature signal transmission. It is factory calibrated and designed for highest performance and lowest cost.
Precision 20-turn potentiometers allow fine adjustment of ZERO and SPAN. TT112 units fit into industry standard connection heads.
Features- 2-wire loop-powered 4-20 mA output
- Linearized output to voltage
- Input T/C with cold junction compensation
- Analog design, potentiometer adjustable
- Factory calibrated fixed ranges
