TST series temperature transmitter is the high performance temperature transmitter that accepts RTD (Pt100, Pt1000), inputs and converts it to a 4 to 20 mA DC or 0 to 5 V DC or 0 to 10Vdc signal for transmission.
The transmitter features three-wire current output, voltage output, or low or high temperature alarm option, and can be fitted externally 1/2" NPT connection or an flange. The operating temperature range is from -70ºC to 750ºC. The working pressure is from 2.5 to 5.0 Mpa. The LCD display can be selected.
