Head Mount Temperature Transmitter — TTH Series

TTH Series

The head mount temperature transmitter fits inside a DIN Form B sensor head. It converts RTD, thermocouple, mV, resistance or potentiometer input into a stable 4-20mA output. Also, it supports USB or optional HART communication as per configuration. Therefore, it helps reduce signal interference by converting the signal close to the measuring point.
