Head Mount Temperature Transmitter

TTH Series

The TTH Series Head Mount Temperature Transmitter is a compact, microprocessor-based device designed to be installed directly inside the sensor head (DIN Form B). It converts temperature signals from RTDs, thermocouples, mV, resistance, and potentiometer inputs into a stable 4–20 mA output with optional HART communication. By conditioning the signal at the source, it minimizes interference, improves accuracy, and ensures reliable measurement in harsh industrial environments.

Accurate measurement directly at sensing point
Minimizes signal noise and transmission losses
Reduces wiring cost and installation complexity
Improves reliability in harsh environments
Universal input reduces spare inventory
