SITRANS TH320/420_Temperature Transmitter Module

The SITRANS TH320/420 supports all common resistance thermometers and thermocouple inputs, and it can also measure signals from resistance and millivolt sensors. Setup is quick and convenient, thanks to SIMATIC PDM or a handheld operator device. The SITRANS TH320 and TH420 combine ideal measurement performance with intelligent transmitter capabilities tailored for every temperature range and operating condition. The SITRANS TH420 ensures true measurement reliability through its dual 4-wire sensor connection and robust hot backup feature. If one sensor fails, the transmitter seamlessly switches to the backup sensor, allowing continuous data recording without any interruption or loss.

Advantages
- High availability during measurement
- High reliability and long-term stability – Sensor transmitter matching (Callendar-van-Dusen) and sensor drift detection (available only on SITRANS TH420) ensure high accuracy and speed up calibration.
- Prevent production stoppages caused by sensor failures
- Excellent cost-effectiveness for facility management
- Reduce costs through predictive maintenance
- Suitable for use in environments with extremely high safety requirements—operating temperature range extends down to -50°C and is SIL2/3 certified.
