SITRANS TR320/420_Rail-Mounted Temperature Transmitter

The SITRANS TR320/420 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 interface. Both the SITRANS TR320 and TR420 temperature transmitters combine ideal measurement performance tailored to each specific temperature and condition with intelligent transmitter technology. The SITRANS TR420 ensures true measurement reliability through its dual 4-wire sensor connection and robust hot-backup functionality. If one sensor fails, the transmitter seamlessly switches to the backup sensor, enabling 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 TR420) ensure high accuracy and accelerate 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.
