SITRANS TH320/420 is designed to support all common resistance thermometers and thermocouples. It also evaluates resistance and millivolt signals. Setup is quick and easy with the SIMATIC PDM or the Handheld Communicator. Both temperature transmitters SITRANS TH320 and TH420 combine perfect measurement and intelligence for every temperature and condition. The true reliability of the SITRANS TH420 is exemplified by the dual sensor input with 4-wire sensor connection and hot backup function. In case of a sensor failure, the transmitter seamlessly switches to the second sensor, so that the data is recorded continuously and without any loss.
High availability during measurement by hot backup function (SITRANS TH420)
High reliability and long-term stability – sensor trim (Callendar-van-Dusen) and sensor drift detection (SITRANS TH420 only) for high accuracy and accelerated calibration time
Avoidance of production stop because of measurement failures
Best cost-benefit ratio for facility management
Cost reduction through anticipatory maintenance
Withstanding safety-critical environments - Extended temperature range up to -50°C and SIL2/3 approvals
Controlling your process every step of the way with SITRANS T
The most widely used measurement in many diverse industries, accurate and reliable temperature monitoring is critical to your processes. Take advantage of Siemens wide range of devices for temperature measurement and you will find both significant savings and improvements to your operations.
