Transmitter offers high reliability in temperature measurement

With Sitrans TH320/420 and TR320/420, Siemens introduces a new generation of reliable HART (Highway Addressable Remote Transducer Protocol) temperature transmitters for a wide range of sensor types suitable for mounting in sensor head and rail mounting. They feature high availability of the measurement signal and ease of use. Due to the safety integrity level (SIL) 2/3 certification according to IEC 61508 the temperature transmitters are particularly suited for safety-critical applications. The devices also have a large number of country specific explosion protection certificates for all zones. They provide reliable results even under extreme conditions up to -50°C. Main application areas include industries such as chemical, oil and gas, marine and power generation.

With fast and accurate sensor and transmitter tuning, the use of the Callendar-van Dusen method or 60-point-curve ensures highest measuring accuracy. Deviations can be detected and monitored through the drift detection with dual-channel transmitters, e. g. for preventive maintenance. Electronic device descriptions (EDD, DTM and FDI) allow the new transmitters to be used in all current distributed control systems. A quick start wizard is just one example of their user-friendly features.

Measurement values, device functions and visual alarm signals can be displayed and operation planning and implementation is very convenient using special visualization components for Simatic PCS 7 (Sitrans Library).
