The Sitrans TH320/420 and TR320/420 HART temperature transmitters (photo) cover 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, these 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 down to –50°C. Main application areas include industries such as chemical, oil and gas, marine and power generation. — Siemens AG, Nuremberg, Germany
