Siemens introduces new temperature transmitters
15 May 2018
With Sitrans TH320/420 and TR320/420, Siemens has introduced a new generation of reliable WirelessHART 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 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. Electronic device descriptions 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.
