SMART TEMPERATURE SENSORS Turck TS400 and TS500 temperature sensors are platinum resistance temperature detectors (RTDs). The sensors may be mounted directly or remotely, and sense a temperature range of -50º C to 500 ºC (-50 ºF to 932 ºF). Available process connections include compression fittings, thermowells and tri-clamp fittings. TS400 and TS500 sensors are available with two switch points, an analog current output with one switch point, and an analog voltage output with one switch point. Multiple outputs are programmed via pushbuttons, and do not require regular maintenance calibration. A recessed “enter” key helps prevent unintentionally altering stored values.
