Field of application
iTHERM CompactLine TM311 sanitary thermometer provides accurate and fast process temperature measurements in hygienic and aseptic applications. Its temperature sensor offers a 4-wire connection or feeds into a smart temperature transmitter with 4 to 20 mA, IO-Link (auto-detect) or switch output. Featuring TipSens technology, the RTD (Pt100; Class A) delivers response times as low as 1.5 s (t90) for optimum process control. This versatile device is a great choice to drive plant standardization.
