HART®, FOUNDATION Fieldbus™ or PROFIBUS® temperature field transmitter with two universal sensor inputs suitable for use in hazardous areas and SIL 2. Universal input usable for resistance thermometer (RTD), thermocouple (TC), resistance thermometer (Ω), voltage transmitters (mV). HART® protocol for converting various input signals to a scalable 4 to 20 mA analog output signal. Operating the transmitter using handheld terminals Field Xpert SFX350/370, field communicator 475 or remotely via PC. FOUNDATION Fieldbus™ ITK 6.1.2. PROFIBUS® PA Profile 3.02. Optional: stainless steel housing for hygienic or Ex d application
