Accuracy
(Pt100, -50...200 °C) <= 0,2 K
(Pt100, -58...392 °F) <= 0,4 °F
Field of application
Unsurpassed reliability, accuracy and long-term stability in critical processes over all industries. The configurable transmitter not only transfers converted signals from resistance thermometers (RTD) and thermocouples (TC), it also transfers resistance and voltage signals using HART® communication. It can be installed as an intrinsically safe apparatus in Zone 1 hazardous areas. Swift and easy operation, visualization and maintenance by PC using operating software.
Temperature head transmitter with HART® -protocol for converting various input signals into an scalable 4 to 20 mA analog output signal
Input: Resistance thermometer (RTD), thermocouple (TC), Resistance transmitter (Ω), voltage transmitter (mV)
HART® -protocol for front end unit or panel unit operation using the hand operating module (DXR275, DXR375) or PC (e. g. ReadWin 2000 or FieldCare)
Benefits
Front end unit or panel unit operation using the hand operating module or PC
