PR electronics 7501A Field mounted HART temperature transmitter. Low copper aluminum material. Linearized temperature measurement with TC and RTD sensors e.g. Pt100 and Ni100. HART communication and 4...20 mA analog PV output for individual, difference or the average temperature measurement of up to two RTD or TC input sensors. Conversion of linear resistance to a standard analog current signal, e.g from valves or Ohmic level sensors. Amplification of bipolar mV signals to standard 4...20 mA current signals. Up to 63 transmitters (HART 7) can be connected in a multidrop communication setup.
