Application • Linearized temperature measurement with Pt100...Pt1000, Ni100...Ni1000, or TC sensor. • Conversion of linear resistance variation to a standard analog current signal, for instance from valves or Ohmic level sensors. • Amplification of a bipolar mV signal to a standard 4 to 20 mA current signal. Technical Characteristics • Within a few seconds the user can program PR5331A to measure temperatures within all ranges defined by the norms. • The RTD and resistance inputs have cable compensation for 2/3 and 4-wire connection. • A continuous check of vital stored data for safety reasons.
