2-Wire Programmable Transmitter With Universal Input

Description

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.
