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...20 mA current signal.

Technical characteristics

  • Within a few seconds the user can program PR6331B 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 limit can be programmed on the output signal.
  • Continuous check of vital stored data for safety reasons.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. Using the 2-channel version, up to 84 channels can be mounted per meter.
  • The 6331B can be mounted in zone 0, 1, 2 and zone 21, 22 including M1 / Class I, Division 1, Groups A, B, C, D.
