Application

  • Linearized temperature measurement with Pt100…Pt1000, or Ni100…Ni1000 sensor.
  • Conversion of linear resistance variation to a standard analog current signal.

Technical characteristics

  • Within a few seconds the user can program PR5802 to measure temperatures within all RTD ranges defined by the norms.
  • The RTD and resistance inputs have cable compensation for 3-wire connection.

Mounting / installation

  • For tube mounting, e.g. M18 barrel housing or customer specific housing.
  • The unit is tested with an M12 connector, mounted in a steel housing and molded with Silgel 612 silicone molding compound. This is PR electronics’ recommended method to comply with specifications and EMC data.
