Application

  • Linearized temperature measurement with Pt100...Pt1000, Ni100...Ni1000, or TC sensor.
  • Difference or average temperature measurement of 2 resistance or TC sensors.
  • 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.
  • Connection of up to 15 channels to a digital 2-wire signal with HART communication.

Technical characteristics

  • Within a few seconds the user can program PR6335D 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.
  • The 6335D has been designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.
  • Continuous check of vital stored data for safety reasons.
  • Sensor error detection according to the guidelines in NAMUR NE89.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without any distance between neighboring units, up to 84 channels can be mounted per meter.
