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 PR6335A 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 6335A provides the required failure data (SFF and PFDAVG) for SIL applications as per IEC 61508 / IEC 61511.
  • A limit can be programmed on the output signal.
  • 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. Using the 2-channel version up to 84 channels per metre can be mounted.
  • Configuration via standard HART communication interfaces or by PR 5909 Loop Link.
  • The 6335A can be mounted in zone 2, 22 / Class I, Division 2, Groups A, B, C, D.
