PR 5335D 2-wire transmitter with HART protocol

PR 5335D
  • PR 5335D 2-wire transmitter with HART protocol
Features
  • RTD, TC, Ohm, or mV input
  • Extremely high measurement accuracy
  • HART 5 protocol
  • Galvanic isolation
  • For DIN form B sensor head mounting

    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 transmitters to a digital 2-wire signal with HART communication.

    Technical characteristics

  • Within a few seconds the user can program PR5335D 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 5335D has been designed according to strict safety requirements and is therefore suitable for application in SIL installations.
  • Continuous check of vital stored data for safety reasons.
  • Sensor error detection according to the guidelines in NAMUR NE89.
