Application

  • Linearized temperature measurement with TC and RTD sensors e.g. Pt100 and Ni100.
  • HART communication and 4…20 mA analog PV output for individual, difference or average temperature measurement of up to two RTD or TC input sensors.
  • Conversion of linear resistance to a standard analog current signal, e.g from valves or Ohmic level sensors.
  • Amplification of bipolar mV signals to standard 4…20 mA current signals.
  • Up to 63 transmitters (HART 7) can be connected in a multidrop communication setup.

Technical characteristics

  • HART protocol revision can be changed by user configuration to either HART 5 or HART 7 protocol.
  • The HART 7 protocol offers:
    • Long Tag numbers of up to 32 characters.
    • Enhanced Burst Mode and Event notification with time stamping.
    • Device variable and status mapping to any dynamic variable PV, SV, TV or QV.
    • Process signal trend measurement with logs and summary data.
    • Automatic event notification with time stamps.
    • Command aggregation for higher communication efficiency.
  • 5337A is designed according to strict safety requirements and is therefore suitable for applications in SIL installations.
  • Continuous check of vital stored data.
  • Meeting the NAMUR NE21 recommendations, the 5337 HART transmitter ensures top measurement performance in harsh EMC environments. Additionally, the 5337 meets NAMUR NE43 and NE89 recommendations.

Mounting / installation

  • For DIN form B sensor head or DIN rail mounting via the PR fitting type 8421.
  • Configuration via standard HART communication interfaces or by PR 5909 Loop Link.
