PR 6337A 2-wire HART Temperature Transmitter

Description

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.
• 6337A 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 6337A HART transmitter ensures top measurement performance in harsh EMC environments. Additionally, the 6337A meets NAMUR NE43 and NE89 recommendations.

Mounting / installation

• DIN rail mounting with up to 84 channels per meter.
• Configuration via standard HART communication interfaces or by PR 5909 Loop Link.
• The 6337A can be mounted in zone 2, 22 / Class I, Division 2, Groups A, B, C, D.
