PR 5437 2-Wire HART 7 Temperature Transmitter

PR 5437 2-Wire HART 7 Temperature Transmitter

The PR 5437 is a high-end, 2-wire universal HART temperature transmitter designed for the most critical and demanding applications. It sets itself apart with a “true dual input” design, featuring a high-density 7-terminal configuration that allows it to accept a wide variety of sensor combinations, including two 4-wire RTDs. This enables advanced features like sensor redundancy, which provides an automatic backup in case of primary sensor failure, and sensor drift detection. The unit boasts exceptional accuracy (0.014%), a very wide ambient operating temperature range of -50°C to +85°C, and a full functional safety assessment up to SIL 3, making it a robust and reliable choice for safety-critical systems

Description

Applications

  • Linearised temperature measurement with PT100/1000, Ni100/1000, or Thermocouple sensor.
  • HART communications and 4-20mA analouge PV output.
  • Difference or average temperature measurement of 2 resistance or TC sensors.
  • Conversion of linear resistance variation to a standard analogue 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 63 transmitters can be connected in a multidrop cummincation setup (HART 7)

Features

  • RTD, Thermocouple, Ohm, or bipolar mV input
  • Galvanic isolation
  • For DIN form B sensor head mounting
  • Extremely high measurement accuracy
  • HART® communication

HART Protocol

The HART protocol provides a uniquely backward compatible solution for instrument communication as both 4-20 mA analog and digital communication signals are transmitted simultaneously on the same wiring. The Loop Link Programming Kit can configure the individual transmitters for multidrop mode and provide it with a unique polling address. The HART protocol revisions can be changed by user configuration to either the HART 5 or HART 7 protocl. HART provides many benefits promised by fieldbus, while retaining the compatibility and familiarity of existing 4-20mA systems.

HART® 7 protocol offers:

  • Long tag supported (up to 32 characters).
  • Enhanced Burst Mode and Event Notification with time stamping possibillity.
  • Device variables with status, can be mapped individually to any dynamic variable PV, SV, TV or QV.
  • Measuring of trending in the process signal.
  • Automatic event notification with time stamps.
  • Command aggregation for higher communication efficiency.
