PR 5331 2-Wire Programmable Transmitter

The PR 5331 offers the most flexibility in the PR range of head-mounted transmitters. The PR 5331 is a universal input device, accepting RTD, Thermocouples, Linear Resistance and Bi-Polar mV signals. This broad capability offers significant advantages, allowing for a single transmitter type to be stocked for multiple applications, thereby drastically simplifying inventory management and reducing maintenance overhead. Beyond its versatility, the PR 5331 is engineered for superior performance, featuring an impressive measurement accuracy of better than 0.05% of span. It also incorporates robust 1.5 kVAC galvanic isolation, which provides essential protection against electrical noise and ground loops, ensuring signal integrity and system reliability in harsh industrial or ATEX environments.

PR5331A 2-Wire Programmable Transmitter

PR5331D 2-Wire ATEX Programmable Transmitter

Description

The PR 5331 series is a highly versatile programmable transmitter, designed to handle a wide range of measurement tasks. Its universal input capability makes it the ideal ‘go-to’ device for new installations and a crucial component for simplifying your maintenance and spare parts management.

Versatile Input Capability

  • Linearised RTD Measurement: Convert signals from virtually any PT100, PT1000, Ni100, Ni1000 to a standard 4-20mA output.
  • Linearised Thermocouple Measurement: Types B, E, J, K, L, N, R, S, T, U, W3, W5 or LR Thermocouples to a standard 4-20mA output.
  • Resistance Conversion: Convert linear resistance changes (e.g., from potentiometers, valves, or Ohmic level sensors) to a standard 4-20mA signal.
  • mV Signal Amplification: Amplify low-level bipolar mV signals to the standard 4-20 mA output, perfect for pyranometers, pressure transducers, LVDT’s, etc.

Features

  • Universal Input (RTD, TC, Ohm, mV): The single most valuable feature for stock control. A single PR 5331 unit can replace multiple specific-input transmitters, drastically reducing your spare parts inventory and simplifying procurement.
  • High Measurement Accuracy: With an accuracy of better than 0.05% of the selected range, you can trust your readings for critical process control, regardless of the input type.
  • Galvanic Isolation (1.5 kVAC): Protects both the transmitter and your control system from ground loops and electrical noise, ensuring a clean and reliable signal in electrically harsh environments.
  • PC-Programmable: Simple and intuitive configuration via the PR 5909 Loop Link communications interface. Set up the unit in minutes, not hours, for any application.
  • Sensor Error Detection (NAMUR NE43): Continuously monitors for sensor failures (e.g., short or open circuits). You can program the output to a specific fail-safe value (e.g., 3.5mA or 23mA) to immediately alert operators and prevent process errors.
  • Durable & Compact Design: Designed for DIN form B sensor head mounting, its compact size fits easily into standard enclosures, while its robust construction ensures long-term reliability.
  • 5 Year Warranty: 5 Year Warranty on all Omni Instruments Supplied PR 5331 Transmitters. Warranty covers defects in construction, material, or production.
