PR 5331 2-wire Temperature Transmitter

The PR 5331 2-Wire Temperature Transmitter is a precision industrial signal transmitter for accurate temperature measurement and seamless integration into process control systems. The 5331 Series, from PR electronics, is capable of accepting a wide range of sensor inputs, including RTDs (Pt100-Pt1000, Ni100-Ni1000), thermocouples (types B, E, J, K, L, N, R, S, T, U, W3, W5, LR), linear resistance, as well as millivolt signals. This versatile, programmable, head-mounted temperature transmitter converts real-world temperature readings into a standard 4-20 mA analog output for reliable loop-power operation.

• Linearized temperature measurement with Pt100-Pt1000, Ni100-Ni1000, or thermocouple (TC) sensors. 
• Conversion of linear resistance variation to a standard analog current signal, for example, from valves or Ohmic level sensors.
• Amplification of a bipolar mV signal to a standard 4-20 mA current signal.
• Models in the 5331 Series are intrinsically safe and feature multiple, different certifications for use in hazardous areas, including, ATEX, CSA, and IECEx, and is also suitable for use in marine applications.
• Model PR 5331A is certified for hazardous areas Zone 2 / Div. 2.
• Model PR 5331D also includes FM certification and is suitable for Zone 0, 1, 2, 21, 22, M1 / Div 1, Div 2.

PR 5331 2-wire Temperature Transmitter from PR electronics

The PR 5331 2-wire Temperature Transmitters features measurement accuracy better than ±0.05 % of the selected range as well as a fast programmable response time of 1–60 s. As a result, the 5331 Series ensures precise and stable temperature readings even in demanding industrial environments. Its 1.5 kVAC galvanic isolation enhances signal integrity by minimizing electrical noise and interference, thus the PR 5331 Series is ideal for use in process automation, manufacturing, and energy monitoring applications.

• Within a few seconds, users can program the PR 5331 Series to measure temperatures within all ranges defined by the norms.
• RTD and resistance inputs have cable compensation for 2-, 3-, and 4-wire connection.
• Continuous check of vital storage data for safety reasons.

Easy Mounting, Installation, and Programming

The PR 5331 2-wire Temperature Transmitter supports programmable sensor error detection and NAMUR NE43 upset/downscale signaling. Thus, the 5331 enables proactive diagnostics and enhances safety in control loops. Compact and flexible, the PR 5331 Series can mount in a DIN form B sensor head or on a DIN rail with optional fittings, simplifying installation across diverse industrial settings.

• Perfect for DIN form B sensor head mounting.
• Model PR 5331A can also mount on a DIN rail with the fitting type PR 8421.
