PR Electronics 4500 Temperature Transmitter 300V dc, -40°C to 80°C 5437D1S

PR Electronics 5437D1S 4500 Series Temperature Transmitter is engineered for demanding process control applications requiring precise temperature measurement and signal transmission. With an operating voltage capacity of 300V dc and an input temperature range from -200°C to 850°C, it offers exceptional versatility and reliability in both standard and hazardous industrial environments.

This transmitter supports multiple sensor types including two, three, or four-wire RTDs, thermocouples, potentiometers, and bipolar mV signals, with sensor redundancy features to ensure continuous operation even if a primary sensor fails. The device outputs a stable 4 - 20 mA signal and supports modern HART communication protocols (HART 5 & HART 7), offering flexible integration and future-proof communication options.

Designed with a compact form factor - 44 mm diameter and 20.2 mm depth - the 5437D1S facilitates seamless installation using a 1/4 inch centre hole adaptable to various probe mounting diameters. Wiring access can be made from inside or outside terminals, and on-board LEDs provide fault and loop status feedback compliant with NAMUR NE44 and NE107.

Certified for hazardous areas with approvals including ATEX, IECEX, FM, and SIL 2 functional safety, this temperature transmitter meets strict industrial safety and quality standards. Its high galvanic isolation (2.5 kVAC / 55 VAC) protects against ground loops and electrical interference, ensuring accurate and stable measurements in challenging environments.
