PR Electronics 4500 Temperature Transmitter 300V dc, Operating Range -50°C to 85°C 5437D1

PR Electronics 5437D1 Temperature Transmitter is designed for industrial and process control applications requiring accurate temperature measurement with output conversion to a 4 - 20 mA signal. The transmitter supports a broad range of sensor inputs including thermocouples, RTDs, potentiometers, and bipolar millivolt signals up to 100 kΩ linear resistance. It can wire measurements using two, three, or four-wire RTDs, providing sensor redundancy for increased safety and reliability through HART communication alerts.

This unit features a compact housing with a diameter of 44mm and depth of 20.2mm, and can handle a maximum supply voltage of 300 volts DC. Its rugged design is well suited for use in hazardous areas certified for ATEX and other international standards including UL 61010 and IECEx for Zone 2 environments.

User-friendly installation is enabled by a large centre hole accommodating various probe mount diameters and loop test pins to verify current loop integrity without disruption. Visual status LEDs signal faults and transmitter health complying with NAMUR guidelines.

The device benefits from superior accuracy with a very low temperature coefficient, fast response time suitable for safety-critical applications, and high galvanic isolation (2.5 kVAC / 55 VAC) which protects the transmitter from electrical interference and ground loops. Runtime meters provide a history of process and ambient temperatures for process control monitoring.

Supports Relay output for control circuits. Wide input tolerance including thermocouples and RTDs. HART 5 and HART 7 communication protocols for easy integration. Robust isolation and protection against electrical disturbances.

Certified for hazardous areas including ATEX Zone 2 and IECEx Zone 2. Compact installation-friendly design with loop test pins and LED status indicators. Manufactured in Denmark to ensure quality and reliability.

This temperature transmitter is ideal for use in industrial automation, process control, laboratory systems, and hazardous area monitoring where reliable temperature measurement and conversion are critical. It is suited for industries such as chemical processing, oil and gas, manufacturing, and HVAC systems.
