PR Electronics Temperature Transmitter 31.2V dc, -25°C to 70°C Operating Range Model 3111

PR Electronics 3111 Temperature Transmitter is a high-precision, analogue current output device designed for converting process temperature signals across a broad input range from -180°C up to 1372°C. It operates with a maximum supply voltage of 31.2V dc and is designed for ambient temperatures ranging from -25°C to 70°C, making it suitable for varying industrial environments.

This transmitter features a slim 6 mm housing providing exceptional performance and electromagnetic compatibility immunity, ideal for installation in control panels including those located outdoors. Its low temperature coefficient and high basic accuracy of 0.05% ensure precise measurements even during significant ambient temperature fluctuations.

Equipped with a DIP-switch interface, it supports easy configuration with over 1000 pre-calibrated temperature ranges, allowing flexible adaptation to various temperature sensors. After adjusting the DIP-switch, no re-calibration is required; a simple power cycle enables the new settings.

The device offers galvanic isolation up to 2.5 kVAC to prevent ground loops and interference, guaranteeing reliable delivery of accurate temperature signals to PLCs or DCS systems. It features a rapid response time of less than 30 milliseconds and complies with NAMUR NE21 burst A criteria for disturbance immunity.

Mounting on DIN rails is simple and secure with snap-on capability and no need for air gap separation, supporting both vertical and horizontal orientations. A front panel LED provides visual status and fault indication to facilitate quick diagnostics.

This product is certified for use in hazardous areas with Ex and ATEX approvals and complies with a variety of international standards including 2014/30/EU, TR-CU 020/2011, and 2011/65/EU. Manufactured in Denmark, it reflects high quality engineering suitable for industrial process control applications.
