PR Electronics 3331 Temperature Transmitter Temperature Input 300V dc, 70 °C, -25 °C

PR Electronics 3000 series temperature transmitters offer reliable and accurate conversion of industry process temperature signals to analogue or digital outputs. The easy DIP-switch set-up allows for more than 1000 different pre-calibrated temperature range combinations. The 3000 series are compact, fast, and easy to use. With a slim 6 mm housing that offers exceptional performance and EMC immunity for dedicated applications.
Designed and rated to operate between -25 ˚C to +70 ˚C, making these devices a good choice in applications where the ambient temperature changes greatly, for example in control panels mounted in outdoor locations. These transmitters have a low temperature coefficient achieving precise measurements, even when the panel is exposed to wide variations in ambient temperature. You can continue to rely on the output signal, with no need to re-calibrate your device.

• High basic 0.05% accuracy in all available signal ranges
• All units tested to ensure 2.5 kVAC isolation and have excellent noise immunity
• NAMUR NE21 burst A criteria
• Transmits rapid changes in process measurements to your PLC/DCS for fast and accurate monitoring of critical signals
• Response time of < 30 ms for temperature measurements
• Low temperature coefficient better than 0.01% / °C in a wide -25 to +70°C ambient temperature range for precise measurements
• Long term accuracy better than 0.1% / 3 years with no need for re-calibration

Re-calibration is not needed after changing the DIP-switch range settings. Just change the DIP-switch, cycle the power to the unit and obtain the new, pre-calibrated I/O range. HART programming is enabled for selected devices.

Devices can be mounted both vertically and horizontally with no air gap separation required. The devices snap onto a power rail or DIN rail and are easily detached by lifting the bottom lock.

Safe galvanic isolation of 2.5 kVAC provides high noise immunity and prevents ground loops for accurate delivery of the process signal to your control system.

A front LED indicates device status, e.g. an error in the set-up, sensor or hardware.

All terminals can withstand up to ±31.2 VDC and are protected against incorrect supply wiring to ensure safe, error-free installation.
