PR 3102 Pt100 Temperature Converter

The PR 3102 Pt100 temperature converter is a high-performance temperature signal conditioner engineered for precision and reliability in industrial environments. It accurately measures standard 2-, 3-, or 4-wire Pt100 RTD sensors and converts the temperature resistance into a clean, proportional analog current or voltage output for process control, monitoring, or automation systems. With conversion accuracy better than 0.1 % of span, the 3102 delivers dependable measurement fidelity you can trust.

The 3102 temperature converter, from PR electronics, measures a standard 2-, 3- or 4-wire Pt100 temperature sensor, and provides an analog voltage or current output. This Pt100 temperature converter can mount in the safe area or in Zone 2 / Division 2 hazardous areas. Furthermore, it features approval for marine applications.

• Temperature converter which measures a standard 2-, 3- or 4-wire Pt100 temperature sensor, and provides an analog current or voltage output signal.
• All terminals offer protection from over-voltage, polarity, and short-circuit.
• The 3102 Pt100 temperature converter can mount in Safe area or in Zone 2 / Division 2 areas and features approval for marine applications.
