Reotemp Resistance Temperature Detectors

Reotemp RTDs (Resistance Temperature Detectors) are electrical temperature sensors that determine temperature by measuring predictable changes in electrical resistance.

Most modern industrial Reotemp RTDs use platinum as the resistive element, with nickel and copper types also available for legacy and specialized sensor requirements.

Reotemp offers RTDs in multiple sensor, assembly, and wiring configurations for a range of temperature measurement requirements.

Standard and extended temperature ranges are available, along with multiple platinum RTD tolerance classes and optional Hi-Accuracy™ and Hi-Vibe™ constructions on applicable sensors.
