For a longer service life than thermocouple probes and more consistent readings over time, these thermometers have a resistance temperature detector (RTD) probe.

The RTD wire is typically platinum (Pt), nickel (Ni), or copper (Cu). The material has an accurate temperature–resistance relationship which is used to provide an indication of temperature.

An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases.

RTDs, or resistance temperature detectors, are sensors used to measure temperature. These sensors are the among the most accurate temperature sensors available, covering large …

RTD probes with lead wires provide accurate temperature monitoring for industrial, scientific, and HVAC applications. Durable and reliable, they ensure precise measurements in demanding …

Each probe is individually calibrated and includes an accredited report of calibration from the manufacturer. This RTD temperature probe is an excellent value for a precision thermometer.

Probes, Sensors or elements used to measure temperature by correlating the resistance of the RTD element with temperature.

Littelfuse manufactures an extensive selection of Resistance Temperature Detector (RTD) probes and assemblies that are invaluable for sensing temperature in many industrial applications.

RTD stands for Resistance Temperature Detector. It’s a sensor used to measure temperature by detecting changes in electrical resistance of a metal element as temperature varies. Core …
