As RTD elements are fragile, they are often housed in protective probes called thermowells. RTDs have higher accuracy and repeatability [a] than thermocouples, which is why they are slowly …

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

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 …

Select from a variety of RTD probes varying from surface probes to penetration probes. These probes are perfect if you’re requiring a higher standard of accuracy in your restaurant, lab, …

An RTD sensor is typically a length of wire made from a pure metal such as platinum, nickel, or copper. It is available either as a thin film sensor, where the wire is placed in a ceramic body, …

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 …

Choose from our selection of RTDs, including threaded RTD probes, thermocouple and RTD connection heads, and more. Same and Next Day Delivery.

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