These include sensor type, manufacturer, measurement range, body style, and more. And if you'd like to ask any questions, it's easy to get in touch with our friendly team.

What are temperature sensors?

Each temperature sensor is a device that can be used to measure, monitor, and regulate temperature. While most household devices only need to be ambient air temperature sensors, industrial and commercial applications are much more complex.

At RS, we stock sensors capable of measuring air, liquid, solid, and surface temperatures, along with those capable of detecting additional parameters like humidity.

Which temperature sensors are available?

We understand that no two applications are the same, so we provide a selection of thermal sensors to cater to a wide range of settings. Whether you need a temperature gauge for commercial food production or mechanical engineering, we only stock brands we know and trust to bring you fast, accurate, and reliable measurements.

We aim to keep the most popular models in stock, but we also update our entire range regularly. Among some of the latest temperature sensors, our online selection includes:

Infrared thermometers

Our selection of infrared temperature detectors enables contactless measurement and monitoring. While many thermal sensors rely on wired connections or probes, invisible infrared technologies are used in these versatile temperature sensors.

We stock high-quality models manufactured by brands like Banner Engineering, offered with both remote and wireless connectivity.

Infrared thermometers are suitable for use in environments where it might be difficult to reach an object or making contact could be hazardous. They are therefore frequently used in manual temperature checks by trade professionals like electricians, mechanics, firefighters, and heating engineers.

Thermocouples

We also offer an extensive range of thermocouples. Used solely as temperature sensors, these devices comprise two different types of metal joined at one end. A voltage is created when this junction heats up or cools down and this can be interpreted as a temperature.

Thermocouples are integral devices used in power generation, automotives, and many more applications.

Wireless temperature sensors

We also supply temperature-detecting devices designed to work without exterior wires, making them easier to install. Wall-mounted temperature transmitters like those by Dwyer Instruments offer convenient temperature monitoring in a durable, compact unit.

RTD sensors

Resistance temperature detectors are thermal sensors that contain a resistor. Unlike conventional types of air temperature sensors, they work with changes in resistance that correspond to temperature. As temperature increases, so too does resistance.

This relationship is both reliable and repeatable over time, making RTD temperature sensors a popular choice for operational applications in food processing, chemical monitoring, and industrial heating systems.

NTC Thermistors

NTC thermistors are sensors that exhibit a large change in resistance with a change in temperature. NTC stands for "negative temperature coefficient". They provide an easy to process analog signal that is well suited for temperature measurement, control, and compensation.

Temperature probes

Available in a range of physical formats, probes are elongated temperature sensors adapted for use in specific industrial applications. Various probe types can be used for surface, immersion, and interior temperature checks, so they're not limited solely to monitoring air temperature.

We stock RTD probes, NTC thermistor probes, humidity probes, and many more specialized models too. Many of our temperature probes are manufactured by Amphenol Advanced Sensors, but we're sure that you'll find the item to suit your requirements here.
