Thermocouple
A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. The voltage can then be interpreted to calculate the temperature.

The standard covers the eight specified and most commonly used thermocouples, referring to their internationally recognized alpha character type designation & providing the full reference tables for each. These thermocouple types (Types K, J, N, T, E, B, R and S ) can be subdivided in 2 groups, base metal thermocouple and noble metal thermocouple.

Resistance Temperature Detector (RTD)
An RTD, also known as a resistance thermometer, measures temperature by correlating the resistance of the RTD element with temperature. An RTD consists of a film or, for greater accuracy, a wire wrapped around a ceramic or glass core. The most accurate RTDs are made using platinum but lower cost RTDs can be made from nickel or copper. However, nickel and copper are not as stable or repeatable. Platinum RTDs offer a fairly linear output that is highly accurate (0.1 to 1 °C) across -200 to 600 °C. While providing the greatest accuracy, RTDs also tend to be the most expensive of temperature sensors.
Resistance thermometers may be called RTD’s (Resistance Temperature Detectors), PRT’s (Platinum
Resistance Thermometers), or SPRT’s (Standard Platinum Resistance Thermometers).

Thermistor
A thermistor is a device whose electrical resistance is controlled by temperature. Thermistors are available in two types: NTC thermistors, or negative thermal coefficient thermistors, and PTC thermistors, or positive thermal coefficient thermistors. In NTC thermistors, the resistance decreases proportionally with increases in temperature. PTC thermistors, on the other hand, have increasing resistance with increasing temperature.

NTC sensors are typically used in a range from −55°C to 200°C. Most PTC thermistors are designed to operate with a transition temperature somewhere between 60°C and 120°C, however, devices can be manufactured that can switch as low as 0°C or as high as 200°C.

We manufacture and supply a full range of temperature sensors. If you can’t find what you are looking for below, get in touch with us. We can help you identify your broken sensors or help design sensors for new applications.

Call us to discuss how we can meet your individual needs.
