Temperature sensor

Temperature sensors are electrical components that deliver an electrical signal that changes in the same way as the temperature. The temperature can be measured with or without contact with the medium being measured. An infra-red sensor is one example of a contactless temperature sensor. Temperature sensors that only measure temperature with contact are resistance thermometers and thermocouples.

If you should have any further questions, please contact us. Our many years of experience mean that we are experts at designing temperature sensors. We are therefore more than happy to help you when it comes to deciding which thermocouple to choose for your application. If you have any special requests, we can even develop customised products for you that are adapted to your measuring conditions. Find out more on our Customised solutions page.

Thermocouple vs. resistance thermometer

Resistance thermometers offer the advantage of greater accuracy compared to thermocouples.

Thermocouples, on the other hand, can be used at higher temperatures and offer better response times.

What are temperature sensors?

Temperature sensors are devices that are used to measure temperature changes in environments, systems or substances. They generate an electrical signal that is proportional to the change in temperature. This signal can then be analysed and interpreted to obtain an accurate temperature measurement.

In our range we offer different types of temperature sensors based on different principles and suitable for different applications.

Resistance thermometers

Resistance thermometers measure temperature by measuring the resistance of a metal (usually platinum), which changes with temperature. Resistance thermometers are known for their accuracy and stability over a wide temperature range and are often used in industrial and scientific applications.


Thermocouples are the other type of temperature sensor in our range. They consist of two different metals joined at one end. When the connected end is heated or cooled, a voltage is created that is proportional to the temperature difference between the connected end and the open end. Thermocouples are robust, inexpensive and can measure a wide temperature range, but they are not as accurate as resistance thermometers.

The role of temperature sensors in the automotive industry

Temperature sensors are indispensable components in the automotive industry. As a company specialising in the manufacture of temperature sensors, we are aware of the important role they play in modern vehicle technology. Temperature sensors make it possible to measure the temperature of engines, brakes or air conditioning systems and thus ensure optimum performance and safety.

Without precise temperature measurement, serious damage to the vehicle can occur. We therefore rely on the use of high-quality temperature sensors that enable accurate temperature measurement under all conditions.

Our many years of experience in the development and manufacture of temperature sensors have made us a leading supplier in this field.
