THERMORESISTANCES

The functioning principle of a thermoresistance is the following: as the temperature varies, its resistance varies too and the magnitude of this variation can be correlated to the temperature variation.

PRECISION AND QUALITY
The type of materials used to make the probe, its physical shape as well as the type of temperature sensor are the elements that confer the final product the required characteristics for its further use. There are several qualities of sensors –the most accurate being the most expensive. Therefore, we will choose one or another sensor depending on the clients’ actual needs. One should also take into account that each sensor has an optimal measuring range on which the price/quality ratio depends. For example, in the sector of industrial cold, PTC, NTC or PT1000 sensors are most commonly used, whereas in the sector of laboratories and counter-expertise, Pt100 are the most common. In the housing technology and air conditioning sectors, NTC sensors are most often used. Generally speaking, nearly all types of sensors are employed in the production of machine tools, depending on the above-mentioned general characteristics.

SPECIAL USE
The standardisation of thermoresistances in conformity with DIN 43760 induced a certain amount of standard designs. However, it is often necessary to adapt the temperature probe to each case in its shape and dimensions. Our thermoresistances are made with Pt100 resistances in conformity with DIN 43760.
