Sensors

The control technology as well as the sensor are part of the control circuit and are important components of a controlled system. Our product portfolio is now further enhanced with customer-specific sensor solutions. As well as the traditional thermocouple (TE) it also includes sheath thermocouples and resistance thermometers in accordance with DIN 43735 and DIN EN 43722.

Because every application has its particular requirements, there are no standardised TE solutions. We aim to offer you the right solution for your application.

Our particular performance features:

  • High-quality sensors Made in Germany – produced in accordance with DIN EN ISO 9001 / 14001
  • Exactly the right sensor for your application
  • Calibration to the highest level

Thermocouples and resistance thermometers are known as contact measurement devices, because in this process the measurement elements are in direct contact with the media whose temperature is to be recorded. The two processes are based however on different physical phenomena. The basis of the temperature measurement with thermocouple is the Seebeck effect. The process makes use of the physical phenomenon that the connection of different metals generates a voltage which varies with the temperature. The resulting thermal current can be used to determine the temperature.

The list of sectors and industries in which such sensors are used is proof that this type of temperature measurement is extremely widespread. The associated industries are particularly:

  • The glass industry
  • Industrial furnaces
  • The chemical industry
  • The aluminium and non-ferrous metal industry
  • Waste incineration
  • Systems and mechanical engineering
  • The food industry
  • The plastics industry

Thermocouples:

We supply thermocouples in different versions with metal or ceramic protective conduits, thermocouple and limit deviations in accordance with IEC / EN 60584-1.

In temperature measurement with thermocouples the measurement is carried out inside the element. To achieve as reliable a temperature measurement as possible with thermocouples, the medium to be measured and the measurement instrument must be at the same temperature. This fact poses one of the greatest challenges for the design of thermocouples. The element must be designed so that with the best-possible recording of the temperature in the respective measurement environment, economic operation plus long service life can be achieved.

By measurement of the electrical voltage, precise conclusions may be drawn about the temperature of the medium being measured. Metal or ceramic protective conduits are used for protection of the measurement elements. Which material to be used for protection depends on the ambient conditions. The two materials can also be combined. In other measurement environments it is also possible to dispense with the protection conduit. The thermocouple can then usually reach the ambient temperature and respond to changes more rapidly. It must nevertheless be remembered that without protection conduit, measurement is possible only at temperatures of 1100-1300 °C.

Sheath thermocouples in accordance with IEC / EN 61515

We supply flexible sheath thermocouples in accordance with IEC/EN 61515 in different versions: Thermocouples and limit deviations in accordance with IEC / EN 60581-1 and conductors in accordance with IEC / EN 60584-3
