History
For over 100 years Heraeus has with platinum temperature sensors accompanied the developments in the field of temperature measurement, improving and forming it with many important innovations. As one of the most important physical quantities, temperature affects the function of technical equipment as well as speed and selectivity in numerous industrial processes. Its exact measurement and control has therefore always been of great interest.
The increasing awareness of energy as a valuable resource has further increased this importance. Since 1997 Heraeus Sensor-Nite, a subsidiary of the Belgian Heraeus Electro-Nite, has been continuing the tradition of sensor production. In 2003 the company was renamed as Heraeus Sensor Technology GmbH. It produces and markets temperature sensors in platinum thin-film technology for the fields of automotive engineering, process technology, household appliances, heating, ventilation and air conditioning, life sciences and electronics.
