Product overview temperature sensor technology

Our temperature sensors are high-quality products, which are characterized by high processing quality, durability and precision. Individual solutions are a matter of course for us, meaning that we adapt or redesign all products to your requirements. You receive a product that is optimally adapted to your needs, thus unfolding its full capacity in use. The use of high-quality materials and our company-wide certified and monitored processes ensure consistent quality that meets your requirements.
If your application involves challenging conditions, such as aggressive acids, vapors, melts, coatings, or extremely low or high temperatures, you’ve come to the right place. Should your application involve confined spaces or other structurally complex conditions, we can also provide tailored solutions for this area. Naturally, we offer suitable accessories for all sensors we manufacture, including connectors, thermowells, and thread adapters. Upon request, we can also provide customized solutions in the accessories segment.
