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 adverse operating conditions, such as aggressive acids, vapors, melt, coatings, or very low or high temperatures, you have come to the right place. If cramped conditions or other structurally complex conditions prevail within your application, we can offer you solutions in this area as well. Of course, we provide associated accessories such as connectors, thermowells and thread adapters for all sensors we produce. We also offer special solutions in the accessories sector on request.
