Kruff has a wide range of insert sensors and core temperature probes, with varying temperature ranges (thermocouple type K) from -50°C up to +1150°C, depending on which sensor you need for your freezer and cooling cabinets. The insert sensor is usually placed directly in the process flow to measure the exact temperature at the exact location where you want to get the data. Plug-in sensors are available in various resistances, for example PTC, NTC, PT100, PT1000 and TcJ.
