KRIWAN screw-in sensors are used to protect electric motors against thermal overload and overheating. The screw-in sensor is screwed into the cylinder head, for example, and detects the temperature of liquid or gaseous media. The stainless steel enclosure protects the temperature sensor from environmental influences, such as aggressive media and mechanical stress.
