Screw-in sensors are used to protect electrical machines against thermal overload. KRIWAN screw-in sensors with the same or different nominal response temperatures can also be connected in series. This makes it possible to monitor different limit temperatures at low cost. KRIWAN screw-in sensors are characterized by a very steep R/T characteristic. The design is optimized for low thermal inertia.
