Thermal protection of electric machines. The PT100 screw-in sensor is used for measuring the temperature in electric machines and has been specifically designed for thermal protection of machines in conjunction with KRIWAN motor protectors.
The PT100 is screwed into the motor housing. If the temperature increases, the PTC becomes highly resistive and, in conjunction with a KRIWAN motor protector, switches off the motor when the rated shut-off temperature (NAT) is reached.
