The model SC15 temperature limiter is a thermometer with a remote capillary for on-site display. Switch contacts ensure the simultaneous monitoring of limit values. This limits the temperature over or under a defined value. For this, the switching temperature can either be set via a knob on the window or is already fixed at the factory.

The shifting disk, which is arranged on the pointer shaft, actuates the switching operation at the microswitch when reaching the set switch point.
