Abstract
The disclosure relates to a system and method whereby bimetallic discs as well as a completed thermostat can be dynamically tested non-destructively. The bimetallic disc can be tested by utilizing its magnetic properties, the magnetic properties of the disc being sensed by a magnetic transducer under operating conditions to provide a velocity curve of disc movement. The thermostat is tested in the same manner as the disc with simultaneous monitoring of the electrical switch controlled by the disc to insure operation thereof at the ideal point on the disc velocity curve.
