摘要

The functional testing device has a housing or housing part (8) with a connecting part or connecting winding part (7) for a thermostat valve head (12). An axially movable measuring spindle (13) lies on an actuating pin (19) of the thermostat valve head. An input signal of a temperature sensor and device evaluates an electronic circuit for measuring the axial position of the measuring spindle. An output signal is produced for displaying the functional capability of the thermostat valve head.
