Hot wire temperature regulating device for aerodynamic defrosting probe, has interrupter connected to hot wire and interrupter control unit, and other control unit with operational amplifier to control commutation time of commutator

摘要

The device has an electronic interrupter (SW) connected in series with a hot wire (RH) and an electronic interrupter control unit. Another control unit (4) including an operational amplifier (A1) controls a commutation time of an electronic commutator. The amplifier has an entry connected to wire and interrupter, another entry to receive consigned tension, and an exit (9) to open and close the interrupter. An Independent claim is also included for a unit measuring the temperature of the hot wire.
