ABSTRACT:
Method for compensating an output signal of a photoelectric sensor having a drift due to aging a drift in temperature and a signal in absence of optical excitation (dark signal), in an electrical proportional remote control apparatus of the manipulation or analog type comprising an actuation member or actuation part for progressive displacement functionally associated to at least one photoelectric sensor adapted to generate an electrical signal of which one parameter is representative for the displacement and/or the position of said actuation member.
