ABSTRACT:
In a method for converting an analogue measurement indication into electric signals, the angle of rotation of the pointer of an analogue display is contact free detected and converted into a proportional electrical output signal. This is achieved by using an application-specific integrated circuit having a Hall sensor which can detect the magnetic flux density parallel to the surface of the integrated circuit.
