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.
Claims15
A method for converting an analogue measurement indication into electric signals, comprising the steps of:
- positioning an application-specific integrated circuit having a Hall sensor which is adapted to detect a magnetic flux density parallel to the surface of the integrated circuit, the Hall sensor being disposed parallel to the plane of rotation and above the rotational axis of a pointer of the analogue rotational display of a gauge, the pointer supporting a magnet;
- measuring the angle of rotation of the magnet by the application-specific integrated circuit having the Hall sensor;
- and
- outputting an electric signal in accordance with the angle of rotation of the magnet.
