<p>Filling level indicator has a rotary transmitter connected to a display shaft (8). A disc (23), made from a material that influences magnetic or electrical field, is on the shaft. Disc radius changes based on shaft angle, so that its frontal contour deviates from circuit-form. A sensor is in a display part, so that its active functional area is directed to the contour, to form an air gap between the sensor and the disc. The air gap is dependant on the respective position of the disc.</p> |
