Abstract:
1. A tiltsensor comprising: a) a closed spirit level curved over an angle of up to 360° and containing an electrolytic liquid and a gas bubble; b) a plurality of electrode configurations for sensing the position of the gas bubble and thus the tilt angle of the tiltsensor, wherein each of the plurality of electrode configurations has a plurality of electrodes and each of the plurality of electrode configurations are arranged along the spirit level, and wherein the electrodes are in electric contact with the electrolytic liquid; and c) a first electronic circuit to which the electrodes are connected for measuring electric quantities between selected electrodes, wherein the electrode configurations are arranged in succession along the spirit level and are arranged offset to each other at fixed angles such that the tilt angle measuring ranges associated with the electrode configurations overlap one another, in a seamless manner.
