In order to be able to accurately determine the inclination of machinery or machinery components, tecsis now has a wide range of inclination sensors. The sensors operate using a dielectric liquid, the surface of which always aligns itself horizontally by means of gravity, similarly to a spirit level. The liquid is located between two circular electrodes, one of which is divided into two semicircles. The space between them is half-filled with the liquid. When the sensor rotates, the capacities between the two semicircular electrodes at one side and the counter-electrode at the other side change.
