Inclination sensor NS-25/C2 Low cost, Tilt Sensor Theory of Operation: The NS-25/C2 is a biaxial, tilt sensor. The sensor works in the way that an electrolytical fluid is formed out by applying an AC-voltage on the planar electrode structures. When the sensor is tilted, the fluid level over the different electrodes and, in consequence, the conductance of the stray field is changed. Using a difference measurement principle, the tilt angle and the tilt direction can be measured. This sensor requires a separate conditioning circuit.
