Inclinometer NS-25/DQL2-IXA Theory of Operation: The NS-25/DQL2-IXA is a small, biaxial inclinometer for OEM use. It consists of an NS-25/C2 tilt sensor and conditioning electronics that provides complete electronic biasing and readout. The system is carefully designed to minimize drift and temperature effects. The sensor works in the way that an electrolytic 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.
