NS-25/C2

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.
