Miniature, OEM Inclinometer

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.
