General of the inclinometer system

4.1 Description of the liquid/conductive measurement principle

Platinum electrodes are deposited in pairs on the base of the sensor's cell parallel to the sensitive
axis. The chamber is partially filled with an electrolytic liquid. When an alternating voltage is passed
between two electrodes, the electric current will create a dispersed field. By tilting the sensor and
thereby reducing the level of liquid, it is possible to confine this stray field. Because of the constant,
specific conductivity of the electrolytes a variance of resistance is formed in relation to the liquid level.
A basic differential principle will yield an angle of inclination from the polarity signs.
