2.6 Functional principle
The pendulum with the measuring mass is moved in the measuring direction by a force (acceleration,
inclination, vibration) acting in this direction. The movement of the measuring mass causes a change
of capacitance which is registered as primary measuring signal. The output signal (0,5 .. 4,5V) is
proportional to the deflection, thus to the acceleration. For inclination measuring the conversion from g
= 9.81 m/s

into angular degrees is a sine function. A sensor with small measuring range (+/-0,5g) has
a higher resolution than a sensor with large (+/-12g) measuring range.
