Speel´s SACC-2440 is a 3-axis accelerometer, which is intended to sense accelerations of the aircraft in the longitudinal, lateral and vertical axes.

It shall be placed close to the center of gravity point of the aircraft.

The output circuitry of the unit is equipped with low pass filters to avoid distortion of the signal caused by vibrations.

The filters of the unit remove higher frequency components of the signal that are not related to the aircraft motion as well as arrange output sensitivity of the unit.
