a mechanism to reveal the various actions of inclination

摘要

Device suitable for detecting changes, however slow the may be, of inclination of a body (1), which the device is rigidly fixed to, relative to a plane, composed of a piezoelectric transducer (2), suitable to generate an electric signal proportional to said changes, and of an electronic circuit (3) including at least a very high input impedance amplifier circuit (3b), filtering circuits and a trigger circuit (3c) having adjustable threshold, suitable to eliminate the electric signals caused by vibrations of the body and to enable the electric signals caused by said changes of inclination to control automatic control and/or to actuate a warning device, when the change of inclination attains prefixed values
