MULTICOMPONENT POWER ACTION DETECTOR Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: detector can be used for testing transportation vehicles, control and alarm systems. Detector has shallow case, first and second elastic member and elastic members' relative displacement transducers. One end of first elastic member is tightly fastened to the case; the other end is made movable. Elastic member has shallow cavity inside which movable member is housed which is tightly connected with movable end of first elastic member. Second elastic member is made in form of membrane which has center to receive power action. Second elastic member is connected with movable end of first elastic member to form cavity between them. First to fourth relative displacement transducers are mounted pairwise in mutually perpendicular planes crossing central axis of first elastic member - between motionless end of first elastic member and free end of movable member. Fifth to eighth relative displacement transducers are mounted between case and movable end of first elastic member; the transducers are placed pairwise in mutually perpendicular planes crossing mentioned central axis. The ninth relative displacement transducer is mounted inside cavity between movable end of first elastic member and second elastic member at central part of membrane.

EFFECT: improved precision of measurement; reduced sizes; reduced number of detectors used for measurements.
