SENSOR FOR MEASURING TENSION IN FLEXIBLE CONNECTIONS Russian patent published in 2007 - IPC G01L5/04 

FIELD: measuring equipment.

SUBSTANCE: sensor for measuring alternating tensions in flexible extended hydro-acoustic and seismic antennas contains a resilient plate with piezo-element, working on bending oscillations. Second such plate is introduced additionally, having piezo-element, and both plates are mounted symmetrically on ends of rigid rod, which connects centers of both plates mechanically. Rigid rings are connected to edges of each plate, meant for connecting the sensor to cover being researched. Piezo-elements of both plates are enabled correspondingly relatively to polarization direction. Apertures, having shape of a sector for example, are made in plates symmetrically relatively to plate centers.

EFFECT: possible measurement of longitudinal tensions in antenna covers, increased precision of measurements in presence of vibration and acoustic interferences and ensured passage of signal wires of antenna in question through the sensor.
