FIELD: measurement of force pulses in rails, beams, bridges, forces in walls of bridged-over buildings, in power plants. SUBSTANCE: force transducer includes housing incorporating base, piezoelectric discs with holes, current collector with electric lead-out, fork-shaped holder made in one of end faces of base, each its br having hole, studs, bearing and adjusting nuts. Current collector with electric lead-out is installed between piezoelectric discs which are anchored between bars of fork-shaped holder with the help of studs put into holes of bars and piezoelectric discs. Outer surfaces of housing and bars have protrusions. The other end face of bottom is pressed with bearing nut against groove made in housing. Protrusions of bars contact inner surface of housing, protrusions of housing made cone-shaped and contact ring protrusion of mounting seat fabricated in the form of hole in examined object where force transducer is placed with preliminary compression force with the aid of adjusting nut. EFFECT: expanded application field of force transducer. 2 dwge
