FIELD: measurement of parameters of vertical oscillations. SUBSTANCE: the effect of self-orientation in the device is attained due to the fact that piezoelectric sphere 2, serving as a sensitive element and containing spherical inertial mass 1 and damping liquid 7 inside it, is symmetrically and with a constant clearance secured on flexible supports 4 in rigid body 3. The output signal is picked off the inner cover of the sphere and body, to this end, use is made of a small amount of current-conducting non-wetting liquid 5 positioned between the sphere and body. EFFECT: non-sensitivity of seismic transducer to horizontal component of acceleration, thus obtaining the effect of self-orientation. 2 cl, 1 dwg
