FIELD: instrument engineering.
SUBSTANCE: multiplexer acoustic array includes flat parallel plate out of pieso-electric crystal with crystallographic axis lying in the plate plane and passing through conditional plate center, interdigital transducers positioned symmetrically in pairs at the work side of plate and forming acoustic channel system where directions of acoustic wave propagation intersect in the conditional plate center where a circular zone is made in the conditional plate center for a sample, acoustic channels can excite plate-shape mode family of vibrations in the plate, with wavelength not exceeding plate thickness.
EFFECT: enhanced selectivity of vibration modes with increase of number of sensors for excited modes.
