DEVICE FOR DETERMINING MONTAGE RESONANCE FREQUENCY IN PIEZO-ELECTRIC TRANSDUCERS

摘要

electronic engineering. SUBSTANCE: device has alternating frequency voltage generator, capacitor bridge with socket for connecting transducer, balancing members and recorder unit. Bridge shoulder adjacent to the transducer is manufactured as capacitor from piezo-ceramic material having no resonance properties in the frequency band of interest. EFFECT: larger set of transducers treated without applying mechanical excitation; high accuracy of operation. 2 dwg
