Measuring the incidence angle of a peizoelectric transducer using a CO-3 calibration block
Source abstract
Abstract
A technique of using a CO-3 calibration block for measuring not only the base of a piezoelectric transducer (PET) but also its incidence angle is proposed. This approach allows a single specimen to be used in an automated PET certification system for obtaining its main characteristics. The results of measuring the PET incidence angle in an automated mode on a CO-3 block are compared with the measurement results on CO-2 according to GOST (State Standard) 14782–86. It is shown that systematic error is absent. The use of a CO-3 block substantially reduces the time of obtaining the basic characteristics of a PET and simplifies the calibration procedure.
