Piezoelectric transducers for high temperature measurements

摘要

The invention relates to measuring devices and is designed to work in vibration and pressure sensors.; The piezoelectric transducer comprises two zhestkosoedinennye piezoelectric plate and a base made of piezoceramic plates with identical material in the form of a hollow cylinder, which is fixedly connected to one of piezoceramic plates.; Piezoceramic plates have electrodes whose radius is in the range from 0.6 to 0.7 times the inner radius of the base.; The device has the ability to operate at high temperatures and can be used in aerospace technology.
