Pressure transducer with piezoelectric crystal for harsh environment use |
摘要 |
A pressure transducer comprising a housing and a piezoelectric resonator in the housing, wherein the resonator is made of a piezoelectric crystal having Curie temperature greater than 1000° C. or having no Curie temperature up to its melting point greater than 1000° C., and the piezoelectric crystal has a piezoelectric constant more than two times greater than that of quartz. |
