  • Magnetically driven resonant disc pressure transducer
    Patent number: 5325719
    Abstract: A vibrating disc transducer assembly suitable for accurately measuring high pressures utilizes a transducer having a vibratory disc that is preferably fabricated from silicon and excited to vibrate in the thickness-shear mode. The excitation is accomplished by placing the resonator in a magnetic field and passing an electric current through electrodes on opposite sides of the disc. The transducer is supported in a housing that communicates with the medium whose pressure is being measured.
