Cylindrical vibrator type pressure transducer

摘要

A pressure gauge for determining the pressure applied to a cylindrical vibrator by measuring the resonance frequency of the vibrator. The vibrator comprises a thin-wall cylindrical portion, a thick wall cylindrical portion extending from one end of the thin wall cylindrical portion and a thick wall end portion joined to the end of the thin wall cylindrical portion. The thin wall cylindrical portion is installed within a cover, to which the thick wall end portion is securely attached. The inventive vibrator type pressure gauge produces greater accuracy and reliability while also being resistant to external vibrations and pressures.
