PRECISION TRANSDUCERS USING MECHANICAL RESONATORS.

We have long focused on the outstanding characteristics of mechanical resonators and directed intensive research toward finding applications. This paper describes mainly the structure, principles, and characteristics of a double-ended tuning fork resonator which combines two tuning forks, cylindrical resonator which consists of a thinwalled cylinder fixed at both ends, and transducers using these mechanical resonators for pressure, force, and density measurement.
