Acoustic Resonances in Helium Fluids Excited by Quartz Tuning Forks

Journal of Low Temperature Physics, 2010
Ordinary quartz tuning fork resonators, operated at about 30 or 200 kHz frequency, couple to acoustic first and second sound resonances in helium fluids under certain conditions. We have studied acoustic resonances in supercritical 4He, normal and superfluid 4He, and in isotopic mixtures of helium.

Air and gas damping of quartz tuning forks

Sensors and Actuators, 1983
Abstract The effects of air and gas pressure on the vibration of miniature quartz tuning forks are investigated. Beside damping, which decrease the Q factor of the resonator, the resonant frequency appears to vary quite linearly with the gas pressure. This basic effect could lead to the realization of a simple pressure sensing element. Analysis of

A study of quartz tuning fork resonators in the overtone mode

Proceedings of IEEE 48th Annual Symposium on Frequency Control, 2002
Quartz tuning fork resonators in the overtone mode have been studied in less detail than those in the fundamental mode. We discuss the characteristics and optimal design to put them into practical use. >

Standoff LITES Sensor Based on a Frequency‐Stabilized Encased Quartz Tuning Fork

Laser & Photonics Reviews
We propose and demonstrate a standoff light‐induced thermoelastic spectroscopy (standoff‐LITES) sensor for the first time. An encased quartz tuning fork (QTF) was employed in the standoff‐LITES sensor to improve the frequency stability.
