A miniature digital temperature sensor with the ZY cut quartz crystal tuning fork resonators was developed. The quartz crystal tuning fork resonators have the characteristic that the resonance frequency changes by the external temperature, which achieves high sensitivity and high-speed response and frequency stability by a sample structure. The quartz crystal tuning fork resonators are square cross...
This paper describes a novel quartz tuning fork temperature sensor, the principle of the quartz tuning fork temperature sensor is to detect resonance frequency shift by an external temperature. It has such advantages: high sensitivity, high accuracy, and good long-term stability. The temperature sensor is prepared of synthetic quartz on ZY-cut plates and configured by ZY-Cut quartz crystal wafer based...
A novel high-performance sensor technology for measuring and monitoring temperature is described. This type of temperature sensor using a quartz tuning fork resonator is inherently insensitive to noise because the output is a frequency shift cause by an external temperature. The output can easily be converted into a digital signal and directly connected to a microcontroller without an A-D converter...
Piezoelectric resonators have widely been utilized not only for time keeping devices but also for temperature measurement sensors. In order to obtain a temperature sensor having low power consumption, low cost, fast response, high sensitivity and high precision, resonance frequency of quartz tuning fork crystal for use in temperature sensor was analyzed by the finite element method (FEM). FEM was...
