Description: High-precision quartz crystal thermometry:
Usually, we use such as Thermocouple, RTD, thermistor, semiconductor or integrated circuit sensor .... to measure the temperature, in fact, if you use the crystal to do the temperature sensor, its accuracy will be greatly improved!
Quartz crystal oscillator frequency variation with temperature and small changes, the use of this feature, by measuring the frequency of the quartz crystal oscillator, can the Secretary then measured the corresponding temperature value, so the quartz crystal resonator can also be used to the measurement of the temperature. The measured temperature quartz crystal resonator belongs to this type of product, which uses glass shell package soft arch wire electrode with a resolution of up to 0.01 ℃-0 · 0001 ° C, suitable for temperature sensitive components.
Given here a document, extract a basic introduction to the crystal temperature from the network or books for friends as a reference! The same time,
