高精度的石英晶体测温:
通常,我们都在使用如热电偶,热电阻,热敏电阻,半导体或集成电路传感器....来测量温度,实际上,如果利用晶体来做温度传感器,其精度就会大幅度提高!
石英晶体的振荡频率会随温度的变化而发生微小的变化，利用这一特性，通过测量石英晶体振荡器的频率，就可司接测得相应的温度值，所以石英晶体谐振器还可用来进行温度的测量。测温石英晶体谐振器就属于这一类产品，它采用玻璃外壳封装软弓线电极，分辨率可达0.01℃-0·0001℃，适合作测温敏感元件。
这里给出的一份文件,摘录有从网络或书籍的有关晶体测温的基本介绍,供朋友们参考!同时,感谢有关网站与原书籍作者的宝贵资料! ------ 期望这种方法可以普及和更广泛的获得实际应用!
(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,)
