一、概述石英谐振器(简称晶体)已经成为现代电子技术中不可缺少的器件之一。石英谐振器中晶片的切型不同,频率温度特性也大不一样,其中频率温度系数大且线性好者,便可用来测量温度,这类晶体称为测温晶体。石英晶体温度计是通过测量测温晶体的谐振频率来测量温度。与电压、电流等模拟量相比,频率计量最容易实现高精度,所以,石英晶体温度计具有稳定度高,重现性好,牢固可靠,可远距离隔测,便于实现数字化等优点。因此,国外在六十年代已出现数字式石英晶体温度计。测温晶体所采用的晶片切型有一次转角的Y0°、Y+5o、Y+26°、Y-30°等,两次转角的有所谓“LC”(Lienear Coefncient)切型。在摄氏上百度的温度范围内,它们的频率温度 First, an overview Quartz resonator (referred to as the crystal) has become one of the indispensable devices in modern electronic technology. Quartz resonators in the different types of chips, the frequency of temperature characteristics are quite different, of which the frequency temperature coefficient and good linear, can be used to measure the temperature, this type of crystal called temperature crystal. Quartz crystal thermometer is measured by measuring the resonant frequency of crystal temperature measurement. Compared with voltage, current and other analog, the frequency measurement is the most easy to achieve high accuracy, so quartz crystal thermometer with high stability, good reproducibility, solid and reliable, distance measurement, easy to achieve the advantages of digital. Therefore, foreign countries in the sixties have appeared digital quartz crystal thermometer. Temperature crystal used in the chip cut has a corner of Y0 °, Y +5 o, Y +26 °, Y -30 ° and so on, the two corners of the so-called “LC” (Lienear Coefncient) type. In the Celsius Baidu over the temperature range, their frequency temperature
