一种音叉式水晶温度传感器

Tuning-Fork Quartz Temperature Sensor

研制成功一种水晶温度传感器。它采用ＺＹＴＷ１２０°／８．５°新切型，弯曲振动模式工作。封装尺寸是Φ３ｍｍ×８ｍｍ。测温范围宽－５５～２６０℃，准确度高（≤０．０２℃），分辨率好（≤０．０１℃），响应速度快（≤４ｓ），功耗低（≤２μＷ），长期稳定性佳（≤０．０１℃／年），不必使用Ａ／Ｄ变换器，直接与计算机配合使用。该传感器已成功地应用在ＷＹ－Ｊ１型精密水晶温度仪中，并在某国防工程应用，效果满意。

A new type of quartz temperature sensor has been developed.It uses a flexural vibrating tuning-fork mode and a new cut with the name ZYTW 120°/8.5°.Its overall demension of encapsulated sensor is  Φ3 mm×8 mm . The sensor operates over a wide range of temperature from -55 ～260 ℃.It has a higher precision better than 0.02 ℃,higher resolution than 0.01 ℃,higher response speed(≤4 s),small power consumption(≤2 μW) and better long-term-stability than 0.01 ℃/year.The sensor can be diretly used with a computer with A/D converter omitted. It has been successfully applied to hith precision instrument measuring temperature with the type WY-J1. The instrument has been applied to a national defense work.And it has been proved good.
