摘　　要：宽度弯曲模式音叉热敏新切型的新型水晶温度传感器具有高准确度、高稳定性、超高分辨力等优良特征。经测试，其分辨力可达10^-3-10^-5℃，灵敏度远远高于绝大多数温度传感器和温度计；其长期稳定性在1年内可达0．001～0．01℃。由于水晶温度传感器的输出是频率信号，抗干扰能力强（干扰信号可高达25db以上）。配有RS485接口标准组成的局域网，可方便地构成远传及联网结构，解决了高精度区域性测试的难题。因此，在气象和海水温度测试中。具有广泛的应用前景。A new cutting type crystal temperature sensor, which adopts the width flexural mode, has a high accuracy ,long-term stability and excellent resolving power. Tests show that its high resolving power can reach 10^-3 to 10^-5℃, senstive is for hisher than most temperature sensor and thermometer and that the long-term stability can reach 0.001 to 0.01℃ within a year. The greatest advantage is that its output is frequency signals,which can improve the anti-interference ability （interfering signal up to 25db）. Connected with the RS485 standard interface, the sensor can be formed onto a far transmitting network conveniently, thus solving the test region problem with high accuracy. Therefore, the sensor has wide application in the field Of meteromlogical and sea-water temperature tests.
