微梁传感器是一种微米级别的传感器,利用双材料梁的温变效应进行测量,当环境的温度发生变化时,由于两种材料热膨胀系数的不同而产生弯曲变形,测量此变形即可实现对温度的传感。微梁传感器对比传统铂电阻温度传感器具有精度更高的优点,利用该传感器设计一种高精度井温仪,有望在温度试井方面发挥作用。针对应用于存储式井温仪上的微梁温度传感器进行了优化设计,通过室内实验验证了其可行性。 Micro-beam sensor is a micro-level sensor, the use of dual-material beam temperature-dependent effect of measurement, when the environment temperature changes, due to the two materials with different thermal expansion coefficient of bending deformation, measuring the deformation can be achieved Sensing of temperature. Compared with the traditional platinum resistance temperature sensor, the micro-beam sensor has the advantages of higher accuracy. Using the sensor to design a high-precision well temperature gauge, it is expected to play a role in temperature well testing. The micro-beam temperature sensor applied to the storage well temperature instrument is optimized, and its feasibility is verified through laboratory experiments.
