一、前言近年来在许多科研、生产部门,对载荷、压力、力等参数的测定,广泛采用了以应变计为敏感元件的应变式传感器。实践证明,应变式传感器结构简单,精度和灵敏度较高而成本低。因此,它越来越多的被人们采用。可以预计,今后对于一般的力、压力等参数的测定,应变式传感器有取代其它种传感器的趋势。
I. Preface In recent years, many scientific research and production departments have widely adopted strain sensors with strain gauges as sensitive components for the determination of load, pressure, force and other parameters. Practice has proved that the strain gauge sensor structure is simple, high precision and sensitivity and low cost. Therefore, it is more and more adopted by people. It can be expected that in the future for the general determination of the force, pressure and other parameters, the strain gauge sensor has the tendency to replace other types of sensors.
