电阻应变计技术六十年(5) 电阻应变计在传感器技术中的应用(上)

Sixty years for Electric Resistance Strain Gage Techniques(5)

本文主要介绍电阻应变计在传感器中应用的一般情况,着重介绍目前应用最广的电阻应变式称重(测力)传感器和电阻应变计压力传感器的现状及展望。

The electric resistance strain gage has many uses in addition to the direct determination of strain, but it will bonded on the elastic body, the strain of elastic body will be linear with resistance change of strain gage. Reference is being made to the variety of devices which employ strain gages as the sensing element for measuring load, force, torque, pressure, displacement and other physical varieties. Such devices are commonly referred to as strain gage transducers. This article especially introduces many current application and prospects of strain gage cells and strain gage pressure transducers.
