一、现状图1表明四种测力传感器及其所属的初级电子装置和次级电子装置。为了说明测力技术的现状,下面讨论这四类传感器及其初级电子装置。1.电阻应变片测力传感器二十多年来的发展已经取得了满足工业 First, the status quo Figure 1 shows the four kinds of load cells and their associated primary and secondary electronic devices. In order to illustrate the status quo of force measurement technology, the following discussion of these four types of sensors and their primary electronic devices. 1. Resistance Strain Gauge Load cell sensors have been developed for more than two decades to satisfy the industry
