力传感器是把力转换成电信号的一种装置。在机械测量中,主要用来测量拉力、压力等等。荷重(力)传感器中,使用最多的是应变式传感器,此外,还有压电式传感器、压磁式传感器及电容式传感器等等。本讲主要介绍应变式荷重(力)传感器。荷重(力)传感器的关键部件是弹性元件,弹性元件的好坏,直接影响传感器的质量。荷重(力)传感器用得最多的弹性元件即应变片,因此,我们首先讲一下应变片的原理。
A force sensor is a device that converts force into electrical signals. In mechanical measurement, mainly used to measure tension, pressure and so on. Load (force) sensors, the most used is the strain sensor, in addition, there are piezoelectric sensors, pressure sensors and capacitive sensors and so on. This talk mainly introduces the strain load (force) sensor. Load (force) sensor is the key component of elastic components, the quality of elastic components, a direct impact on the quality of the sensor. Load (force) sensor with the most flexible element that is strain gauge, so we first talk about the principle of strain gauge.
