一、引言 在设计与应用高精度力传感器相匹配的各种数字式指示仪时,常常会遇到一个突出的难题;即仪表要求输入信号大,而高精度力传感器却是低水平的输出信号这种不相适应情况,要增大力传感器的输出信号;不单与加载时对弹性体的应变程度有关(这种应变由电桥电路输出来表示);而且也与电源电压对力传感器的各种参数
I. INTRODUCTION In the design and application of high-precision force sensors to match a variety of digital indicators, they often encounter a prominent problem; the instrument requires input signal, and high-precision force sensor is a low-level output signal This does not adapt to the situation, to increase the output signal of the force sensor; not only with the load on the degree of strain on the elastomer (this strain by the bridge circuit output to represent); but also with the power supply voltage sensor parameter
