一、简介电子数学测力仪(以下简称测力仪)是用力敏传感器对作用力进行受感传递,达到非电量与电量的转换,从而获得与被测介质的力成正比的直流电压模拟量输出。用超低漂集成运放,以差动放大电路形式对传感器输出的低电平信号精密放大。用数字电压面板表(液晶或数码管)显示,可直接读出被测力(kg)的数值(图1)。因此它集成度高,制作成本低,具有读数清晰、精度高、功耗低、重量轻、
I. INTRODUCTION Electronic mathematics dynamometer (hereinafter referred to as dynamometer) is a force-sensitive sensor that transmits the sensed force and achieves conversion of non-electrical quantity and electric quantity, thereby obtaining a direct-current voltage analog quantity proportional to the force of the measured medium. Output. With the ultra-low drift integrated op amp, the low-level signal output by the sensor is precisely amplified in the form of a differential amplifier circuit. With the digital voltage panel meter (liquid crystal or digital tube) display, the measured force (kg) can be read directly (Figure 1). Therefore, it has high integration, low production cost, clear reading, high precision, low power consumption, and light weight.
