目前常用的各种测量静态和动态荷重的传感器一般都采用电阻式荷重传感器。这种传感器虽具有灵敏度高,线性好等优点,但在实际应用中也遇到抗超载能力差,对使用环境温度要求较高,容易给相应的放大装置引进电干扰等缺点。为此我们利用QGD—100型气动定值器自制了一种气动荷重传感器,代替BHR型电阻式荷重传感器在皮带 The current commonly used to measure static and dynamic load sensors are generally used resistive load cell. Although this kind of sensor has the advantages of high sensitivity, good linearity and so on, it also encounters the shortcomings of poor anti-overloading ability, high requirement on the use environment temperature and easy introduction of electrical interference to the corresponding amplifying device in practical applications. To this end we use QGD-100-type pneumatic setter made a pneumatic load sensor, instead of BHR-type resistive load cell in the belt
