We know in a variety of weighing and measuring products, in order to ensure the accuracy of measurement performance, choose what structure of the weighing sensor, what specifications of the weighing sensor. It seems to be very important. The advantages of the cylindrical weighing sensor are compact structure, strong overload capacity, high natural frequency and fast dynamic response, easy installation and low manufacturing cost. But there will be some problems when we use it. Today we will share with you the use of the column weighing sensor in the truck scale.
Because of the above advantages, the cylindrical weighing sensor is widely used in truck scale, but its disadvantages can not be avoided. In view of the poor lateral and eccentric load resistance of cylindrical weighing transducers, the eccentric load angle which does not affect the metering performance is specially recommended on some product samples of some companies. The limit of the eccentric load angle is tension structure, so that the load-bearing device is basically in a state of no movement in the horizontal state, while ensuring that it does not affect the vertical force. Use. The truck scale has a relatively large bearing length, and the limit device is allowed to have a certain displacement in the horizontal state, so the weighing sensor may shake accordingly.
That is, in this constant shaking, the cable is constantly wound to the weighing sensor, until it is pulled. Because of the influence of thermal expansion and cold contraction, the inclination of the two ends of the loader is large, which brings partial load. The larger the weighing value, the greater the bias load error. At the same time, this component is also related to the height of the weighing sensor, the relative influence of the weighing sensor with higher height is smaller, and the relative influence of the lower height is larger.
