A weighing cell for an electronic scale

Electronic scales play a very important role in our life. It can be said that without electronic scales, our daily transactions would not be possible. It can be seen that the status of electronic scale is how important. Due to the advantages of direct reading, quick weighing and convenient operation, electronic scale has gradually replaced the previous steelyard and mechanical scale. Electronic scale is generally composed of weighing sensor, weighing instrument and force transmission structure, and the best reputation of weighing sensor is resistance strain sensor, this sensor deformation under the action of external force, resulting in the output signal change, display reading on the weighing instrument. However, this kind of sensor in the use of the following problems, you can refer to, if your own electronic scale has these problems, you can conclude that the weighing sensor is out of order.
First: whether there is an item on the electronic scale or not, the data displayed on the electronic scale will fluctuate or drift. If you have this problem, the sensor is broken and you need to replace it with a new sensor.
Second: electronic scale in weighing the same item, each display data are different, and the gap is relatively large. If this happens to you, the sensor is broken.
Third: electronic scale display instrument display data is zero, but when adding the object, the weight of the object is not shown. If this happens to you, you can assume that the sensor is broken.
Fourth: when the electronic scale starts up, the data of the display instrument is not shown as zero, and the display screen has been jumping. If this happens to you, you can assume that the sensor is broken.
