4 points to pay attention to when replacing load cells

 During the use of electronic scales (including electromechanical scales), plastic deformation of the sensor will be caused due to overload, impact and other reasons, which will affect the accuracy of measurement. In severe cases, the sensor will be damaged and cannot be used normally and must be replaced. According to the author’s experience, the following issues should be noted during the replacement process:

1. As the rated load increases, the output microvolt/division signal of the load cell decreases instead of increasing with the increase of the rated load.

2. For the electromechanical combined scale that installs the S-shaped sensor in the second force transmission link (ie the link between the first force transmission lever and the second force transmission lever), please note: the length of the linkage after the sensor is reinstalled Same length as the original link.

3. The commissioning of the electromechanical integrated scale after replacing the sensor should be carried out according to the manual of the weighing display instrument on the basis of accurate commissioning of the mechanical scale.

4. Whether it is an electronic scale or an electromechanical combined scale, after the sensor is replaced, it must be verified before it can be used.
