Precautions for installing load cells

Weighing sensors should be handled with care, especially for small-capacity sensors that use alloy aluminum materials as elastomers. Any impact or drop caused by vibration is likely to cause a large output error. When designing the loading device and installing it, ensure that the loading axes of the load cells coincide with each other to minimize the effects of tilt loads and eccentric loads.

In terms of level adjustment. If a load cell is used, the installation surface of its base should be adjusted with a level until it is horizontal. If multiple sensors are measuring at the same time, the installation surface of their bases should be kept on a horizontal plane as much as possible. The main purpose of this is to In order to ensure that the force endured by each sensor is basically the same.

Determine the rated load of the load cell used according to the range selection of the load cell in its instructions. To prevent chemical corrosion, it is advisable to coat the outer surface of the load cell with Vaseline during installation. Direct sunlight and use in locations with drastic changes in ambient temperature should be avoided. Add a bypass made of copper braided wire to both ends of the load cell loading device.

Cables should not be lengthened by themselves. When lengthening is really needed, the joints should be soldered and moisture-proof sealant should be added. It is best to use some baffles around the load cell to cover the sensor. The purpose of this is to prevent debris from falling into the moving parts of the sensor and affecting its measurement accuracy.

The cable of the sensor should be kept away from strong power lines or places with pulse waves. When avoidance is unavoidable, the cable of the load cell should be inserted into the iron pipe alone and the connection distance should be shortened as much as possible.

Determine the rated load of the sensor used according to the load cell range selection in its instructions. Although the load cell itself has a certain overload capability, this situation should be avoided during installation and use. Sometimes a short-term overload may cause permanent damage to the sensor.

In high-precision applications, the load cell and instrument should be warmed up for 30 minutes before use.
