In order to ensure the accuracy of the load cell/load cell, there are still some problems in the process of installation and use. Please pay attention to the following details when installing and using the force/weighing sensor to ensure the accuracy and use of the force measurement/sensor measurement. life:
1. The force/weighing sensor should be handled lightly, especially for small-capacity sensors that use alloy aluminum as the elastomer. Any shock or drop caused by vibration is likely to cause a large output error.
2. Design the loading device and the installation should ensure that the action line of the loading force coincides with the force axis of the force measuring/weighing sensor, so that the effects of the tilting load and the eccentric load are minimized.
3. In terms of level adjustment. If a single force/load cell is used, the mounting plane of the base should be adjusted to the level using a level; if multiple sensors are simultaneously measured, the mounting surface of the base should be kept at a level as much as possible. The purpose of this is mainly to ensure that the power of each sensor is basically the same.
4. Determine the rated load of the sensor used according to the range selection of the force/load cell in its description.
5, the base mounting surface of the sensor should be as smooth and clean as possible, without any oil or film. The mounting base itself should have sufficient strength and rigidity and typically require strength and stiffness above the sensor itself.
6. The sensor case, protective cover and lead connector are sealed and the user is not allowed to open.
7, to prevent chemical corrosion. The Vaseline should be used to smear the outer surface of the load cell/load cell. Avoid using direct sunlight and drastic changes in ambient temperature
8. If it is unavoidable, install protective or mitigation devices.
9. In order to prevent the large current from directly licking the sensor body and damage the sensor, it is forbidden to carry out the welding work after the sensor is installed.
10. Add a bypass device made of copper braided wire at both ends of the load cell/weighing sensor loading device.
11. The cable should not be lengthened by itself. When it is really necessary to lengthen, it should be soldered at the joint and add moisture-proof sealant.
12. It is best to use some baffles around the force/load cell to cover the sensor. The purpose of this is to prevent debris from falling into the moving part of the sensor and affecting its measurement accuracy.
13. The cable of the sensor should be away from the strong power supply line or the place with pulse wave. When the competition cannot be avoided, the cable of the load/load cell should be inserted into the iron pipe separately, and the connection distance should be shortened as much as possible.
14. According to the measurement/weighing sensor range selection in the description to determine the rated load of the sensor used, although the force/load cell itself has a certain overload capacity, it should be avoided during installation and use. Happening. Sometimes overloading for a short period of time may also cause permanent damage to the sensor.
15. In the case of high precision use, the force/load cell and instrument should be used after 30 minutes of warm-up.
16. The sensor should be placed in a dry, ventilated, non-corrosive atmosphere.
Installation and use of the force / load cell should pay attention to these details, why some users use the sensor is not easy to break, but some users have not had problems, this is the same with the force / load cell It is related to the precautions for installation and use. After reading the above introduction, you may know something about it.
