What problems should be paid attention to during the installation of the load cell

1. InstallationLoad cellThe mounting surface of the base shall be leveled and cleaned without all oil slicks, gummed paper and other dirt. The mounting base itself should have sufficient compressive strength and rigidity, and the general rule is higher than the compressive strength and tortuous rigidity of the sensor itself.

2. The weighing sensor should be handled with care, especially the small measuring range sensor with polyurethane elastomer raw material made of aluminum alloy profile. All impact and falling are likely to cause hazards that cannot be retained due to its metrological verification characteristics. For the large space of the load cell, in general, it has a lot of its own weight, so the rules in the transport, installation, try to use the appropriate lifting machinery and equipment.

3. The loading orientation of each weighing sensor is full of clear, and when the sensor is used, the load must be loaded on the orientation here. The transverse force, rated bending distance and torque force shall be reduced as much as possible.

4. Level adjustment: Level adjustment has two levels of content. One is that the installation plan of a single sensor installation base should be adjusted with a level gauge. On the other hand, it means that the installation surfaces of the installation bases of several sensors can be adjusted to a level appearance as much as possible. Especially in weighing equipment with more than three sensors, more attention should be given to this point. The key purpose of doing so is to better make the load on each sensor basically consistent. Let the measurement and verification of electronic weighing instruments be more accurate and the use of sensors be more comprehensive.

5. The surrounding of the weighing sensor should be set as far as possible some "partitions", and even use thin metal sheets to cover the sensor. That can prevent dirt from contaminating the sensor and some moving parts, and this kind of "contamination" usually makes the moving part of the fitness exercise sad and endangers the weighing precision mi.

6. As far as possible, choose the structure parts with automatic and accurate positioning effect, such as ball rolling bearing, roller bearing, accurate positioning and tightening device, etc. They can prevent some cross-force effects on the sensor. It should be noted that some transverse force is not formed by the installation of mechanical equipment, such as the transverse force formed by thermal deformation, the transverse force formed by wind speed, and the transverse force formed by the sensation of mixing and installation on some container-type electronic weighing instruments, that is, the transverse force is not formed by the installation of mechanical equipment.

7. Some electronic weighing instruments have accessories that must be received on the scale body. We should make them as soft as possible in the position where the sensor is loaded into the spindle bearing to prevent them from "swallowing" the real load of the sensor and forming deviation.

8. Although the weighing sensor has a certain load working capacity, it should be thrown to prevent the sensor from being overweight during the whole process of weighing equipment installation. Be careful that even short-term overweight is likely to lead to sensor destruction. In the whole process of installation, if it is really necessary, the sensor can be replaced by a maintenance layer cushion block with the same aspect ratio as the sensor, and then the sensor can be replaced after all. In all normal work, the sensor should generally set the mechanical equipment parts for overpressure maintenance.

9. Whether the system software has any sad situation of fitness exercise can be distinguished in the following ways. That is, raise or lower the rated load by about 1‰ on the weighing platform to see if the weighing display is showing any performance, indicating that the moving part is not "contaminated".

10. If the extruder screw is used to fix the sensor, the rules have a certain tightening torque, and the extruder screw should have a certain tightening external thread deep. Generally speaking, the fixed extruder screw should use high toughness extruder screw.

11. When the sensor is installed, it is forbidden to use the arc welding method. When the weighing system requires arc welding, zui should take out the sensor and separate the machine equipment. If the sensor cannot be separated from the machine equipment, it is necessary to ensure that the machine equipment is well grounded before arc welding. If there is a large amount of current, the internal power supply circuit or electronic components will be damaged according to the sensor.
