Force / load cell installation and use precautions - Solutions - Huaqiang Electronic Network

Proper installation and usage of load cells or force sensors are crucial for ensuring their accuracy and longevity. Even though these devices are designed to be reliable, improper handling or setup can lead to errors or damage. Here are some key considerations to keep in mind when working with force or weighing sensors:

1. Handle the sensor with care, especially smaller models made from aluminum alloy. Any impact or drop can cause significant output errors.

2. Ensure that the loading device is properly aligned so that the applied force acts directly along the sensor's axis. This helps reduce errors caused by misalignment or eccentric loads.

3. Level the mounting surface using a spirit level if you're using a single sensor. If multiple sensors are used, make sure the base remains as flat as possible to maintain consistent performance across all units.

4. Always select a sensor with a rated load that matches the expected range of your application. While some sensors have overload capabilities, it's best to avoid exceeding their limits during use.

5. Keep the mounting surface clean and smooth, free from oil, grease, or any contaminants. The base itself should be strong and rigid enough to support the sensor effectively.

6. Do not attempt to open the sensor housing, protective cover, or cable connectors, as they are sealed for protection against environmental factors.

7. Protect the sensor from chemical exposure. Apply a thin layer of vaseline on its outer surface if needed, and avoid exposing it to direct sunlight or extreme temperature changes.

8. If necessary, install protective shields or shock-absorbing devices to prevent accidental damage.

9. Avoid welding near the sensor after installation, as high currents can damage the internal components.

10. Install a copper braided wire bypass at both ends of the loading device to protect the sensor from electrical interference.

11. Never extend the sensor cable yourself. If an extension is required, solder the connection and apply waterproof sealant to prevent moisture ingress.

12. Use baffles or covers around the sensor to prevent debris from entering moving parts and affecting measurement accuracy.

13. Keep the sensor cable away from high-voltage lines or areas with electromagnetic interference. If unavoidable, route the cable through a metal conduit and minimize the length of the connection.

14. Even if the sensor has some overload capacity, it’s important to avoid overloading it during operation. Short-term overloads can also cause permanent damage.

15. For high-precision applications, allow the sensor and measuring instrument to warm up for at least 30 minutes before use.

16. Store and operate the sensor in a dry, well-ventilated area, away from corrosive substances.

Following these guidelines ensures optimal performance and extends the lifespan of your force or load cell. Some users may experience fewer issues because they follow these best practices carefully. Understanding and applying these tips can make a big difference in the reliability and accuracy of your measurements.
