In farm feed management, the accuracy of silo weighing systems is crucial. In order to ensure accurate measurement and efficient operation, selecting the right load cells for silos becomes a key task. Load cells for silos need to be properly selected to maximize their performance.
Generally speaking, if the feed bin has several support legs, several sensors should be used. Load cells for silos range selection can be based on the scale's maximum weighing value, the number of sensors, the scale's self-weight, the maximum possible bias load and dynamic load and other factors to determine a comprehensive evaluation. In general, the closer the range of the load cells is to the load assigned to each cell, the more accurate the weighing will be.
The accuracy rating of load cells for silos includes technical specifications such as nonlinearity, creep, creep recovery, hysteresis, repeatability, and sensitivity of the sensor. When selecting load cells for silos, do not simply pursue high grade sensors, but consider both meeting the accuracy requirements of electronic scales and their cost.
Farm silos often face harsh working environments, as frequent disinfection can cause equipment corrosion, outdoor seasonal and day night temperature differences, as well as dust effects, all require load cells to have high tolerance.
Corrosive environment: This environment will cause load cells for silos elastomers to be damaged or short-circuited, etc., so you should choose sensors that have been sprayed on the outer surface or have a stainless steel cover with good corrosion resistance and good sealing.
Temperature: High-temperature environments will cause the sensor to experience weakened adhesive, aging, weld cracking, and structural changes in the elastomer's internal stress. In this case, it is necessary to select a high-temperature-resistant sensor. In addition, there must be heat insulation, water cooling, or air cooling devices.
Dust, humidity: For some sensors working in humid, dusty environment, should choose the diaphragm heat sleeve sealing or diaphragm welding sealing, vacuum nitrogen-filled sensors.
Where and how load cells for silos are installed will directly affect their measurement accuracy and stability. When selecting load cells for silos, it is important to consider the structural characteristics of the silo, the feed flow characteristics, and the ease of maintenance. Ensure that they can be easily installed in the right place and that they are easy to maintain and calibrate. In addition, load cells for silos should have a long service life and low maintenance costs in order to minimize later operating costs.
When choosing the accuracy of load cells for silos, the accuracy of the sensor should be slightly higher than the theoretically calculated value. Because the theory is often limited by objective conditions. Such as the silo's working environment is relatively harsh and other factors have a direct impact on the accuracy requirements of the load cells. Therefore, to improve the requirements from all aspects, but also to consider the economic benefits, to ensure that the purpose.
