Today, load cells have long penetrated into extreme areas such as industrial production, space development, ocean exploration, environmental protection, resource surveys, bioengineering, and even cultural relics protection, but load cells are basically used in the matching scale. In the heavy system, and the load cell in the supporting system, what do we need to pay attention to when choosing? How should we choose the load cell in different weighing systems?

When the load cell is actually used, the weight of the scale body and vibration, shock, and eccentric load should be considered. Therefore, the principle of using the weighing sensor range for different weighing systems is also different. In addition, the sensitivity of the load cell, the maximum number of divisions, and the minimum verification index value are also indicators that must be considered in sensor selection.

In the selection of the weighing sensor range, it can be determined according to the maximum weighing value of the weighing scale, the number of selected sensors, the weight of the scale body, the maximum eccentric load that can be generated and the dynamic load factor. First of all, the capacity of the selected load cell should be as close as possible to the value of the manufacturer's standard product series. Otherwise, the non-standard sensor is not only expensive but also difficult to replace after damage. Secondly, in the same weighing system, It is permissible to use a weighbridge sensor with a different rated load, otherwise the system will not work properly. In addition, the variable load refers to the actual load applied to the load cell. If there is a multiplying or multiplying mechanism between the weighing cells of the weighing platform, the influence should be considered. The actual working environment also has an impact on the use of symmetric weight sensors.
