Selection Of Sensor Quantity And Range

The selection of the number of sensors is based on the purpose of the electronic scale and the number of points that the scale body needs to support (the number of support points should be determined according to the principle of making the geometric center of gravity of the scale body coincide with the actual center of gravity). Generally speaking, a few sensors are selected for a scale body with several support points, but for some special scales such as electronic hook scales, only one sensor can be used. For some electromechanical combined scales, the number of sensors should be determined based on the actual situation.
The selection of sensor range can be determined based on a comprehensive evaluation of factors such as the maximum weighing value of the scale, the number of sensors selected, the self weight of the scale body, the possible maximum bias load, and dynamic load. Generally speaking, the closer the range of a sensor is to the load assigned to each sensor, the higher the accuracy of its weighing. However, in practical use, due to the load added to the sensor, in addition to the weighed object, there are also loads such as the weight of the scale body, tare weight, eccentric load, and vibration impact. Therefore, when selecting the sensor range, many factors should be considered to ensure the safety and lifespan of the sensor.
