Selection and use of oil level sensor

The choice of the number of oil level sensors is based on the purpose of the electronic weighing instrument and the number of points that the scale body needs to support (the number of support points should be determined according to the principle that the geometric center of gravity of the scale body coincides with the actual center of gravity). Generally speaking, if the scale has several supporting points, several sensors are used. However, for some special scales such as electronic hook scales, only one sensor can be used. For some electromechanical scales, the selection of sensors should be determined according to the actual situation. Number.

The selection of the oil level sensor range can be determined based on the comprehensive evaluation of the maximum weighing value of the scale, the number of selected sensors, the weight of the scale body, the maximum possible partial load and the dynamic load. Generally speaking, the closer the range of the sensor is to the load assigned to each sensor, the higher the accuracy of its weighing. However, in actual use, because the load on the sensor is not only the object being weighed, but also the weight of the scale body, tare weight, eccentric load, vibration and shock, etc., when selecting the sensor range, many factors must be considered to ensure The safety and life of the sensor.
