Information to be confirmed for selecting the German HBM weighing sensor

1. Determine the required number of German HBM load cells

Whether it is HBM from Germany or other brands of weighing sensors, it is necessary to determine the required number of weighing sensors. A scale may use one or more weighing sensors, and the required number of weighing sensors should be determined based on the purpose of the scale and the number of supporting points of the scale body. The required number of sensors should be equal to the number of supporting points, such as belt scales that require multiple sensors, And only one sensor is needed for hook scales and others.

2. Determine the model of the weighing sensor

　　German HBM weighing sensorThere are many models available, and to choose a suitable model, it is necessary to consider the weighing type, installation space, and manufacturer's suggestions comprehensively. In order to ensure the appropriate installation and safe and reliable weighing of the sensor, the sensor manufacturer will make regulations on the applicable range of the sensor based on the characteristics of the force, performance indicators, installation form, structural type, and elastic material. For example, small household scales such as pricing scales and desk scales should use cantilever beam sensors; Large industrial scales such as hopper scales and electronic belt scales should use steel cantilever beam sensors; For example, some scales such as track scales and car scales that carry large tonnage should use steel bridge sensors.

3. Determine the required range for the weighing sensor

There are significant differences in the range and accuracy of different models of HBM weighing sensors. The selection of weighing sensor range should be based on factors such as the number of weighing sensors, the expected maximum bearing capacity of the weighing device, the weight of the weighing device itself, the estimated maximum bias load, and dynamic load. The selected range of the weighing sensor should be close to the actual weight of the weighing device, which can make the measurement value of the sensor more accurate.

It should be noted that during the weighing process, in addition to withstanding the pressure transmitted by the item, the sensor will also be subjected to a certain amount of impact force. When determining the range, this part of the impact force should be taken into account to prevent damage to the sensor in the future due to instantaneous overload.
