What problems should be paid attention to in weighing module selection

The selection of weighing module is generally based on the supporting point of the container to select the range of 3 or 4 modules. Due to the weight of the scale body (container), vibration and impact, partial load, etc., generally follow the following Rule selection.

Static load weighing module range selection The static load weighing module system is generally composed of three parts: a measuring device (carrier), a static load weighing module (load cell) and a weighing display controller. The load cell is mainly used for the measurement of mass and force. For the accuracy and reliability of weighing measurement, when designing a weighing measurement device, for a system composed of multiple load cell modules, the range of the load cell module is generally selected Follow the following principles.

Multi-sensor static weighing system:

Fixed load (weighing platform, container, etc.) + variable load (load to be weighed) ≤ the rated load of the selected sensor × the number of sensors × 70%, of which 70% of the coefficient is added considering vibration, shock, and partial load of.

Specifically, if the coefficient is too small, the effective range of the sensor used is small, and the resolution of the instrument is required to be high, and the stability of the indicator value is relatively low, but the service life of the sensor is high. When the coefficient is too large, the effective range of the sensor used is larger, and the resolution of the instrument is required to be low, and the stability of the indicator value is relatively high, but the service life of the sensor is relatively low. Therefore, when selecting the range of the load cell, relevant factors must be considered comprehensively.

Other precautions for the selection of static load weighing module When selecting the static load weighing module, it is also necessary to determine the material of the static load weighing module (carbon steel anti-corrosion treatment or stainless steel according to the site conditions (anti-corrosion and explosion-proof requirements)) ), protection and explosion-proof grade requirements, etc.
