The selection of the weighing module generally selects the range of 3 sets or 4 sets of modules according to the support point of the container. Due to the self-weight of the scale body (container), vibration shock, partial load and the like, generally the following The rules are chosen.
Selection of the range of the static load weighing module The static load weighing module system is generally composed of a measuring device (carrier), a static load weighing module (load cell) and a weighing display controller. The load cell is mainly used for mass and force measurement. For the accuracy and reliability of weighing measurement, when designing the weighing and measuring device, for the system composed of multiple weighing sensor modules, the weighing sensor module range is generally selected. Follow the principles below.
Multi-sensor static weighing system:
Fixed load (weighing platform, container, etc.) + variable load (load to be weighed) ≤ selected sensor rated load × number of sensors × 70%, 70% of which is considered in consideration of vibration, shock and partial load factors of.
Specifically, when the coefficient is too small, the effective range of the sensor is small, the resolution of the instrument is required to be high, and the stability of the instrument is relatively low, but the service life of the sensor is high. When the coefficient is too large, the effective range of the sensor is large, the resolution of the instrument is required to be low, and the stability of the instrument is relatively high, but the service life of the sensor is low. Therefore, when selecting the range of the load cell, it is necessary to consider the relevant factors.
Other precautions for static load weighing module selection When selecting the static load weighing module, the material of the static load weighing module (carbon steel anti-corrosion treatment or stainless steel material) should be determined according to the site conditions (preservation and explosion-proof requirements). ), protection and explosion-proof grade requirements.
