The weighing and control system can be applied to: reaction kettles, reaction pots, hoppers, tanks, storage tanks, stirred tanks, tanks, vertical tanks, etc. The weighing and control system is composed of: multiple weighing modules, multiple junction boxes (with amplifiers), display instruments. Weighing and control system components: multiple weighing modules, multi-way junction box (including amplifier), display instrument.

Selection of the number of weighing modules: for tanks with support feet installed, the number of weighing modules is determined according to the number of support feet, in general, several load cells are used for several support feet. If it is a newly installed container, if it is a vertically placed cylindrical container, it is more stable to use three-point support. If you consider the wind, shaking, vibration and other effects, four-point support is appropriate. Horizontally placed containers with four-point support is appropriate.

Weighing module range selection: fixed load (platform, dosage tanks, etc.) + variable load (load to be weighed) ≤ load cell rated load × the number of sensors × 70%, of which 70% of the coefficient is to take into account the factors of vibration, shock, partial load and added.

Weighing and control system working principle: the tank weighing system is to collect the weight of the tank by using the weighing module on the legs of the tank, and then transmit the data of multiple weighing modules to the instrument through the multi-input and single-output junction box. The instrumentation allows the weight of the weighing system to be displayed in real time. A switching module can be added to the instrument to control the feeding motor of the tank through a relay switch. Alternatively, the instrument can give RS485, RS232 or analog signals to transmit the weight information of the tanks to a PLC or other control device, which can then carry out more complex control.
