REPUTED Digital Tank Weighing System

Tank Weighing System:-

Tank weighing system normally consists of load cells, junction box and weighing controller. It is widely used in production management and process control areas where weight measurement & control is involved.

The general idea of tank weighing is to place load cells under each foot of the tank/hopper/vessel, then connects the load cells to a weighing controller through a junction box which is used to compensate the signal difference of the load cells. The weighing controller is able to display the weight value after the system is calibrated, the indicator is equipped with relays output, 0-5V/0-10V/4-20mA analog output and communication port for automation control purpose.

The most common concerns about choosing suitable load cells invole:

Mounting--Load cell needs to mounted under tank foot easily and firmly.

Accuracy--Different weighing applications have different requirements of measuring accuracy.

Capacity-- Uneven load distribution should be considered when choosing load cell capacity.

Ingress protection--Depending on the operating environment.

Before calibration, corner trimming is needed, which can be done through junction box, the point of corner trimming is to make sure every load cell gets the same output under same load, so the weighing system will get the same readout even though the weight is distributed unevenly.

Calibration is extremely important to get the weighing system work functionally.The difficult part is to find the dead weight for the span calibration��There are many ways to get the dead weight, water is most common used; weight measured by another proved weighing device is also a good choice
