To explain how a Digital Electronic Scales works, it would be necessary to first discuss its main components. These include the structure, a load cell, and signal conditioner.

Structure: this is the physical outlook of the weighing machine and is majorly the surface that bears the load. As you could imagine, the physical structure houses the electronic circuit behind the function of the scale as well as the load cell. The structure of a digital scale comes in different designs depending on the brand. Also, it may be necessary to have the structure sit on the load cells especially where high loads are involved. An example is the digital scales used on weighbridge and industries.

Weight indicator: many digital scales come with an LCD screen where the measurements of the weight obtained are displayed.

The Load Cell: this is a transducer whose significant function in the scale is to convert the force exerted by the object of measurement into an electrical signal. Some digital weigh scales have more than one load cells. Small or low capacity scales have only one load cell. Floor or dormant digital weighing machines comprise of four cells. Those with high rating capacity such as truck scales may have between 4 to 8 load cells.

Notably, the load cells determine the recommended capacity of the weigh scale. Even if the mechanical structure is strong enough to withstand higher loads, one is required to consider the rated capacity if they are to get precise results.

Signal Conditioner: this is the electronic component of the digital scale. Various functions of this component include powering the load cell, receiving electrical signal by the load cell and converting it into intelligible numbers, electronically referred to as the digital output. Today’s scales are programmed to display the digital output in different units of measurements to fit the needs of users.
