The electronic weighing machine uses a load cell to measure the weight produced by the load here most load cells are following the method of a strain gauge.
Load cell used in weighing machine.
In short load cell can be used wherever there is a requirement of force measurement.
This is a simple arduino weight measurement project.
Such load cells are typically available in many rated loads i e maximum loads.
Commonly used ones include.
Load cells are used in several types of measuring instruments such as laboratory balances industrial scales platform scales and universal testing machines.
In today s processing plants electronic force sensors are preferred in most applications although mechanical lever scales are still used if the operation is manual and the operating and maintenance personnel prefer their simplicity.
This is enough for this project.
Types of load cells.
The load cells with lower accuracy but reasonably accurate are classified as d1 c1 and c2.
A weighing system with load cells built in or a system with pressure transducers built in are incorporated into various machine tools or industrial robots which are used in steelmaking cement foods pharmaceutical chemical for the purpose of measurement monitoring or control on various tests recent trends toward labor saving quality.
Single point load cells.
It is used in weigh axle weighing scales tank scales weighbridges vessel weighing applications etc.
Several load cells are positioned under a steel structure and are loaded with a weight from above.
There are different types of load cells for different applications.
This particular load cell is commonly referred to as a straight bar load cell or a parallel beam load cell.
Bending beam load cells.

Canister type this type of load cell is usually used for single as well as multi weighing applications.
They are available in different sizes shapes and capacities.
There are different types of load cells available.
The one utilized in this project is rated for a maximum weight of 10kg or 22 pounds.
C3 grade load cell are used in quality assurance such as checking weight of ball bearings machine constructions parts etc.
From 1993 the british antarctic survey installed load cells in glass fibre nests to weigh albatross chicks.
A load cell is located under a platform that is loaded with a weight from above.
Its advertised rated output is.
And it s therefore useful in hotels.
Weighing load cell applications load cells represented the first major design change in weighing technology.
Types of load cells.
This particular weighing machine can be used for weighing of all types of small sized granular products like prepared herbal medicine tea seeds msg seasoning coffee beans chocolate beans etc.
They are used load testing machines industrial scales flow meters etc though we hardly ever come in direct contact with the load cells.
