How a Load Cell Works

Load cells are used in everyday life, but some people have no idea what they are. The Youtube video “What is a Load Cell?” explains everything perfectly with real-life examples that any average person can easily understand. Let’s find out more!

If you’ve used a weight scale at home, you’re actually near a load cell, which is just a force gauge. It consists of a transducer, which is used to create an electrical signal with a magnitude proportional to the force that’s being applied to it.

There are four kinds of common load cells: pneumatic, hydraulic, strain gauge, and capacitance.

As the name suggests, a pneumatic load cell deals with air pressure, and this kind contains an elastic diaphragm adhered to a platform surface where the weight will go so it can be measured. There’s also an air regulator, which controls the amount of air pressure that goes into the meter, and a pressure gauge as well. When a weight is placed on a pneumatic load cell, the pressurized air or gas will balance the bulk of the object to determine its exact value.
