What is a Load Cell?
The load cell is the most important component of a digital scale system and is located inside every digital scale. All digital scales rely on these transducers; without them, a scale can’t measure weight. Load cells contain a strain gauge, which measures electrical currents and resistance when weight is applied.
When weight is applied to the scale, the load cell will slightly bend to measure applied force and send an electrical output to the indicator. This then calculates weight based on the severity of the load cell’s bend and displays a digital number, representing weight, on its screen. The more weight that is applied to the load cell, the more the load cell bends, resulting in a greater change in resistance and, therefore, a greater weight value.
What are the Types of Load Cells?
There are different types of load cells for different applications, including S-beam, single-ended beam, double-ended beam, single point, rocker column, compression canister, tension and planar beam. Choosing the right load cell can be complicated, and experienced load cell experts can help.
Rice Lake Weighing Systems has several different load cell types to help measure the weight in anything from a bench scale to a truck scale. Learn more about load cells at Rice Lake’s Load Cell and Weigh Module Resource Center and consult with Rice Lake load cell experts whenever you need help choosing the correct load cell for your business.
