How do Load Cells Work

Load cells are part of our product portfolio at Variohm. They are used for weighing applications in a variety of environments.

Different types of load cells use different technologies. Most of the load cells we offer use strain gauge technology. Strain gauges are very small devices which react to force or load.

Strain gauge load cells convert the force applied to them into electrical signals. The strain gauges are bonded to the load cell in a precise location so that they will deform when force is applied. This type of load cell is becoming increasingly popular and more accurate compared to other types.

Most strain gauge load cells use four strain gauges which ensure maximum sensitivity; two in tension, and two in compression, they are then wired with compensation adjustments to take accurate measurements.

When force is applied to the load cell, the strain gauges are compressed which changes the electrical resistance within them in proportion to the force.

Other types of load cell technology include;

Hydraulic load cells
Pneumatic load cells
Piezoresistive load cells
Inductive load cells

What are load cells used for?

The main use for load cells is for weighing applications. These types of applications are found in almost all industries which is why there are loadcells which are suitable for subsea environments, aerospace environments, industrial applications etc. Load cells come in many shapes and sizes – some as small as a 1 Euro cent, this is so that they can be fitted into different applications.

Applications include;

Belt scales
Hopper scales
Platform scales
Onboard weighing
Tipper truck
Forklifts
Tank scales
Electrical transmission cables
Food scales
Hazardous environment scales
