load cell is an electronic component (or transducer) to which a weight/force is applied.

It converts the weight/force applied to the load cell into an electrical signal (in units of millivolt or mV) that is proportional to the mechanical deformation (stresses and strains) caused by that weight/force.

A high quality load cell is able to deform under that weight/force in an extremely repeatable manner, just like a good mechanical spring.

Typical applications:

  • Scales
  • Packaging machinery
  • Dosing and filling machinery
  • Level/Inventory Control on Tanks and Silos
  • Test Machinery
  • Quality Control

Typical materials used to manufacture load cells are special alloys with high strength, high fatigue life, high repeatability, high linearity and low hysteresis. For example steel alloys, stainless steels, aluminium alloys, beryllium-copper and others.
