Load Cell
A load cell is a force transducer that converts an applied mechanical load into a measurable electrical signal, typically using strain gauges bonded to a deforming element. Load cells are the core sensing element in industrial weighing, force measurement, and tension or compression monitoring.
When force is applied, the load cell's structural element deforms slightly, changing the resistance of attached strain gauges arranged in a bridge circuit, which produces a proportional output voltage. Designs include bending beam, shear beam, and compression types for different ranges and mounting needs. Load cells matter because accurate weight and force measurement is essential for batching ingredients, filling, checkweighing, tank inventory, and process control, where small measurement errors can affect quality and cost.
