Load cells, the devices used to measure force or weight, are precision-engineered components that require a meticulous manufacturing process to ensure their accuracy, durability, and reliability. Below is an overview of how load cells are produced:

Rotary torque transducer is an advanced device engineered to measure torque, or rotational force, applied to a rotating system such as a shaft, motor, or gearbox. It works by detecting torsional forces transmitted through a rotating element using strain gauges. These gauges measure deformation caused by torque and convert it into an electrical signal.

The underlying principle behind load cells lies in the use of strain gauges, which form the core sensing technology of these devices. Structurally, a load cell is built from a metal elastomer, typically aluminum, alloy steel, or stainless steel, to which foil strain gauges are meticulously bonded. When a load cell is subjected to stress—be it force, weight, or torque—the material of the elastomer undergoes deformation or displacement. This deformation results in strain, which the strain gauges detect and convert into measurable electrical signals.
