Belasningsceller

Belasningsceller, also known as load cells, are force transducers that convert a mechanical force into an electrical signal. This conversion is typically achieved through the use of strain gauges, which are bonded to a deformable element within the load cell. When a force is applied, the element deforms, causing the strain gauges to stretch or compress. This change in resistance of the strain gauges is then measured and processed by electronic circuitry to produce a precise output representing the applied force.

Load cells come in various designs, each optimized for different types of force measurement and applications. Common types include beam, S-type, button, and canister load cells. The choice of load cell depends on factors such as the magnitude of the force, the direction of application, environmental conditions, and the required accuracy. They are fundamental components in weighing systems, industrial automation, testing equipment, and many other fields where accurate force measurement is critical.

The electrical output from a load cell is usually a small voltage change, which is amplified and conditioned by a signal conditioner or transmitter. This processed signal can then be displayed on a digital readout, recorded by a data acquisition system, or used to control other processes. Calibration is a crucial step in ensuring the accuracy and reliability of load cells, involving the application of known forces and adjustment of the electrical output to match.
