belasningscell
A belasningscell, often translated as a load cell, is a transducer that converts a force into a measurable electrical signal. It is essentially a type of force sensor. The fundamental principle behind a belasningscell is the use of a strain gauge, a device whose electrical resistance changes when it is stretched or compressed. These strain gauges are typically bonded to a precisely engineered metal structure, known as a flexure. When an external force is applied to the flexure, it deforms slightly, causing the strain gauges to stretch or compress. This deformation results in a change in the electrical resistance of the strain gauges. This change in resistance is then measured and amplified, often by a Wheatstone bridge circuit, to produce an electrical output that is proportional to the applied force. Belasningsceller are widely used in various applications where accurate force measurement is required. This includes weighing scales, industrial process control, material testing machines, and even in aircraft to measure wing stress. Different types of belasningsceller exist, designed to measure specific types of force, such as tension, compression, shear, or bending. Their accuracy and sensitivity depend on their design, materials, and manufacturing precision.
