Strain gauge load cell sensors are an essential and versatile technology that has a range of applications. From measuring force and weight to ensuring the safety of structures and machinery, strain gauge load cell sensors play a crucial role in various industries. In this article, we will explore how strain gauge load cell sensors work and their applications.
How do strain gauge load cell sensors work?
Strain gauge load cell sensors work on the principle of the resistance of a wire or foil changing when it is stretched or compressed. The strain gauge is attached to a solid object and as force is applied to the object, it deforms slightly, causing the resistance of the strain gauge to change. This change in resistance is then measured and converted into an electrical signal, which is proportional to the force applied to the object. This signal can be further processed and displayed as weight, force, or pressure.
There are different types of strain gauge load cell sensors, including bending, shear, and tension/compression load cells. Each type is designed to measure specific types of forces and is calibrated to provide accurate readings for its intended application.
