Explore the mechanics, features, and diverse applications of pancake load cells in various industries, from aerospace to biomedical.
Pancake Load Cells: Understanding the Mechanics and Applications
Pancake load cells, also known as low-profile or universal load cells, are a unique type of force sensor designed for a variety of testing and measuring applications. They derive their name from their distinct flat, round shape reminiscent of a pancake. Unlike other load cells, they are specifically engineered to measure both tension and compression forces. This versatility, along with their robust design, makes pancake load cells highly sought after in numerous industries.
Working Principle
At the heart of every pancake load cell is the concept of strain gauges. Strain gauges are electrical conductors firmly attached to a film. When a force is applied to the film, the conductor’s length changes, resulting in a change in electrical resistance. This resistance change is proportional to the force applied, which is how the load cell measures force.
Pancake load cells utilize several strain gauges in a Wheatstone bridge configuration. This specific setup enhances the accuracy of force measurements by compensating for temperature changes, which may otherwise affect the strain gauges’ performance.
