Load cells are fundamental components in modern weighing and force measurement systems. Class B load cells, in particular, represent a specific accuracy classification that serves various industrial applications. This comprehensive guide will explore every aspect of Class B load cells, from their basic principles to advanced applications.
A Class B load cell is a precision force measurement device that falls within a specific accuracy classification according to international standards. These devices convert mechanical force into measurable electrical signals, providing reliable weight measurements for industrial applications. Class B designation indicates a moderate level of accuracy suitable for many commercial and industrial weighing applications.
Class B load cells operate on the principle of strain gauge technology. When force is applied, the metal body of the load cell deforms slightly, causing the internal strain gauges to change their electrical resistance. This change is converted into an electrical signal proportional to the applied force, allowing for precise weight measurement.
Class B load cells find extensive applications across various industries:
