Single Point Sensor: Accurate Weighing of One Sensor
The single point load cell is one of the most widely used load cells in the world. Compared to other force sensors, these products allow force to be applied at different points without distorting the measurement results - this is ensured by the integrated parallelogram. As a result, only one load cell is required for high-precision weighing applications.
Single point load cells are suitable for a wide range of applications and are primarily used by factory engineers for manufacturing and industrial scale installations. Since only one load cell is used, users benefit from a simple design for weighing applications. But how exactly did the product become so popular? The history of single point load cells begins with the invention of strain gauges.
Strain gauges: the foundation of every load cell
As early as 1856, Lord Kelvin discovered that copper and iron wires increase in resistance when subjected to tensile stress. This laid the foundation for strain gage technology, which is the basis of today's single-point load cells. Edward E. Simmons and Arthur C. Ruge are considered the fathers of strain gauges. Interestingly, Ruge applied for a strain gauge patent in 1938 to the Massachusetts Institute of Technology where he worked. While MIT determined the development was "commercially unprofitable," Ruge was allowed to claim patents and revenue for himself. Today, strain gauges are considered an integral component of everything related to industrial weighing worldwide and are one of the most widely used technologies in industrial weighing worldwide.
