Overview
The RKS compression tension sensors are designed for precise measurement of large axial forces. The sensors utilize an external ring attached to the assembly surface with screws, and the force is introduced via the contact surface. They are equipped with full bridge strain gauges, enhancing accuracy by distributing single strain gauges along the circumference.
