Monitoring torque and rotational stress is essential in mechanical systems from wind turbines to aerospace actuators.
Proximion’s FBG fiber-optic rotational load sensors measure torque by detecting torsional strain in optical fibers.

Sensing Principle
A FBG optical fiber sensor bonded to a shaft or torsion element will experience a twist when torque is applied. The induced torsional strain produces a change in fiber birefringence and hence FBG period. A precision interrogation unit translates this into torque measurement.
