Can pressure, displacement, and vibration be measured simultaneously?
Yes, it is technically possible to measure pressure, displacement, and vibration simultaneously using Fiber Bragg Grating (FBG) technology. This can be achieved by deploying a network of different FBG sensors, each designed or configured to be sensitive to a specific physical parameter, potentially on the same optical fiber.
For displacement measurement, you would typically use an OFSCN® Fiber Bragg Grating Displacement Sensor. This sensor extracts displacement from strain measurements, and its structure is similar to our strain sensors.
For pressure measurement, specifically multi-directional force, the OFSCN® Fiber Bragg Grating 3D Force Sensor is designed for multi-directional pressure sensing on solid surfaces. It incorporates multiple FBG measurement sections to detect forces in different directions.
For vibration measurement, FBG sensors are well-suited due to their high-frequency response capabilities. Vibration can be detected as dynamic strain or displacement using appropriately designed FBG strain or displacement sensors.
All these FBG sensors benefit from inherent advantages like immunity to electromagnetic interference (EMI) and the ability for multi-point sensing within a single fiber network, which is crucial for simultaneous, multi-field coupled measurements.
