Fiber Optic Sensor Clamping Device for Temperature Compensation

The patent introduces an intermediate carrier as a mediator between the optical fiber sensor and the measurement object. This intermediate carrier serves as a buffer that isolates the sensor from direct thermal and mechanical influences of the harsh environment, while still transmitting the mechanical structural changes to be measured. The intermediate carrier protects the optical fiber from temperature variations and external harmful factors, allowing accurate measurement of mechanical changes without interference from environmental conditions.

The patent employs lever-free mechanical signal amplification that operates in a different dimensional space. Instead of using traditional lever mechanisms that add mechanical complexity, the system uses the intermediate carrier to create a geometric amplification effect through spatial arrangement and distance ratios. This dimensional approach allows the sensor to detect minute mechanical structural changes with high resolution while maintaining direct attachment to the measurement object, effectively converting small displacements into measurable optical signal changes.

The patent achieves temperature compensation by changing the physical parameters of the intermediate carrier, specifically its coefficient of thermal expansion. By selecting materials and designing the intermediate carrier with appropriate thermal expansion characteristics, the system passively compensates for temperature variations. The intermediate carrier's thermal expansion properties are matched to counteract the effects of temperature changes on the optical fiber sensor, providing automatic temperature compensation without adding complex active control systems or multiple sensor elements.
