Fiber optic displacement sensor FOD

1、 Introduction to Fiber Optic Displacement Sensor FOD:

FOD fiber optic linear positioning and linear displacement sensors are used to monitor the relative motion of adjacent surfaces at cracks or joints in concrete and rock. Using the Fabry Perot white light interferometry principle, FOD is designed for harsh environments, so it is packaged with sturdy composite materials or aluminum.


1、 Performance characteristics of fiber optic displacement sensor FOD:
Accurate, reliable, high-resolution, inherently safe, and free from electromagnetic, radio frequency, and lightning interference. Can operate at temperatures up to 170 ℃.
1) Range: 20mm
2) Accuracy: ± 0.002 mm
3) Resolution: 0.002 mm

2、 Fiber optic displacement sensor FOD application:
Fiber optic displacement sensors (FODs) are widely used in geological exploration, industrial monitoring, and other fields due to their characteristics of being free from temperature and electronic interference, and possessing ultra precision.
