Will the sensor be damaged at the moment of an explosion or high-velocity impact?
Fiber Bragg Grating (FBG) sensors, especially bare fiber or standard polymer-encapsulated types, are susceptible to damage from direct explosions or extreme high-velocity impacts. The survivability of the sensor depends heavily on the intensity of the impact and the sensor’s packaging.
While FBG sensors offer intrinsic safety in flammable and explosive environments because they do not carry electricity and thus pose no ignition risk, this characteristic is distinct from their mechanical resistance to the forces generated by an explosion or impact.
For applications requiring enhanced mechanical robustness, we recommend the OFSCN® Alloy Tube Packaged Fiber Bragg Grating strain sensor. This sensor features seamless metal tube encapsulation, which provides significantly greater protection against external forces compared to other encapsulation methods. However, it is important to note that even with robust packaging, direct exposure to an explosion or an impact that exceeds the material’s yield strength or the optical fiber’s breaking strain will likely result in damage or destruction of the sensor.
