Fiber Optic Sensing Solutions

What is a Fiber Optic System? Considerations for Choosing Fiber Optic Technology Fiber Optic systems are comprised of a fiber amplifier and optical fibers. The amplifier, or sensor, emits, receives, and converts the light energy into an electrical signal. Individual fiber optic assemblies simply guide light from the amplifier to a sensing location, or from the sensing location back to the amplifier. Think of an optical fiber as being similar to a garden hose: like a hose transports water, the fiber transports light from one end to the other. The main advantage of fiber optic sensors is the versatility....

Why Fiber Optics? Compact Size for Tight Sensing Locations • The small size and flexibility allow positioning and mounting in tight spaces • Plastic fiber optic assemblies are usually single strands of optical fiber and can be routed into extremely tight areas • Plastic fibers also survive well under repeated flexing • Pre-coiled plastic fiber optics are available for sensing applications on reciprocating mechanisms Reliable Performance in Harsh or Explosive Environments • Fibers can be constructed to survive in areas with corrosive material or extreme moisture and are immune to electrical noise...
