Glass Fiber Optics

Glass Fiber Optics Specifications

Construction

Combination of optical glass fiber, stainless steel or PVC, brass, molded thermoplastics, and optical-grade epoxy.

Optical fiber is F2 core, EN1 clad, approx. 50 µm diameter per strand. Flexible steel interlock sheathing is 302

stainless.

Sensing Range

Refer to the specific fiber optic to be used.

Bend Radius

Inside bend radius must b 12 mm or greater for PVC covered fiber optic assemblies, and 25 mm or greater for

stainless steel armored cable covered fibers.

Length

Standard length for assemblies is 915 mm; see dimension diagrams.

Most models are available from the factory with shorter or longer cable lengths, up to 18 m max.

Length Dimension Tolerance

Overall assembly length: ±12 mm per 300 mm of length

Shrink junction dimensions: ±12 mm

Implied Dimensional

Tolerances

All dimensions are in millimeters: x = ±2.5 mm, x.x = ±0.25 mm and x.xx = ±0.12 mm, unless specified.

Operating Conditions

Fiber assemblies with stainless-steel (SS) sheathing and metal end tips: -140° to +249° C

Fiber assemblies with PVC sheathing and/or plastic end tips: -40° to +105° C

Special order assemblies with SS sheathing and metal end tips and model suffix “M600”: -140° to +315° C*

Special order assemblies with SS sheathing and metal end tips and model suffix “M900”: -140° to +480° C*;

note dimensional changes from STD models

* sensing end tip only

APPLICATION NOTES AND WARNINGS !

The ends of glass fiber optic assemblies are optically ground and polished. Care taken in this

manufacturing process accounts for the light coupling efficiency of the fiber optic assembly. As a

result, glass fiber assemblies cannot be shortened, spliced, or otherwise modified.

Use caution when applying fiber optics in hazardous locations. Although fiber optic assemblies

are, by themselves, intrinsically safe, the sensor and associated electronics must be LOCATED IN A

SAFE ENVIRONMENT. Alternatively, fiber optics may be used with sensor model SMI912FQD (page

32). This sensor is approved for use inside hazardous areas when used with an appropriate intrinsic

barrier. Also, see NAMUR sensor models Q45AD9F (page 152) and MIAD9F (page 86). Fiber optics do

not necessarily provide a hermetic seal between a hazardous environment and the safe environment.

In applications where glass fibers to insulate the control from high voltage, specify silicone rubber,

Teflon®, or high-density polyethylene sheathing with no reinforcing wire in the cable. It is the

responsibility of the user to test each fiber optic assembly for insulation capacity.

Do not subject the fibers to sharp bends, pinching, repeated flexing or high levels of radiation.

When ordering fiber lengths in excess of 1 m, take into account light signal reduction of 5 percent per

300 mm of additional length.
