Mounting
The
mounting rail
on the bottom case is for the stable take-up of for ex-
ample of a ball and socket mounting (for fiber optics devices a mounting
angle is recommended, see
)
Front M5
threaded holes
can also be used for mounting (all 4 threads
has to be used for fixing).
The slightest deviation from the optical axis is achieved with the
optics
adapter/holder
of motor focus and fixed focus devices.
Note that the
installation
of the pyrometer is free of vibrations, if neces-
sary, helps the use of rubber absorbers when mounting.
To keep the
optical fiber
ready for use as long as possible, it should be
exposed as little as possible to permanent movement and mechanical
stress. Lay the optical fiber as possible with a large bending radius, especially if it is carried along
moving parts.
During installation of the optical fiber, it is advisable that both plug ends are not yet connected to the
pyrometer and the optics. Tensile and torsional stresses are to be avoided.
INFO:
Through manufacturing tolerances the optical and mechanical axis are not running 100%
in the same direction. The pyrometer should be realigned if it is installed again and twisted in
the same holder (see
Alignment onto the measuring object
).

Mounting Optical Fiber / Optics
(only devices with optical fiber)
5.2.1 Bending Radius Optical Fiber
The color code on the optical fiber identi-
fies the optic diameter and minimum bend-
ing radius associated.
When laying the optical fiber it is to ob-
serve the minimum bending radius. A
bending radius smaller than the specified
can cause a stretched or broken optical fiber.
5.2.2 Winding and Unwinding the Optical Fiber
During winding and unwinding the optical fiber must be able to move easily
and should not be twisted. Ideally, one hand winds up the light guide careful-
ly, while the other hand guides the cable roll. For torsion-free winding only
one side of the optical fiber should be connected, than the other can be
moved freely.
NOTE:
Strong tensile and torsional forces during rolling and
mounting should be avoided.
5.2.3 Mounting of Optical Fiber
Assignment fiber to pyrometer and optics:
Each fiber is uniquely associated to a pyrometer and op-
tics. For identification, all three components are tagged with the same device number. The measure-
ment accuracy can on-
ly be guaranteed with
proper assignment.
