5.4 Process flange Clear Aperture

The Launch and Detect unit flanges (and insertion tubes if used) should be installed in such a way that a

minimum clear through aperture (opening) diameter of 1 ½” (38 mm) when the distance between the 2” 150#
flange faces does not exceed 6ft (~2 m).

Note: Larger clear through apertures may be required when operating over longer distances –

CONSULT FACTORY for further details.

5.5 Mounting the Launch and Detect Units to the Process Flange

Securely bolt the Launch and Detect Units to the process flanges using the standard bolt holes provided. Ensure
the correct size bolts, nuts, and gasket are used in accordance with the flange specifications and in accordance
with the process specifications when applicable.

NOTE: If the process isolation valve flange is excessively hot due to the process temperature or radiant
heat, then a thermal insolating flange gasket should be used in order to minimize the heat transfer to the

analyzer flange face.

It is generally beneficial to make the flange of the Launch and Detect Units and the flange of the process

concentric with each other. Due to the large clearance provided by standard flanges and bolts, it is possible to
mount the two flanges in an un-concentric manner – this should be avoided to aid laser beam alignment.
