Source Module; Sample Cell - Teledyne 6600 Operating Instructions Manual

Oil in Water
All sample-filtering (fluid) components are located on the same side of the
equipment panel as the electrical components.
3.1
The photometer control/analysis unit module is mounted on a back panel.
Modules for General Purpose; I, II, B, C & D; and I, I, B, C & D are avail-
able and mounted within sheet metal Nema enclosures as well as Nema
stainless enclosures depending upon customer preference for the intended
environmental areas. These enclosures are either Z-purged or X-purged to
meet hazardous area classifications. In some cases, Teledyne has supplied
non-purged, Division II Oil in Water systems self-certified to FM standard
3600 for non-incendive equipment and ISA S12.12-1994 standard for the
same type equipment (Class I, Div II, B, C, D).
3.1.1
The source module contains a mercury-line lamp (the source of UV
energy) located within a parabolic reflector which captures most of the emitted
lamp output energy. A quartz lens is used to focus the energy into a beam for
transmission through the optical path and sample cell before reaching the
detector (PMT).
WARNING:
The lamp is installed within a parabolic reflector. It emits strong UV
radiation. When the module is opened with the lamp on, UNDER NO
CIRCUMSTANCES SHOULD THE OPERATOR VIEW THE LAMP
DIRECTLY OR BE ALLOWED TO OPERATE THE UNIT UNLESS
PERSONNEL IN THE IMMEDIATE VICINITY ARE PROTECTED WITH
SUITABLE UV ABSORBING EYEGLASSES.
3.1.2
All systems, the Aluminum/CPVC sample cell couples the source and
detector modules together along a folded optical train of the photometer. The
sample cell includes double windows (inner sapphire, outer Quartz), at either
end, to prevent condensate from forming in the optical path.
