Before beginning installation, ensure that the gasket is in good condition and that the sealing
faces are not scratched or dented.
Support the cradle such that it aligns the probe with the flange port that it will be fitted to. Avoid
applying stress to the probe, weld, or flange by ensuring that the sealing face of the hub sits
flush against the gasket and sealing face of the mating flange before fitting any mounting bolts
to the flange.
The cradle has lifting points to assist in locating: two either side of the cradle at the front and
one located through the base plate at the back. The cradle also has 4 mounting points through
the base.
5.6.3. Maintenance
Keit recommends regular inspection of the integrity of the welds on the front and rear in line
with local safety procedures.
Inspection of the sealing weld will require removal of the flange and spectrometer from the
pressure vessel and can be completed as part of regular inspection/maintenance of the
spectrometer and pipework.
Do not use impact (e.g. a hammer) to separate components if the gasket becomes stuck to
the flange and hub.
The lap-joint flange may be manufactured from Hastelloy or stainless steel. Care should be
exercised to ensure that it is not corroded by aggressive chemicals during maintenance or
installation.
5.7. Inclined Stand
– ASM0916
The inclined stand is designed for using the spectrometer as a bench top instrument for offline
sampling. Angled at 35°, the probe can be positioned into beakers or other vessels for ease
of use. It can also be configured for two heights to give added flexibility in how it is used.
