5.3.2. Installation
The sealing face on the probe requires a gasket to mate against the flange on the process
pipework. The gasket material must be chosen to be compatible with the pressure and
temperature range of the process media and must be chemically compatible.
WARNING
Choice of gasket material must be appropriate for the chemistry
and process being used.
The probe body and hub are manufactured from Hastelloy as standard, which is resistant to
many aggressive chemicals.
However, you are advised to check with Keit before
installing on a new process.
Before beginning installation, ensure that the gasket is in good condition and that the sealing
faces are not scratched or dented.
Support the spectrometer on a suitable mounting frame that 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.
