5.4.1. Safety
WARNING
The port tube forms a seal with the process pipework and as such
are safety critical to prevent an accidental discharge of the
process media. Keit recommends regular inspection of the
integrity of the welds in line with local safety procedures.
CAUTION
The spectrometer weighs ~18kg. The port tube must not be used
to support the instrument on process pipework. Doing so risks
damage to the spectrometer and excess stress on the piping
system.

5.4.2. Installation
After mounting the port tube using the welding points directly to the pipeline, the probe is
inserted through the port tube, sealed using an O-ring in the narrower O-ring groove.
If the IRmadillo is not going to be installed into the pipe immediately the blanking plug can be
positioned with the grooved side aligning with the rear of the port tube. This is held in place
using the sanitary tri clamp.
Support the spectrometer on a suitable mounting frame that aligns the probe with the flange
port that it will be fitted to. The probe is inserted through the port tube; it must have a O-ring
positioned in front of the clamping groove to seal.
5.5. Port Flange - ASM1486
The flanged version of the port tube accessory allows connection to process pipework with an
ANSI/ASME B16.5 or EN 1092-1 compliant flange for continuous analysis of your process.
It is fixed in place using a tri clamp that locates over the rear of the port tube and two semi-
circular collars that fit around the probe; the clamp does not need to be tightened with
significant force. A blanking plug is also provided to seal the end if the spectrometer is
withdrawn from the pipeline. For technical drawings, contact Keit at enquiries@keit.co.uk.
