Installation
A hole in the cladding should be formed to enable the AT-S probe, ambient gas probe, and thermocouple to
emerge approximately radially from the pipe or vessel. A 60 mm cavity such as one for UT inspection ports is
often suitable, together with a rubber bung with a radial slit through which the probe capillaries and
thermocouple lead emerge.
Installation of sample conduit
Fixing of probe conduit bracket
It is unlikely that the sample conduit, routed from the probe to the analyser, is of exactly the correct length.
Generally it is preferable to loop spare conduit at or near the analyser terminus and to work from the secured
probe towards it.
The probe bracket is affixed to the 10 m sample conduit and must be secured to enable the AT-S, ambient
gas probes, and thermocouple lead to be attached to it. Generally, it will be necessary to fix the bracket to
outside of the pipe cladding. The probe bracket may be banded, riveted or bolted into position. It is
important to ensure;

Secure support for the probe bracket, as it prevents forces being loaded onto the probes if the
conduit is tugged.
