Installation
The cladding joints and probe exit from the cladding should be sealed with a suitable sealant to prevent the
ingress of water. This arrangement has a number of advantages:

The insulation around the probe is isolated from the general equipment insulation by the cap. This will
prevent / reduce water that gains access through damaged cladding from penetrating to the area of the
probe.

When inspecting the integrity of weather protection only the short section of insulation needs to be
inspected.

When repairing the cladding, checking for water ingress or inspecting the probe only the short section
needs to be opened.
The test site should be insulated and clad with the probe thermocouple and AT-S probe now in place. Note
that the AT-S probe and ambient gas probe caps should not be removed during this procedure; in order to
prevent insulation debris and fibres from entering them. The probe capillaries will withstand flexing to about
2" radius; however, flexing of the thermocouple lead should be minimised. It is essential that the AT-S probe
plate remains firmly in place, and is not distorted by tugging of the capillary conduit.
Make sure the probe cap is in place. The free ends of the probes and sample conduit should either be
pushed through a hole in the insulation as it is laid over them, or a slit can be made in the insulation to
accommodate them.
