Procedure for Laying the Sample Gas Line
incorrect correct
Do not lay the heatable sample gas
lines directly side-by-side in an
enclosed duct or shaft. This results in
heat accumulation.
Ensure that the hoses do not touch.
Maintain a distance of 25 mm. Provide
adequate ventilation. Heat can be
conducted away as a result.
Prevent powdery substances,
adhesives or other thermally
insulating materials from soiling the
heated sample gas line. Otherwise,
overheating will occur at these
points.
If soiling occurs, clean the materials and
remedy the cause. Heat can be conducted
away again as a result.
Avoid heat accumulation through
wrapping the heatable sample gas
line with other materials, otherwise
the sample gas line will overheat at
these points. Do not cover the area
near the temperature sensor,
otherwise the rest of the sample gas
line will cool down.
Do not wrap the sample gas line. Ensure
that the area near the temperature sensor
is exposed. This results in error-free
temperature measurement.
Do not lay the heatable sample gas
line in wall break-throughs which are
subsequently sealed with a sealing
compound under any circumstances.
The sample gas line will be destroyed
by overheating in this case!
When laying the heatable sample gas line
through a wall break-through, use
bulkhead plates with conduit thread cable
glands, in order to provide adequate
cooling of the sample gas line.
