Permissible Values for Laying the Sample Gas Line
Avoid bundling or laying several
heatable sample gas lines, so that
they touch each other. This results in
overheating at the contact points.
Do not squeeze the heat insulation in
mounting brackets tightly together,
so that the outer braiding is pressed
on to the heat conductor. If you
disregard this, damage to the
protective braiding and the heatable
sample gas line may occur.
Comply with the following values when laying the heatable sample gas
line:
Characteristic
Maximum line length
Minimum bending radius
Maximum clip distance
Lowest laying temperature
Temperature of the sheathing
Lay several heatable sample gas lines
separately with a distance of at least
2.5 cm and provide adequate ventilation.
Heat can be conducted away as a result.
Tighten the BBS cable clips sufficiently
but not excessively, in order to prevent
damage to the protective braiding and the
heatable sample gas line.
