● The detector should not be
mounted in areas where it can be
drenched by water.
● Also, the fact that gas quickly dilutes
when released into the air, and the
impact of wind must be considered.
As illustrated below with a leak
point at position A, the gas will
spread in the direction of the wind
and be detected at position C (down
stream), but not detected at
position B. The wind speed has no
effect on the detector.
3.3 Mounting the detector
Below, PG11 is shown securely mounted with M8 mounting screws, nuts and washers. The
PGE11 is mounted with the same solution.
PGxx11 should be mounted with the longitudinal axis in the horizontal direction as illustrated
below. At the same time, it can be rotated in any direction around this longitudinal axis. The
reason for these requirements is that such a position will reduce the accumulation of
contamination on the optical parts (lens and mirror).
