OPECL modules must be affixed to a solid, non-vibrating
structure capable of supporting a minimum of 100 lbs (46
kg), located within the system’s rated separation distance.
A building wall, a heavy steel I-beam, or nearly any type
of masonry typically provides the most rigid mounting
surface available. However, avoid the use of wood
structures or supports if the possibility of warping exists.
When using a vertical post, the post must be absolutely
stable and without vibration. Square stock pole is
recommended. Mounting height should not exceed 3
meters.
The post can be set into the ground or attached to a
secure surface. If a post is set into the ground, the
portion below grade should be set in concrete at least 1
meter deep.
Important
In all cases, consider whether additional bracing
or support is needed to ensure the structural
integrity of the module installation. See Figure
4. Remember that accurate module alignment is
essential for proper performance of an open path
gas detection system, and
even a small amount
of movement can have a detrimental effect on
alignment. This is especially true for installations
with significant module separation distances.
