Mounting for equipment monitoring
When mounting for equipment monitoring (EDP installations, electrical cabinets etc.), plastic tube materials are to be used in
principle. The same guidelines as described in Sec. 5.5.6 apply.
Equipment monitoring involves monitoring all the air outlet openings of the monitored devices.
Whenever possible, the sampling pipe and detector housing are always secured directly to the object to be monitored.
5.5.7.1
Screw-free fastening of the sampling pipe
Use the click-on pipe clamps to secure the sampling pipe parts (sampling fixtures) without screws. This allows the sampling
fixture or sampling pipe to be removed quickly during maintenance work on the monitored objects.
The click-on pipe clamps are screwed onto the support rails by means of threaded plates.
The support rails are best fastened at right angles to the tube axis to ensure a precise positioning of the sampling pipe (sam-
pling fixture).
Double-sided adhesive tape is used to secure the support rails in the desired position on the object,
Before using the double-sided adhesive tape, make sure the adhesion surfaces are cleaned with a
non-aggressive
cleaning
agent (e.g. soap suds or similar).
Cable ties can also be used for securing purposes instead of the double-sided adhesive tape.
