Mounting for equipment monitoring
When mounting equipment-monitoring systems (EDP installations, electrical cabinets etc.), plastic tube materials are always to
be used. Further, the same guidelines as described in Sec.
2.5.6 apply.
All air outlet openings of the monitoring devices have to be used for equipment monitoring. Please note that an ASD 535 can
be fitted with a maximum of six sampling fixtures.
Whenever possible, sampling pipe and detector housing are always fastened directly to the object to be monitored.
2.5.7.1
Screw-free fastening of the sampling pipe
For screw-free fastening of sampling pipe parts (sampling fixtures) the click pipe clamps are used. This makes it possible to
quickly remove the sampling fixture or the sampling pipe during maintenance work on the monitored objects.
The click pipe clamps are screwed onto the support rails by means of threaded plates.
The support rails are best fastened at a right angle to the pipe axis to ensure precise positioning of the sampling pipe (sam-
pling fixture).
Double-sided adhesive tape is used to fasten the support rails in the desired position on the object,
Prior to using the double-sided adhesive tape, the adhesion surfaces should be cleaned with a
non-aggressive
cleaning
agent (e.g. soap suds or similar).
Using a cable binder instead of the double-sided adhesive tape is also possible.
