Figure 2.15 Pipe system components
During planning/design, a distinction is drawn between area monitoring and equipment
monitoring. For both applications, PVC pipes and halogen-free pipes can be used. The pipes
used for equipment monitoring should be halogen-free.
Figure 2.15 shows essential accessory components that can be selected for the application
concerned.
The pipe system must be constructed using pipes with an external diameter of 25 mm and the
associated fittings.
blowing-out system
In areas that are susceptible to dust particles or icing, it may be necessary to blow out the
aspiration pipe system and its air sampling openings. Figure 2.16 shows a manual blowing-out
system with a three-way tap.
