5.3 Principle of operation
The sampling cycle from a ILS Guillotine sampler:
•
The sampler is in standby position , the plunjer has its cavity above
the outlet.
•
When the actuator is driven by compressed air the plunjer will
“shoot” inward the piping and the cavity will fill with medium (
fill
position
).
• After several seconds the plunjer shoots back in the enclosure and
medium from the cavity drains through the outlet. After draining
the sample the sampler goes back in to
standby position.
5.4 Installation instructions
See fig. 5.4 for installation instructions. Keep in mind:
• Place sampler in a 100% filled pipe free from air inclusion and in
horizontal piping with a minimum flow velocity of 0,5/s.
• Ensure there is enough height for the silicon hose which enters
the inlet in the enclosure.
• Do not place the sampler in turns or reduces.
• For safe maintenance and reparations the sample pipe needs to
be empty.
•
Don’t place the sampler in or after a downward flow.
•
Maximum pipe pressure 2 bar.
•
Ensure the sampler doesn’t stick in the piping in standby position.
