Operation Principle ILS 3WP SS
The sample cycle of the ILS “3W” sampler works as followed:
• Standby position sampler, the sample bullet has its cavity pointed
to the sample outlet.
• After closure of relay contact K1 (see diagram §1.7) the sample
ball will rotate towards flush position and will stay there as long as
contact K1 is closed. At this point the sample ball makes a passage
between supply inlet and flush outlet:
flush position .
•
When contact K1 opens, the sample ball will rotate back towards
its rest / drain position. The sampled medium will stay in the
sample pipe.
• Rest / drain position and the sample pipe will drain empty.
