∆ p-Measuring Range
Example: The filter is to be cleaned at a differential pressure of 60% of the  P measuring range
with a pause time of approx. 25 sec.
Selection of the characteristic curve: The intersection of the curves '60% of the
measuring range' and '25 sec.' is on characteristic curve 60. The pause poten-
tiometer is set to 60 sec.
The control system controls the pause time along characteristic curve 60. The cleaning
capacity is increased progressively due to the shape of the characteristic curve.
Additionally, a larger amount of dust per impulse is cleaned if the differential pressure is
higher (= higher resistance of filter).
For shorter pause times, the capacity of the pneumatic system must be considered.
