Note 1:
Select either analog or switch output
Note 2:
This characteristic is guaranteed within a regulation range between 10 and 90% of the full scale, with
a power voltage of 24V±10%, a supply pressure of 1 bar higher compared with the set pressure (ex.
regulation of 3 bar, supply pressure of 3+1 = 4 bar) and a volume connected to the outlet without any loss.
In applications with great air consumption, such as the blowing, the indicated tolerance may change.
Note 3:
The above apply when working pressure
and control pressure are maximum.
Note 4:
The above apply when working pressure is maximum
and the step is as follows:
50% F.S. -> 100% F.S.
50% F.S. -> 60% F.S.
50% F.S. -> 40% F.S.
