fan is equipped with a diff erential pressure sen-
sor, connected to the controller.

48 to 120 = 0 - 3000 Pa and a signal of 0.5 - 4.5 Vdc.
The pressure sensor measures the static pressure diff erence before the
suction chamber and in the suction cone.
The air fl ow can be calculated according to the following equation: Qv =
K x √∆Pa
Qv fl ow in m
