5.2 Measure or display dynamic pressure / differential
pressure
If pressure is measured in a hydraulic system, the type of mea-
surement such as dynamic pressure or differential pressure
as well as the measurement point is critical, as shown in the
following diagram.
Fig. 10:
Measure or display dynamic pressure / differential pressure
∑p = Total of the pressures
∆p1 = Differential pressure
p1 = Back-pressure
∆p2 = Differential pressure
p2 = Back-pressure
∆p3 = Differential pressure
p3 = Back-pressure
∆p4 = Differential pressure
p4 = Back-pressure
In the example, the back pressure at the first measurement
point shows the total of the subsequent pressures in the hy-
draulic system.
