5.4 Measuring or displaying the back pressure /
differential pressure
If pressure measurements are carried out in a hydraulic sys-
tem, the type of measurement such as the back pressure or
differential pressure and also the measurement point are cru-
cial, as shown below.
Fig. 18: Measure or display dynamic pressure / differential pressure
∑p = Total of the pressures
∆p1 = Differential pressure
∆p2 = Differential pressure
∆p3 = Differential pressure
∆p4 = Differential pressure
In the example, the back pressure at the first measurement
point shows the total of the subsequent pressures in the hy-
draulic system.
