Measuring procedure, in which the change of the specific electrical resistance of a conductor is determined using the force or deformation and converted into a measured signal . Example: Piezoresistiv

Repeatability

Characterises the number of particles present in hydraulic fluid . Purity classes are stated either in filter classes according to NAS 1638 — which specifies the permitted particle numbers in five par

Series connection, in which one output is connected to the input of the next element. In the case of series circuits with resistors in the same way as the electrical engineering, the individual resist

Hydraulic pump with pistons arranged alongside one another and perpendicular to the drive shaft Piston ( Figure R 24 ). They are preferably made as single-piston pumps (also for manual operation) or a

Sealing friction

The resistance that opposes the relative movement of surfaces in contact with one another. Friction is the main cause of the unwanted conversion of mechanical energy into heat and therefore energy los

Depending on the relative speed of the contact area and the lubrication condition, the friction displays non-linear behaviour, which can be attributed to characteristic mechanisms of action. A distinc

The energy irreversibly converted due to the friction, which is removed from the system in the form of heat. In fluid technology, these losses occur due to friction as a result of the viscosity of the

The differential pressure required to move a piston without an external load – i.e. to overcome the friction Differential pressure under defined conditions in the cylinder chamber.
