Safety lock
Lock, which primarily serves to protect humans and/or machines. It is normally placed in the individual control level or on the .
Tie-rod-cylinder
Cylinder , in which the lid and bottom are connected to the cylinder tube by a tension rod (Figure Z 7). The tie-rod cylinder is cost-effective. It is used in hydraulic systems at low pressures.
Safety of a system
In general : The term "safety" should only ever be used within the meaning of preventing a risk primarily to people and not within the meaning of the reliability of a system (cf. operating safety). Th
Positioning error
Errors which (may) occur when positioning hydraulic drives. They consist of; the Δs N, errors associated with hysteresis and the reversal error for the continuously adjustable valve (between 0.1% and
Sound in fluid
Sound that propagates in a fluid medium. It can have been, but has not necessarily been generated in the fluid. The propagation velocity for mineral oil in steel pipes is approx. 1,300 m/s.
Dead zone compensation
Underlap compensating signal
Resistive measurement
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
Erosion wear
Material removal that occurs in hydraulic devices at the points where the hydraulic fluid impacts at high speed. Erosion wear comprises cavitation erosion and particle jet erosion and is material depe
