Operating parameters
Factors (boundary conditions) that affect the operational sequence and the function of systems and devices. These include the load curve, behaviour, installation conditions, operating conditions etc.
Locking cylinders
In hydraulic systems, locking is required primarily for safety aspects (aircraft landing gear, lifting platforms, etc). Additional equipment is also used, such as locking units ( Figure V 15 a ) or cl
Power characteristics graph
Graphic representation of a curve showing all the variables which influence the power delivered by a hydrostatic transmission (e.g. torque, efficiency, slip) in relation to another variable (e.g. rota
Incremental digital measuring system
Counting-only measuring system in which first a reference point must be moved to such that a specific position can be determined by counting increments forward or backward (Figure D 29) . The position
Sealing lip
That part of a lip seal that generates the preload during installation (Figure D 13) . On compact seals the sealing lip is often shortened to form a sealing edge.
Electronic filter
Electronic circuit that separates the useful portion of a signal (e.g. measured signal) from the superimposed interference. They are either part of other measuring instruments (e.g. measuring amplifie
Corner frequency fE
On systems that correspond to a 1st degree differential equation, the corner frequency is the intersection of the horizontal asymptote with the asymptote on the falling branch in a Bode diagram (see a
Signal switch
Electrical arrangement to split an input signal into two .
Safety regulations
Separate regulations apply for the particularly dangerous accumulators: DIN 24 552 Hydraulic accumulators in hydraulic systems, AD data sheet A2 Safety equipment to prevent overpressure; safety valves
