Electric feedback
General : The controlled or auxiliary variable (e.g. distance, force, speed among others) necessary for a specific result is converted into a corresponding signal that is fed back to the input on the
Signal selector
If a signal is adjusted continuously or in steps, the term signal selector is used. As the reference variable is to be set such that the task variable reaches its setpoint, the signal selector for the
Set pressure pe
General : Pressure set on a device (DIN 24 312). On pressure-limiting and safety valves (DIN 3320): set pressure p e is the pressure at which in test stand conditions (atmospheric back pressure), dire
Adjustable displacement pump
Variable pump on which the geometric displacement can be set (limited) to a specific flow rate . This setting is made, e.g., by means of a stop screw that fixes the pivoting of the cylinder drum to a
Clamping pressure
Pressure p A or p B in the operating ports A or B with a load that is not subjected to load and hydraulic zero. The clamping pressure is then equal to half the sum pressure . This statement does not a
Settling process
Process in a system/device during the transition phase to achieving a steady-state if the system/device has been excited by a step function . The settling process therefore shows how a transfer elemen
Tolerance of unit step response
Difference between the largest and smallest permissible deviations of the from the limit (DIN 19 226 Part 2).
Settling time of pressure
Time that is required for a sudden change in the operation pressure with a pre-defined deviation to settle.
Male fitting
Pipe connection that can be undone and that is designed at one end to screw into a device bore ( pipe fitting ).
