Transfer function φ of a system
If certain requirements are fulfilled in a system with given input variables u and output variables v and all input variables are uniquely allocated to the output variables, this unique allocation is
System-compatible signal
Signal whose are defined for an equipment group (modular system) and which can be processed by all devices of that group without additional measures (DIN 19 237).
Current indicator
Device, in which the movement of an element (ball, vane, etc.) displays the presence of a flow.
Stuffing box
Seal for shafts and spindles (including against high pressures), that uses a tubular-shaped textile sealing material, which is under axial pressure, which, like the radial sealing tension created by t
Sinus response
Change of the output variable over time in the case of a sinus function as an input variable in a steady state ( Figure S 62 ) (DIN 19 226 T 2).
Fluid power standards
Responsibility for working on and drafting standards for fluid technology lies with the specialist fluid technology department at the Normenausschuss Maschinenbau (Standards Committee Mechanical Engin
Modular control
Control system with a modular structure in terms of hardware and software, making it more easily adaptable to variable conditions. Opposite: control with a rigid structure.
Multiple pump
Pump block consisting of several individual pumps with a shared drive shaft. This is achieved by either arranging things axially in a row (where the shaft for the first pump has to transfer all the po
Sound in air
Sounds in air or gases are due to small changes in pressure in terms of time and space ( pressure waves ) caused by disruptions in pressure and are superimposed on the static pressure. They are propag
