Dynamic pressure principle for flow rate measurement
Flow rate measurement of the Bernoulli force of a flow rate on a body, e.g. a Prandtl tube ( Figure S 78 ). This is then used to measure the static pressure p 1 and the dynamic pressure p 2 and thereb
Static behaviour
Describes the connection between the output and input variable of a transfer element, i.e. after all of the settling processes have ended. It therefore describes the stationary state of the system. Th
Static parameters of continuously adjustable valves
The static behaviour of a continuously adjustable valve describes the connection between the input variable and the output variable of the valve for the stationary state after settling. This includes
Static seal
Seal intended to seal a non-moving surface. Although the expression is often used, it is incorrect, as the seal is not "static", but only seals a non-moving surface.
Continuously adjustable pressure valve
Valve with a proportional connection between the input signal and pressure in the working lines (consumer ports). This includes construction designs of proportional pressure-limiting valves and pressu
Squeeze stress in seals
Stress, which occurs where the moved surface runs against the sealing lip , i.e. the frictional force on the sealing surface and the compressive force are working in the same direction. The friction i
Adjustment time
Time at which the correcting variable runs through the correcting range at the maximum considered correcting speed (DIN 19 226).
Control characteristic
Transfer function of the subsystem with respect to changes to the correcting variable (DIN 19 226).
Correcting variable
Output variable of the controller or and also the input variable of the subsystem. It transfers the controlling effect of the device to the subsystem (DIN 19 226).
Correcting speed
Speed, at which the correcting variable is changed (DIN 19 226).
