Fluid friction
Friction in a hydrodynamic or hydrostatic load bearing, liquid or gaseous, continuous layer. In the hydrodynamic load-bearing layer, the pressure in the layer is produced by the movement of the bodies
Filter life
This parameter, which would be very important for the user, depends on so many boundary conditions that it can, at best, be estimated if the operating conditions are known.
Error curve of measuring instruments
Graphic representation of the error as a function of the output (indication). The error behaviour can also be defined in a table (Figure F 5) (VDI 2600).
Switch-on time
Time a system requires to reach the steady operating state from the switched off state.
Pressure oscillation
Oscillation in a pressure fluid that is caused by pressure pulsation.
Rotary pipe joint
Element for connecting pipes that permits rotation at the joint (Figure D 36) . Rotary pipe joints are required wherever hydraulic energy must be routed from a stationary part of a machine to a moving
Digital cylinders (with several positions)
Cylinder design that is equipped with several, mostly binary tiered pistons that can be operated in any combination. Therefore with n pistons 2n-1 positions are obtained with a positioning accuracy th
Carrier sense multiple access with collision detection (CSMA/CD)
Monitoring process for buses with access without a defined sequence. Access collisions are detected. fieldbus
Binary
Two specific, mutually exclusive states, e.g. yes/no, correct/incorrect, on/off, O/ L or 0/1. The binary numerical system has the base 2. With n binary signals it is possible to define 2n states. Ther
One-way trip
Device for actuation in only one direction. In the other direct there is no actuation (CETOP RP 100).
