Newtonian fluid
Fluid where the shear stress is proportional to the velocity gradient dv/ds: The proportionality factor η is referred to as the dynamic viscosity . Mineral oil is a Newtonian fluid, whereas lubricatin
Cascaded (multi loop) control system
Also referred to as multi-loop controllers, these are controllers where, in addition to the actual controlled variable such as the position, one or more other variables such as the velocity and/or acc
Filter element
The part of a filter that undertakes the actual filtering action. Filter elements are generally designed so they can be replaced easily and are disposed of after use (exception: metal filters). The ti
Word
As opposed to a Byte, which contains 8 bits, a word is a group of as many bits as a certain type of computer can process in parallel. As a rule, this is the data bus width. Therefore, in an 8-bit proc
Segment pressure compensator
Individual pressure compensator
Submerged motor
Electrical drive motor for pumps, which is installed beneath oil in the tank and therefore does not require a closed housing or whose housing also performs the tank function, particularly in the case
Integrated control
Increasingly, individual devices are tending to feature internal with a view to preserving or improving certain characteristics. Typically with integrated controls, the controlled variable tends be an
Dead time
Time, which passes after the input signal is changed, without changing the output signal.
Filter with bypass valve
Filters that provide a bypass for the flow rate around the filter, if the has reached a defined value. The filter function is then disabled, such that its effectiveness is reduced (Figure F 11) . The
