Durchflussverteilung (Flow Sharing)
determined by this pressure compensator can be compared directly with the value of a second valve, which allows a proportional readjustment between both valves. This can be achieved by a mechanical-hydraulic [...] fluid will choose the path of least resistance if the pump cannot provide the required flow. This can result in the valve with the lowest pressure receiving even more flow than required, while the other
Twin filter
Combination of two filters with a control unit so that the entire flow rate can be passed through one of the two filters while the other can be cleaned. (Figure D 32)
End position damping
used to reduce the speed of a piston before the end of its stroke. The damping can be mechanical or using a fluid; a choice can be made between fixed or adjustable ( Damping of cylinder motion ).
Supporting ring
in its installation nut. Supporting rings are made primarily of elastic materials and can be loose in the seal or can be vulcanised into the seal ( Figure S 109 ).
Code
into a different form while maintaining the information content. A code can also be a code for an agreed character set that can be used for calculations in a computer system.
Sources of error in measuring instruments
addition, there can be external effects such as temperature, humidity, position, acceleration among others as well as interfering electric fields. Finally incorrect attachment or handling can cause errors
Reprogrammable control
Hard-wired control, in which program changes are provided for and can be performed in a simple manner. These are controls whose program can be changed, for example by reconnecting lines, changing or replacing
Differential pressure gauge
Device that measures the difference between two pressures. This can be a pressure gauge with display or an electrical output. It can also be a device based on a or a piezoresistive system that either indicates
Temperature measuring device
temperature or temperature difference of a medium. The measured value can be read directly (e.g. in the case of a liquid thermometer), but can also be fed to a display unit as an electrical variable. In this
Torque measurement
The most common methods use measuring shafts and . They can measure precisely, however, the measured variable must be tapped via sliding contacts or wirelessly. Conversely, with hydraulic torque measurement [...] measurement the torque is converted directly into pressure that can be read on a pressure gauge . Their accuracy and suitability for dynamic measurements is lower.
