Position measurement
when measuring the length of a path travelled. For path or position measurement, the location of a point is measured in relation to a fixed point of reference. In measurement technology position measu
Telescopic connection
Arrangement of two pipes which are sealed off against one another and can be axially adjusted into one another. Telescopic connections are used with axially movable cylinders in place of hoses.
Discrete
Comprising individual elements, not contiguous. In control technology a process is discrete if it takes place in steps.
Valve block
Arrangement of several directional valves including pressure and control valves in a single block (monoblock valve) or individual valves screwed together (sandwich valve). Valve blocks are used as a m
State variable
If the transfer function of a system is described by state equations , this results in a set of first order differential equations, each of which respectively links the input and output of an integrat
Timer element
A distinction is made between: Binary timer elements: Switching element, which passes on binary input signals at a different time; Delay element: Timer element, which reflects the change of the input
Step diagram control
Form of process-dependent workflow control, in which the switching conditions depend only on position-dependent signals of the controlled system (according to DIN 19 237).
Valve polarity
Ratio between the direction of the controlled hydraulic fluid flow and the direction of the electrical input flow for continuously adjustable valves.
Large signal range
Operating range of a continuously adjustable valve with high performance, i.e. more than 50 % of I nom, as is necessary for moving to a point or reversing the direction. Opposite: Small signal range
