Refers to a configuration whereby the output variable (e.g. velocity) is not dependent on the load, but only on the target value. A distinction is made between: exact position-dependent locking proces

Determination of the ongoing position change of a functional element on an axis (e.g. the piston of a cylinder or valve ) and feedback for processing in a closed circuit position control system . The

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).

A distinction is made between analogue and digital processes ( Figure W 6 ). In analogue position measurement processes, the resistance position measurement (with potentiometer) is commonly used for l

Overload protection helps secure the system against excessive operating pressures. In fluid technology, the overload protection is provided by the working method of the pressure-limiting valve, which

The law of superposition states: If an input variable (xe1) brings about an output variable (xa1) and also another input variable (xe2) brings about an output variable (xa2), therefore: if the law of

Describes the change of an over time when adding characteristic curves of the input signal (DIN 19 226) ( Figure U 5 ). The step function is a characteristic change of the input signal . . The or is t

Part with internal and external thread to connect two with different diameters.

To reduce the switching time (or to increase the stroke force) in the case of DC solenoids, the operating voltage is increased up to a factor of two. To prevent damage to the solenoid, however, the sw

Difference between an absolute pressure p abs and the respective absolute atmospheric pressure p amb ( Figure U 3 ). The overpressure takes on a positive value if the absolute pressure is greater than
