If an elastic material (elastomer or specific thermoplastics) is excessively deformed under pressure, lasting deformation may be caused such that after the end of the pressure action only part of the

Difference between the setpoint and actual value of the control variable . It is positive if the actual value is smaller than the desired value. A differentiation is made between: a residual control e

In a predetermined valve this is a factor of the size of the flow: the smaller it is, the greater the deviation from the desired value. ( Figure T 6 ). Flow dividers based on displacement units (e.g.

Collective term for the area of electronic processing and control technology that operates with digital signals with the characteristic that the numerical input signals in turn correspond to numerical

On cylinders a differentiation is made between four different types of motion that affect the structure of the drive: Transport motion : with the highest force required on accelerating the load. The v

Device for angle measurement (indirect travel measurement). It receives the travel pulses generally via a spindle-nut system and converts them into the rotation of a graduated disc that is scanned pho

Contact seals for fluid technology are predominantly manufactured from polymer materials in the group "elastic materials". The most important characteristics of these materials are their elasticity (a

Designates the oscillation of a system capable of oscillation, which is linked to another or is otherwise periodically stimulated. In the case of poorly damped systems close to the natural frequency ,

Entirety of (pressure) losses caused by a flowing medium. These primarily consist of the (cross-section independent) pressure losses , but the friction losses also contain an element, which is caused
