Measured variable
Physical variable whose value is to be determined via measurement.
Load stiffness
Ability of a system (e.g. of a hydraulic drive) to yield as little as possible under an external load. Load stiffness for linear drives is mostly stated in N / μm. It can be compared with spring stiff
Charge amplifier
Device which converts the electrical charge associated with a measuring instrument into a voltage signal and amplifies it in accordance with the piezoelectric effect.
Digital measured signal
With a digital measured signal the unlimited number of values of the measured variable faces the limited number of values of the measured signal . A value range for the measured variable is therefore
Piston motor
The radial piston motor tends to predominate with its special pneumatic motor variety. The piston motor supports high loads across all rotation speed ranges and is particularly suitable for low rotati
Indication range
Range of measured values that can be read on a measuring instrument. This range is not necessarily identical to the measuring range .
Over-excitation
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
Sensor
Primary element of a transducer, which directly determines the measured variable and converts it into a mechanical or electrical signal suitable for further processing. In practice, the term sensor is
Primary control
In a hydrostatic transmission , the pump can be adjusted and the motor is associated with constant displacement . The drive rotation speed is therefore proportional to the flow rate for the pump, i.e.
Labyrinth seal
Seal type for sealing rotating areas based on a gap seal whereby the gap length is increased by the contour of the gap assuming a meandering or zigzag pattern ( Figure L 1 ). Labyrinth seals — mainly
