Motor stiffness
Relationship between changes in torque at the motor shaft and changes in the angle of rotation ( load stiffness ).
Diaphragm (membrane)
Mostly pre-shaped plates made of elastomer whose task is to form a tight separating wall for a limited volume. A distinction is made between flat, pot and rolling diaphragms ( Figure M 12 ). Within hy
On-off control
Compressor and motor are allowed to run. When the upper pressure value is reached, the compressor switches to idling mode. This is done by providing relief at the pressure side with the suction valve
LAN
A serial bus line for data transmission within a locally restricted area is referred to as a LAN (or also an "inhouse net"). Local networks are the sole responsibility of the user and are restricted t
Measured value
The value determined to represent a measured variable and output at the signal output element . It is expressed as a product of a numerical value and the unit for the measured variable. Compared with
Hydraulic accumulator
Accumulator which stores a fluid under pressure and is therefore able to release hydraulic energy. Pressurisation is mainly based on gas pressure (air, nitrogen, " hydropneumatic accumulator ") and, m
Hamming distance d
Term used in digital signal transmission, signal processing ; measure of the resilience of a code against transmission errors (literature: R. W. Hamming, Error Detecting and Error Correcting Codes, Be
Switching power
Minimum power on the switching element required to actuate a valve (CETOP RP 100).
