Series connection, in which one output is connected to the input of the next element. In the case of series circuits with resistors in the same way as the electrical engineering, the individual resist

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

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

Where there is friction, there is wear. This also applies to seals . Here the wear depends on: The system pressure (seal is pressed against a surface); The surface roughness of the sliding surfaces (R

Air Cleaner Fine Test Dust (ACFTD)

Of the most important forms of energy that can be used for drives (mechanical, hydraulic and pneumatic) only mechanical energy does not require conversion (Figure E 29) . For all forms of energy the d

Memory programmable control with read-only memory as program memory with content that, after successful programming, can only be changed by mechanical action in the controller (DIN 19 237). The contro

Device on valves to control the position of the switching element and therefore the functionality of the valves. The position monitoring is commonly performed using proximity sensors or displacement t

The speed of hydraulic cylinders is calculated from the flow rate Q, the effective area of the cylinder A (extend speed - piston area , retract speed - annulus area ) and the number of cylinders ic. C

In a digital control with signal hold, the value achieved for the output variable is retained following removal or withdrawal of the reference variable — particularly following termination of the trig
