Value discrete
The signal parameter can only assume defined discrete values (or overlapping value ranges) (DIN 19 225).
Position-dependent control signals
Electrical signals which are issued depending on the path travelled. Switches with a contacting or –– increasingly –– non-contacting method of engaging through to hall generators. However, optical swi
Control in the power range
This is understood as the part of the overall control system of a plant, which is to control the compressed air or hydraulic fluid. in terms of direction, strength and pressure potential from the pump
Pre-load pressure
1. Pressure intentionally generated by a resistance in a system (e.g. in the outlet line of a system). 2. Pressure to which the oil in a tank is subjected if the suction of the pump requires this. To
Valve seals
Valve tappets which are guided outwards must be sealed off. This is generally done using nut rings or O-rings.
Pipe impedance
The column of fluid in pipes is elastic and affected by both weight and friction. These characteristics are described in terms of the pipe capacity , the pipe inductance and the flow resistance (effec
Monitoring time
Period of time, after which the outstanding instructions are reported (DIN 19 237).
Counter flow cooling
Normal cooling principle on water-cooled oil coolers. It states that the medium to be cooled flows in the cooling pipes in the cooler in the opposite direction to the cooling water.
Temperature drift
Unwanted change of a physical variable over time due to the influence of temperature.
