Position measurement by potentiometer
Position measurement by potentiometer is based on changes in the resistance in an electrical conductor as a function of its length ( Figure P 14 ). These days, position measurement by potentiometer is
Proximity switch
Switch which switches when an object is approached or left. Either inductive devices which can trigger at distances of up to 25 m are used for this purpose, or capacitive devices effective at distance
Micro-hydraulics
Widely used term, although not formally standardised or defined, for hydraulic components with nominal widths of up to around 3 mm and flow rates of up to around 20 l/min. Pressures of up to around 30
Multi-computer system
Digital computer system where a shared functional unit controls two or more central units, each of which has at least one processor. (EDIN 44 300, Part 5).
Power gain (amplification)
Relationship between the change in output power and the corresponding change in input (control) power.
Sensor for actual values
Signal element which specifies a signal for a specific process. (DIN 19 226)
Increment
Growth of a variable in identical individual stages Δ s .
Impulse metering lubricator
Device for the oil mist lubrication of compressed air whereby lubricating oil is allocated directly to the load based on the quantity and impulse sequence and independently of the air flow. This favou
Hydraulic signal technology
Signal range in which the signal input , signal linking and signal output use hydraulic components. Hydraulic signal technology is very expensive and only suitable for a few linking applications given
Hydraulic actuation
Actuation whereby switching movements are triggered by a flow of hydraulic oil and - depending on the design - the pressure alone or a combination of pressure and flow rate take care of actuation.
