that has the task of adjusting the velocity in a system as a controlled variable as accurately as possible to a setpoint . For this purpose the actual velocity can be measured via a velocity transduce

proportional valve pilot-controlled plug-in valve that, unlike the 2-way plug-in valves permits, due to its 3rd port, the control of a single acting cylinder in the feed and reflux and if necessary, a

Systems designed to automatically perform monitoring tasks in the area of signal distribution . They are intended to analyse the signal paths to be monitored and compare them to the stored target path

All valves must be moved by external forces from a rest position to a working position . There is a series of ways of achieving this action that in DIN-ISO 1219 are divided into: manual actuation, mec

Method for making the functional - and often complex - relationships involved in the operation of hydraulic devices visible by means of schematics (circuit diagrams) in which the various processes are

A control that operates within the signal processing with digital signals and that primarily processes numerically represented signals (Figure D 28) . The signal processing is undertaken primarily wit

Sensor that changes its electrical resistance in proportion to the mechanical strain under load. Strain gauges are suitable for the electrical measurement of all mechanical variables that can produce

Computer with excess capacity, i.e. with redundant component configuration in which a replacement component becomes active as soon a part fails. Originally only used in large computers, today so-calle

Non-contact seal from the group of labyrinth gap seals on which fluid flowing outward is pumped back by a counter-rotating thread on the shaft. Here a pointed, triangular thread has proven effective (

Control in which the reference variable (n) is delivered by a time-dependent programmer . The programmer can be started by a trigger signal (DIN 19 226).
