Abstract:
The rpm-measurement device proposed works with a stationary wire pulse sensor (5) which is controlled by the magnetic fields of a multiplicity of radially aligned rotating magnets (4). The speed of rotation of a component (3a) located on a shaft (3) is determined by virtue of the fact that each pulse in the wire pulse sensor (5) is triggered by two opposite poles (N, S) located a certain longitudinal distance apart. The measurement device proposed provides reliable measurement values independently of the rpm, particularly in the lower rpm range.
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Messen und/oder Überwachen des Durchflusses eines Fluids durch einen Kanal mit einem in den Kanal hineinreichenden auslenkbaren Teil, dessen Auslenkung den Durchfluss anzeigt, wobei das auslenkbare Teil im nicht ausgelenkten Zustand den Kanal völlig verschließt und das Ventilstellglied eines Rückschlagventils bildet.
Abstract:
The invention relates to a device for measuring and/or monitoring the flow of a fluid through a channel, comprising a deflectable part extending into the channel, wherein the deflection thereof indicates the flow, wherein the deflectable part completely closes the channel in the non-deflected state and forms the valve actuator of a check valve.
Abstract:
Die Erfindung betrifft eine Kreiselpumpe mit einem Saug- und einem Druckstutzen (3, 5) und einem den Volumenstrom messenden Durchflusssensor (11), wobei der Durchflusssensor in der Wand des Saug- (7) oder Druckstutzens lösbar befestigt ist und mit einem das Fluid- insbesondere den Flüssigkeitsstrom sensierenden Teil (12) in den Stutzenkanal hineinreicht.
Abstract:
The gas-pressure controller proposed is characterized in that an obturator disc (9) is connected to a valve spindle (7) on the input side so that it can move longitudinally. The obturator disc (9) is pressed by an elastic component in the "open" direction and opens to give a flow channel (3) when the output pressure is above a minimum value. The obturator disc (9) closes off the flow channel (3) when the output pressure drops below the minimum value, lleaving a very small flow aperture (12). The gas-pressure controller proposed is intended for use in medium-pressure applications. The controller starts up again automatically after a gas failure.
