Description
Viskositätsmeßvorrichtun für die Ermittlung von Auslaufzeiten.Viscosity measuring device for the determination of flow times.
Die vorliegende Erfindung betrifft eine Meßvorrichtung für Viskositätsmessungen nach dem Auslaufprinzip aus einem Meßbehälter mittels Auslaufdüse bestimmter Größe im Auslaufquerschnitt.The present invention relates to a measuring device for viscosity measurements according to the discharge principle from a measuring container by means of a discharge nozzle of a certain size in the outlet cross-section.
Derartige Meßmethoden ermitteln die Auslaufzeiten von flüssigen Medien, wie z.B. Lacken oder Ölen u.s.W.Such measuring methods determine the flow times of liquid media, such as paints or oils etc.
weitere Angaben sind der DIN 5.3 211 zu entnehmen.further information can be found in DIN 5.3 211.
Nachteil dieses Standes der Technik gegenüber der-Erfindung ist, daß die Ermittlung der Auslauf zeit durch die Bedienungsperson mittels Stoppuhr oder andere Zeitmesser abhängig ist von der Reaktionszeit der Bedienungsperson, welche den Versuch damit einleitet, indem sie die auf den gefUllten Meßbecher aufliegende z. B. Glasplatte von Hand wegzieht, wobei mit der anderen Hand mittels Stoppuhr der Beginn der Messung für die Auslaufzeit eingeschaltet wird und das Ende der Messung dort bestimmt wird, sobald der laufende Flüssigkeitsstrahl durch die aus dem Meßbecher auslaufende Flüssigkeit abreißt, was wiederum mittels Stoppuhrbetätigung zu ermitteln ist, Durch die äußerst umständliche Handhabung, daß immer eine Bedienungsperson an eine Meßstelle zeitlioh gebunden ist und dabei mit unterschiedlicher Reaktionszeit Xee.ungen durchfuhrt - gegenüber anderen Personen - ist der Nachteil dieies Standes der Technik gegenüber der Erfindung erheblich und wird durch die Erfindung beseitigt.The disadvantage of this prior art compared to the invention is that the determination of the run-out time by the operator using a stop watch or other timers depends on the operator's response time, which initiate the experiment by placing the measuring beaker on top of it z. B. pulls away glass plate by hand, with the other hand using a stopwatch the start of the measurement is switched on for the deceleration time and the end of the measurement there is determined as soon as the current jet of liquid through the out of the measuring cup Leaking liquid tears off, which in turn can be determined by actuating the stopwatch is, due to the extremely cumbersome handling, that there is always one operator is temporally bound to a measuring point and with different reaction times Performing Xee.ungen - compared to other people - is the disadvantage of this stand the Technology compared to the invention and is by the Invention eliminated.
Gegenstand der Erfindung ist eine automatische Ü-berwachungseinrichtung, an den an sich bekannten Auelaufbechern, wie sie z. B. durch die Norm DIN 53 21t zum Ausdruck gebracht sind.The subject of the invention is an automatic monitoring device, at the well-known Auelaufbechern, as they are z. B. by the standard DIN 53 21t are expressed.
Nachfolgend wird der Gegenstand der Brfindung anhand von Abb. 1 und Abb. 2 beachrieben: Der mit flüssigem Medium ( 3 ) gefüllte Auslau£-becher ( 2 ) ist durch eine z. B. Glasplatte ( 1 abgedeckt, was gleichzeitig verhindert, daß das flüssige Medium ( 3 ) aus der Auslaufdüse ( 4 austritt.The subject of the invention is described below with reference to Fig. 1 and Fig. 2: The outlet cup (2) filled with liquid medium (3) is through a z. B. glass plate (1 covered, which at the same time prevents the liquid medium (3) emerges from the outlet nozzle (4).
Die Überwachungseinrichtung ( 5 ), (66 ) und ( 7 ), bestehend aus z. B. einer Lichtschranke, ist so ausgerichtet, daß,sobald die Glasplatte ( 1 ) weggezogen wird,(Abb. 2) die Flüssigkeit ( 3 ) aus dem Auslaufbecher ( 2 ) austritt, wodurch der Flü@-sigkeitsstrahl ( 8 ) den Lichtstrahl ( 5 ) der Lichtschranke ( 5 ), ( 6 ) und ( 7 ) unterbricht, was schaltungstechnisch mittels Zeitmesser herangozogen wird, um für die Dauer der Unterbrechung des Lichtstrahls ( 6 ) Zeitmesser zu betreiben.The monitoring device (5), (66) and (7), consisting of z. B. a light barrier is aligned so that as soon as the glass plate (1) is pulled away, (Fig. 2) the liquid (3) emerges from the flow cup (2), whereby the liquid jet (8) the light beam (5) of the light barrier ( 5), (6) and (7) interrupt what is used in terms of circuitry by means of a timer to operate the timer for the duration of the interruption of the light beam (6).
