Vynález sa lýka membránového kapacitného; hlbkomeira pre meranie zmien výšky hladím kvapalín.The invention relates to membrane capacitance; hlbkomeira for measuring height changes by caressing liquids.
Doteraz používané metody merainia híbky kvapalín sú založené prevažne na principe plavákových híbkomerov s .mechanickým prevodom. Nevýhodou týchto prístrojov jej, že sú konštrukčné velmi zložité, ťažké v činnosti majú velkú poruchovost.The methods used to measure the depth of liquids used so far are based predominantly on the principle of float depth gauges with mechanical transmission. The disadvantage of these devices is that they are very complicated in design, difficult to operate and have a high failure rate.
Uvedené nedostatky odstraňuje .membránový kapacitný híbkomer kvapalín podlá vynálezu, ktorého podstata spočívá v tom, že v komoře je upevněná polymérová membrána stlačená predpatou pružinou, ktorá je opretá o nastavitelné pružinové sedlo s otvorom,, pričom na polymérovej membráně je nalepená pohyblivá doska kondenzátora s výhodom a pevná doska kondenzátora je upevněná v izolačnom krúžku s vývodem, přitom rúrka zíaliso varná v komoře je spojená s voinkajšou atmosférou hadicou.The above mentioned drawbacks are eliminated by the membrane capacitive liquid hygrometer according to the invention, which is characterized in that in the chamber is fixed a polymer membrane compressed by a bias spring, which is supported by an adjustable spring seat with an opening, with movable capacitor plate glued on the polymer membrane. and the fixed plate of the capacitor is fixed in the insulating ring with the outlet, while the heating tube in the chamber is connected to the external atmosphere by a hose.
Vynález membránového kapacitného híbkomera kvapalín umožňuje pomocou pólymérovej membrány a mernej pružiny s kapacitným snímačom a dialkový.m přenosem údajov okamžité a přesné meranie absolňtnej alebo relatívnej výšky vodných hladin. Přístroj má ipalé rozmary, je koiupiakitoý a v prevádzke spoíahlivý.The invention of the diaphragm capacitive liquid hygrometer enables an immediate and accurate measurement of the absolute or relative height of water levels by means of a polymeric diaphragm and a measuring spring with a capacitive sensor and remote data transmission. The device has unobtrusive whims, is co-operative and reliable in operation.
Membránový kapacitný híbkomer kvapalín je nakreslený v řeze na pripojenom obrázku.The diaphragm capacitive fluid meter is drawn in section on the attached figure.
Membránová komora 1, v ktorej je upevněná polymérová membrána 2, stláčaná pružinou 3 a upevněná je v pružinovom sedle 4 s otvorom 5. Polymérová membrána 2 má na praivej straně nalepenú pohyblivú dos49 ku 6 kondenzátora s vývodom 7, pričom pevná doska 8 kondenzátora je umiestnená v izolačnom krúžku 9 s vývodom 10 a fixovaná závitovým krúžkom 11. Rúrka 12 je zalisovaná do membránovej komory 1, na ktorej je nasunutá hadica 13 a zabezpečená ítesmlaicOu miatičou 14 s tesniacim krúžkom 15.The diaphragm chamber 1 in which the polymer membrane 2 is fixed, compressed by a spring 3 and is fixed in a spring seat 4 with an opening 5. The polymer membrane 2 has a movable plate 49 to the condenser pin 6 on the right side, the fixed capacitor plate 8 being located In the insulating ring 9 with the outlet 10 and fixed by the threaded ring 11. The tube 12 is pressed into the membrane chamber 1, on which the hose 13 is pushed and secured by a thimble 14 with the sealing ring 15.
Pri meraní sa l'avá strana polymérovej membrány 2 stýká s kvapalným prostředím. Přitom platí, že ak membrána 2 je v híbke h pod vodinou hladinou, potom tlak p působiaci na membránu 2 je p = χ. h, kde γ je mierná hmotnost kvapaliny. Sila P posobiaca na membránu sa vypočítá .podla vztahu P = Fe. p, kde Fe je efektívna plocha membrány 2. Přitom sila P je v rovnováhe s elastickou silou pružiny Pp a membrány PM podlá vztahu P = Pp + PM. Hodnoty Pp a PM sa volia tak, aby platilo Pp > PM.In the measurement, the left side of the polymer membrane 2 contacts the liquid medium. In this case, if the membrane 2 is at the depth h below the water level, then the pressure p acting on the membrane 2 is p = χ. h, where γ is the moderate mass of the liquid. The force P acting on the membrane is calculated according to the relation P = F e . p, where F e is the effective area of the membrane 2. The force P is in equilibrium with the elastic force of the spring P p and the membrane P M according to the relation P = P p + P M. The values P p and P M are chosen such that P p > P M.
Membrána 2 len utěsňuje vodný priestor od atmosferického prostredia, t. j. právej časti membránovej kantory 1, spojenej pomocou hadice 13 s priestorom nad vodniou hladinou. Týmto sposobom sa eliminuje vplyv zmien barometrického tlaku na výsledné meirané hodnoty. Změny priehybu membrány sú úměrné výške vodnej hladiny ΔΙι, ktoré sa elektricky prejavujú ako změny kapacity Δ0 kondenzátora ΔΗ » ΔΡ « « ΔΙι tvořeného pohyblivou doskou 6 kondenzátora a pevnou doskou 8 kondenzátora s vývodmi 7 a 10.The membrane 2 only seals the water space from the atmospheric environment, i. j. right part of the diaphragm canals 1 connected by a hose 13 to the space above the water level. This eliminates the effect of barometric pressure changes on the resulting measured values. Changes in diaphragm deflection are proportional to the water level ΔΙι, which are electrically manifested as changes in capacitance Δ0 of the capacitor ΔΗ »ΔΡ« «ΔΙ tvoř formed by the movable capacitor plate 6 and the fixed capacitor plate 8 with terminals 7 and 10.
Membránový kapacitný híbkomer kvapalín možno využiť pri meraní výšky vodných hladin v stojatých aj tekúcich vodách do híbky 30 m s peresinosťou + 2 cm.Membrane capacitive liquid level gauge can be used to measure water levels in stagnant and flowing waters up to 30 m depth with a peresinosti + 2 cm.
