Doteraz známy zvonový tlakoměr,pracujúci pri konštatnej zvislej polohe zvona je riešený tak,že merací zvon je zavesený na vahadle váhy a takto je meraná sila pčsobiaca na zvon účinkom meraného tlaku.Takto riešený zvonový tlakoměr nemá uzavretý priestor nad zvonnom,pretože váha nie je opatřená těsnými krytom a takýto kryt by bol ťažko riešitel’ný,nie je možné zvonovým tlakomerom merať diferenčně tlaky.fialej citlivosť váhy následkom čiastočného ponorenia zvona do tesniacej kvapaliny sa znižuje a tým sa nezabezpecuje dostatočne konštantná zvislá poloha zvona,čím sa znižuje přesnost merania tlaku.The known bell pressure gauge operating at a constant vertical position of the bell is designed so that the measuring bell is suspended on the balance rocker and thus the measured force acting on the bell by the measured pressure is measured.This solved bell pressure gauge has no closed space above the bell, It is not possible to measure differential pressures with a bell manometer. The balance's sensitivity due to partial immersion of the bell in the sealing liquid is reduced and thus the sufficiently vertical vertical position of the bell is not ensured, thereby reducing the accuracy of the pressure measurement.

Vyššie uvedené nedostatky odstraňuje diferenčný zvonový tlakoměr,pozostáva júci z meracieho zvona a telesa s uzavretým priestorom nad zvonom podl’a vy nálezu, ktorého podstata spočívá v tom, že merací zvon je zavesený na pružině a táto je zavesená z vnútra na uzatváracej časti vlnovca,ktorý je druhou stranou upevněný na telese táakomera.Uzatváracia posuvná časť vlnovca je upevněná otočné,pomocou gul’ového závěsu,na vřetene mikrometrickej skrutky .Mikrometrická skrutka je upevněná pomocou držiaka na telese tlakoměre.The above-mentioned drawbacks are remedied by a differential bell-type pressure gauge consisting of a measuring bell and a body with a closed space above the bell according to the invention, which consists in that the measuring bell is suspended from a spring and suspended from the inside on the closing part of the bellows. The closing sliding part of the bellows is mounted rotatably, by means of a ball hinge, on the spindle of the micrometer screw. The micrometer screw is mounted by means of a holder on the body of the pressure gauge.
Meranie vyvodenej sily na zvon účinkom meraného tlaku pomocou pružiny a mikrometrickej skrutky umožnilo zmenšenie rozmerov tlakomera,uzavretie priestoru nad zvonom a tým aj meranie diferenčných tlakov.Použitie elektrického kapacitného snímača zvislej polohy zvona umožnilo presnejšie nastavenie tejto polohy a tým aj presnejšie meranie tlaku.Zmenšenie rozmerov prinieslo materiálové úspory a tiež úsporu samotnéj váhy.Measuring the exerted force on the bell by means of the measured pressure by means of a spring and a micrometer screw allowed to reduce the dimensions of the pressure gauge, to close the space above the bell and thus to measure the differential pressures. brought material savings as well as weight savings.
Tlakoměr podl’a obrazu pozostáva z meracieho zvona 1 a telesa 4, v ktorom je vytvořený priestor pře tesniacu kvapalinu 8.Zvon 1. je ponořený spodnou časťou do tesniacej kvapaliny S.Merací zvon 1 je zavesený na pružině 2 a táto je zavesená zospodu na uzatváracej posuvné j časti vlnovca 3·Tento je^řojou dolnou časťou upevněný na telese 4. Posuvná uzatvéracia časť vlnovca je zavesená otočné pomocou gumového závěsu vřetena £ mikrometrickej skrutky 6.Táto je upevněná na telese 4 pomocou držiaka 9.V uzavretom priestore nad zvonom 1 je umiest nený pevný elektrický kapacítný snímač 7,upevněný na hornej časti telesa 4.The pressure gauge according to the figure consists of a measuring bell 1 and a body 4, in which space is formed over the sealing liquid 8. The bell 1 is immersed in the sealing liquid S by the bottom. The measuring bell 1 is suspended from the spring 2 and The sliding closing part of the bellows is hinged rotatably by means of a rubber hinge of the spindle 6 of the micrometer screw 6. This is fastened to the body 4 by means of the holder 9.In a closed space above the bell 1 a fixed electrical capacitance sensor 7 is mounted on the upper part of the body 4.
Meranie tlaku diferenčným zvonovým tlakomerom sa uskutočňuje následovně:Před meraním sa vzájomne prepoja přívody meraných tlakov horný přívod 10 a dolný přívod 11,čím nastane vyrovnanie tlakov.Za tohoto stavu,pomocou mikrometrickej skrutky 6 a elektrického kapacitného snímača 7 sa nastaví zvon 1 do danej pracovnej polohy.DÍžkovýThe pressure measurement with the differential bell-type pressure gauge is carried out as follows: Prior to the measurement, the upper pressure inlet 10 and the lower pressure inlet 11 are connected to each other for pressure equalization.At this stage, by means of micrometer screw 6 and electrical capacitive sensor 7 polohy.DÍžkový
224 570 údaj mikrometrickej skrutky (, odpovedá nulovému rozdielu tlakov.Po přivedení meraných tlakov,ktorých rozdiel sa má merať,pričom vyšší tlak sa vždy privádza do horného přívodu 10,sa znovu nastaví pomocou mikrometrickej skrutky £ a elektrického kapacitného snímača 7 zvon 1 do danej pracovnej polohy .Rozdiel dížkových údajov mikrometrickej skrutky 6 po nastavení zvona 1 do danej pracovnej polohy po přivedení meraných tlftkov a a při nulovom tlakovom rozdiele je úměr ný meranému tlakovému rozdielu a z něho sa tento stanoví.224 570 the reading of the micrometer screw (, corresponds to zero differential pressure. After applying the measured pressures whose difference is to be measured, the higher pressure being always supplied to the upper inlet 10, the micrometer screw pomocou and the electrical capacitive sensor 7 bell 1 are reset. The difference in the length data of the micrometer screw 6 after setting the bell 1 to the given operating position after the measurement of the measured thicknesses is applied and at zero pressure difference is proportional to the measured pressure difference and from this it is determined.
