Zahlula yepresha: umgaqo kweentlobo amanyathelo kunye iintlobo. Indlela ukukhetha manometer umahluko

Uxinzelelo kumajelo eendaba sukube kwaye ulwelo phakathi parameters ibalulekileyo, umlinganiselo efunekayo ulondolozo zonxibelelwano kunye neenkqubo processing. izinto Operable ziquka okucoca ezahlukeneyo, iinkqubo imibhobho, izixhobo ze moya kunye umoya. Ukusebenzisa umahluko yepresha, umsebenzisi utyhila nje iimpawu xi ngoku, kodwa ke unako ukufaka umahluko phakathi komsebenzi olutshintshayo. Ulwazi ezi data ibhexesha esweni kwenkqubo kwaye yandisa ukuthembeka ukusebenza. Ukongeza, eqhutywa umahluko esetyenziselwa umlinganiselo flow fluid, igesi okanye umoya.

isimiso ukusebenza

Kuninzi iinkcazelo usebenzsa zobuchwepheshe kunye nokubalwa data ngokusekelwe kwiinkqubo deformation beeyunithi ezithile zemilinganiselo, ezifana imfutho. Esi element ikhonza salathisi ukwahluka qwa uxinzelelo. Kwaye iyunithi umahluko uba yokusebenza xi transducer - umsebenzisi ifumana ulwazi ekwimo isalathisi se itolo kwisiphelo sixhobo. Ukongeza, iinkcukacha zinganikezelwa e Pascals, eziquka yonke lokulinganisa kuluhlu. Le ndlela ukubonisa ulwazi, umzekelo, inika Testo umahluko manometer 510 ukuba inkqubo womlinganiselo ishenxisa imfuneko uyibambe esandleni sakhe, ngenxa yokuba Ezomva divayisi oomazibuthe ezikhethekileyo.

Iingcinga mechanical njengoko isalathisi engundoqo indawo ye utolo kulawulwa yinkqubo lever. movement isalathisi kwenzeka de ukuhla mzuzu kwinkqubo akuyi kuyeka kuchaphazela namandla ethile. Umzekelo classic yale nkqubo ibonisa umahluko manometer DM 3538M uthotho olunika inguqu Delta naqondo (uxinzelelo umahluko) kwaye inikeza ngenxa umqhubi njengophawu emanyeneyo.

ngezigaba

Ngenxa ukuntsonkotha inkqubo womlinganiselo yengcinezelo, iimpawu eendaba zokusebenza kunye nokutshintshwa ngakumbi, kukho ezahlukeneyo eziliqela xi umehluko ukusebenza kwiimeko ezahlukeneyo. Hi ndlela leyi, uxinzelelo umahluko, nto leyo umgaqo yokusebenza eyilwe luqinisekiswa kakhulu isixhobo yakho sijoliswe kwi amathuba isicelo kwindawo ethile - kungoko oku kwenziwa kunye yokuhlela. Ngoko ke, abenzi kufuneka models ezilandelayo:

• soxinzelelo lwegazi ulwelo umahluko Group, equka umbhojana, intsimbi, ityhubhu kunye umsesane nokulungalungiswa. Bona inkqubo womlinganiselo ithatha indawo ngokusekelwe column ulwelo yokusebenza.
• soxinzelelo lwegazi Digital lock. Ingqalelo kakhulu esebenza; kuba zinika ukukwazi ukulinganisa kuphela iimpawu idrophu koxinzelelo, kodwa isantya lokusetyenziswa kwemali umoya, izalathi si zokunikwa ukufuma kunye obushushu. A ummeli abaziwayo beli qela yi xi umahluko imagers gauge evela Testo, nto leyo nayo kusetyenziswa kwiinkqubo ze esweni kokusingqongileyo, nomoya kunye nezifundo zokusingqongileyo.
• izixhobo mechanical Category. Oku imfutho kunye uguqulelo uvalo enika umlinganiselo ngokubeka esweni iimpawu yengcinezelo element ezibuthathaka.

-Pipe Two imodeli

Ezi zixhobo zisetyenziswa ukulinganisa izalathi uxinzelelo nokumisela therebetween umahluko. Esi sixhobo ne kwinqanaba ebonakalayo, ongowona kwifomu emise oku kuka-U. Xa isakhiwo enjalo umahluko ufakelo yepresha kweetyhubhu ezimbini oqhagamshelwano phakathi nkqo leyo njo kwisiseko ngomthi okanye umgubo wentsimbi. It is a licandelo mandatory lesixhobo kunye nembasa yesikali. Ukulungiselela ityhubhu womlinganiselo ezaliswe zokusebenza eziphakathi.

Ngaphezu koko, enye imibhobho, etyisa uxinzelelo elilinganisiweyo. Ngaxeshanye, umbhobho yesibini enxibelelana emoyeni. Ngexesha umlinganiselo ogudle, zombini ityhubhu xi kulinganiswa kuvavanywa. A tube-ezimbini uxinzelelo umahluko gauge iziseko ulwelo isetyenziselwa ukulinganisa izalathi lwepolitiki, uxinzelelo iigesi non-bako neemeko zomoya.

model monotube

Monotube soxinzelelo lwegazi umahluko zidla kusetyenziswa, ukuba kuyimfuneko ukufumana ukuchana japan eliphezulu. Xa izixhobo ezinjalo, usebenza ngesitya, aye kwi uxinzelelo kunye ingumlingani inkulu. Kuphela ithumbu zigxunyekwe nembasa kunye isikali ebonisa iinkcukacha umahluko, kwaye inxibelelane bume komoya. Ngexesha xi drop womlinganiselo ngayo esinxibelelana xi lincinci. Ukusebenza medium igalelwe igeyiji xi mahluko ukuya kwinqanaba de zero sifikelelwe.

Phantsi koxinzelelo inxalenye ethile kulwelo lungena ngokukhululekileyo ityhubhu ukusuka isitya. Ekubeni umthamo kolwelo zomsebenzi ukuba liyagungqa kwi ityhubhu lokulinganisa, ekwafanekisa ivolyum ingakhutshwa kuphela isitya, a manometer olunye-ityhubhu iquka ilinganisa ubude bomhlathi engamanzi. Ngamanye amazwi, imadlana impazamo womlinganiselo. Nangona kunjalo, yaye olu hlobo izixhobo azikho ukhululekile kuneengxaki.

Ukutenxa amaxabiso kangangoko inokuba ngenxa yokwanda thermal ze udweliso lweenkqubo isixhobo lokulinganisa, yokusebenza ingxinano eliphakathi kunye nezinye iimpazamo, Noko ke, leyo, ukuba uphawu zonke iintlobo itshintshela uxinzelelo. Hi xikombiso, xi umahluko digital elilungiswe ngenxa parameters of lexinene lobushushu okuza une umqobo ethile impazamo.

kovalo yepresha umahluko

Le uhlobo olunganeno engundoqo ngoomatshini uxinzelelo umahluko, nto leyo nayo yahlulwe izixhobo kunye sisinyithi nezinto umlinganiselo nonmetallic. Kwizixhobo nge izibalo yesinyithi uvalo flat zisekelwe iimpawu nitrogen aphambuke kwicandelo lokulinganisa. Common kwaye zahlula-noxinzelelo, apho inwebu isebenza isahlulelo emagumbini ngokwahlukana. Ngexesha deformation yomkhosi indlela ekwenzeka ngayo ngumthombo zezindlu helical aso i element lokulinganisa. Ekubeni kukho uthelekiso amaxabiso uxinzelelo ezimbini ezahlukeneyo.

Kwakhona ezinye ukulungisa izixhobo inwebu banikwa nokhuseleko ngandlela-nye-nokubhenca - Lo msebenzi kuyilo ivumela ukuba kusetyenziswa ekulinganiseni yokusebenza ye overpressure. Nangona elektroniki esebenzayo ekuphunyezweni ishishini metrological xa iyonke, iigeji uvalo kuhlala zifunwa kwaye sele kwezinye iindawo. Umzekelo, abaxhakaxhaka umahluko manometer DMC 01M uhlobo digital, nangona ergonomics kunye nokuchaneka ophezulu, ukulinganiselwa ekusetyenzisweni phantsi kweemeko apho inwebu kungenziwa eziqhutshwa izixhobo.

imfutho version

Xa imifuziselo ezinjalo, element yokulinganisa ibhokisi incence evela otyhidiweyo, gcwalisa kwentwasahlobo helical. isixhobo moya yahlulwe imfutho ezimbini. Impembelelo enkulu yengcinezelo iwela ikhamera ngaphandle imfutho, kwaye incinane - em- engaphakathi. Ngenxa imikhosi kunye noxinzelelo ezahlukeneyo isivamvo into gqitha ngokungqinelana ixabiso ngokomlinganiselo inani elifunekayo. Le usebenzsa odidi uxinzelelo umahluko, ebonisa iziphumo ngokwemilinganiso yi itolo kwisiphelo dial. Kodwa kukho amanye amalungu ale ntsapho.

Okunye version mechanical

thunzi azixhaphakanga, intsimbi edada kunye isixhobo umahluko xi yokulinganisa. Nangona kukho besshkalnye echanileyo kwaye recording model, kwakunye nezixhobo kunye nezixhobo zombane zoqhagamshelwano. ukudlulisela Data kubo kwakhona ngaphandle ukude uqhagamshelo wombane okanye ngomoya. Ukuze ubone indlela yokusebenza nenkcitho ngokusekelwe variables umahluko kwakhona ukuvelisa izixhobo ngoomatshini kunye ukushwankathela yaye bahlanganisa nezongezelelo.

soxinzelelo lwegazi umehluko Digital

Devices yalo hlobo ngaphandle imisebenzi esisiseko yokulinganisa umahluko xi nga imisele iindawo yokusebenza olutshintshayo. izixhobo ezinjalo designated iimpawu DMC-01M. Digital zahlula yepresha, ingakumbi, kusetyenziswa ukulawula anoomatshini bokungenisa, izibonelelo mveliso, likuvumela ukuba ukubala parameters ukusebenzisa igesi, kuthathelwa ingqalelo uhlengahlengiso ubushushu, kwakunye ugcine irekhodi yeendleko umyinge zithuba kulinganiswa. Izixhobo inikwa kunye isilawuli ukuba igcina ngokuzenzekelayo iirekhodi imilinganiselo kunye nokwanda kolwazi flue gas. Yonke ingcaciso efunyenweyo inkqubela window ebonisiweyo.

Izindululo ngokukhetha i

Intengiselwano zalathisi xi ezifuna isixhobo oluthembekileyo, kwemiqathango ahambelanayo yokusebenza eliphezulu. Kule nkalo, kubalulekile ukuba isigqibo uluhlu lwemisebenzi eya kwenziwa yi kwisixhobo. Hi xikombiso, xi umahluko Testo 510 uyakwazi ukunika Ufundo oluchanileyo imbuyekezo lobushushu kwaye ukubonelela ngedatha kwi kwidispleyi lwedijithali. Kwezinye iimeko, umfuziselo kweesiginali, ngoko ke kufuneka uthathe ingqalelo ukufumaneka olu khetho.

Kuba advance ubuninzi data esebenzayo kuyimfuneko ukuthelekisa iimpawu kwefowuni kunye amathuba abasebenza kwindawo ethile yokusebenza. Ayizizo zonke izixhobo ungasetyenziswa ioksijini, ammonia kunye freon umoya. Noko ke, ukuze babe ukuchana eliphantsi.
