Guhitamo uburyo bwo gupima ubushyuhe n'umuvuduko buhuriweho
2026-06-08
Mu gihe uhitamo ibikoresho by'ubushyuhe n'umuvuduko byinjijwemo, abakoresha benshi batanga amabwiriza bashingiye gusa ku rugero rw'umuvuduko. Kubera iyo mpamvu, nyuma yo gushyiraho, ibibazo nko gupima ubushyuhe nabi, kubangamira ibimenyetso bikomeye, cyangwa se gusubiramo sisitemu burundu bishobora kubaho—ahanini bitewe no kunanirwa kugenzura ibipimo bitatu by'ingenzi.
Jye Guhuza urugero rw'ubushyuhe: Ntukibande ku gitutu gusa mu gihe wirengagiza ubushyuhe.
Sensor ihujwe n'ubushyuhe ni igisubizo gihujwe gihuza igice cy'umuvuduko n'igice cyo kumenya ubushyuhe. Imiterere isanzwe igizwe n'igice cy'umuvuduko cya silikoni gihujwe n'ubudahangarwa bwa platine ya PT100, gifite urwego rw'umuvuduko rwa 0–60 MPa ariko ubusanzwe urwego rw'ubushyuhe rugarukira kuri -40°C kugeza 125°C.
Ikosa risanzwe ryo guhitamo:
Iyo ukoresha ubushyuhe bwa 150°C, guhitamo icyitegererezo gifite amanota ya 40 kugeza kuri 125°C bishobora gukumira gushya ako kanya kwa Sensor ya Pt100; icyakora, gushyuha cyane igihe kirekire bizatuma ubudahangarwa bw'amashanyarazi bugabanuka kandi bugatuma ubushishozi bugabanuka. Mu gihe cyo guhitamo, menya neza ko ubushyuhe nyabwo butagira ingano buguma muri 80% by'urugero rw'ibipimo bya sensor.
II Uburyo bwo kwishyura ubushyuhe: Kwishyura byikora ntabwo bikoreshwa ku bikoresho bidafite aho bihuriye
Uburyo bwo kwishyura ubushyuhe ku byuma bipima ubushyuhe n'umuvuduko buri mu bwoko bubiri: uburyo bwo kwishyura PT100 mu gihe nyacyo n'uburyo bwo kwishyura MEMS mu buryo bwa digitale. Uburyo bwa PT100 butanga uburyo bwo gupima ubushyuhe bwinshi (± 0.5°C) ariko busaba ko habaho ibimenyetso bibiri; uburyo bwo kwishyura bwa digitale bwa MEMS bufite uburyo bwo gushyira hamwe cyane ariko uburyo bwo kwishyura bugengwa na algorithme ikoreshwa.
Ibyifuzo byo guhitamo:
Ku bakoresha bafite ihindagurika rikomeye ry'ubushyuhe, nk'imikorere ya peteroli na sisitemu za hydraulic, igisubizo cya PT100 cyo kwishyura mu gihe nyacyo kirasabwa kubera uburyo bwo gupima ubushyuhe neza no gukosora umuvuduko neza; ku bakoresha bafite ubushyuhe buhamye, nka sisitemu za HVAC na sisitemu z'umwuka ufunze, MEMS-based digital compensation itanga uburyo bworohereza ikiguzi.
III Imiterere y'ikimenyetso cy'ibisohoka: Ntukivange umusaruro w'imiyoboro ibiri n'uburyo bwo gukwirakwiza imiyoboro imwe
Sensor integrated temperature-pressure sensor itanga ibimenyetso bitatu by'ibisohoka: 4–20 mA bidafite aho bihuriye n'ibipimo bibiri (ku gitutu n'ubushyuhe), 4–20 mA + RS485 hybrid output, cyangwa sharing time-sharing multiplexed output imwe.
Ibigomba kwitabwaho mu guhitamo:
Nubwo gukoresha uburyo bwo gusangira igihe hakoreshejwe umuyoboro umwe bisa nkaho bizigama insinga, amakuru y’umuvuduko n’ubushyuhe ntibiba bihuye neza mu gihe cyo guhinduranya insinga, bigatuma idakoreshwa mu kugenzura insinga zifunze. Umusaruro wa 4–20 mA ufite imiyoboro ibiri utanga ituze ryo hejuru, insinga zoroshye, kandi urwanya cyane ingaruka mbi, bigatuma iba nziza cyane mu nganda nyinshi.
Ikindi cyibutswa: Irinde ingorane zikunze kugaragara zo gushyiramo
Ubushyuhe buhuriweho-Sensor y'umuvuduko ipima ubushyuhe n'umuvuduko w'amazi ari mu muyoboro, aho ishyirwa rigira ingaruka ku buryo butaziguye ku gupima. Ni byiza kuyishyira ku bice by'imiyoboro igororotse ifite uburebure bwa metero eshanu mbere na nyuma; irinde kuyishyira hafi y'inkokora cyangwa valve; mu gihe upima amazi, sensor igomba gushyirwa hasi cyangwa mu buryo butambitse kugira ngo hirindwe ko ibibyimba byiyongera.
Mu gihe uhitamo ubushyuhe buhuriweho na Sensor y'umuvuduko, ibipimo bitatu by'ingenzi bigomba kuzuzwa: imipaka y'ubushyuhe yagenwe, uburyo bukwiye bwo kwishyura kugira ngo hamenyekane ko ari ukuri, no kohereza ibimenyetso bisohoka mu buryo buhamye. Niba ugorwa no guhitamo, nyamuneka hamagara itsinda rya Weilian Fengran rishinzwe ikoranabuhanga ryo kumenya—dutanga ubuyobozi bwuzuye bwo guhitamo ubushyuhe buhuriweho-Sensor y'umuvudukoserivisi zo gupima icyitegererezo.
