Liquid nhanho yekuyera transmitter chiridzwa chinopa inoenderera yemvura kuyerwa kuyerwa. Inogona kushandiswa kuona mwero wemvura kana yakawanda yakasimba pane imwe nguva. Inogona kuyera chiyero chemvura yemedia semvura, viscous fluid nemafuta, kana midhiya yakaoma yakadai seyakawanda yakaoma uye hupfu.
Iyo liquid level yekuyera transmitter inogona kushandiswa mumamiriro akasiyana ekushanda senge midziyo, matangi uye kunyange nzizi, madziva nematsime. Aya ma transmitters anowanzo shandiswa mukubata zvinhu, chikafu nechinwiwa, simba, makemikari, uye maindasitiri ekuchenesa mvura. Zvino ngatitarisei akati wandei anowanzo shandiswa emvura level metres.
- Submersible level sensor
Zvichienderana nemusimboti wekuti iyo hydrostatic pressure inoenderana nekukwirira kwemvura, submersible level sensor inoshandisa piezoresistive mhedzisiro yesilicon yakapararira kana ceramic sensor kushandura iyo hydrostatic pressure kuita chiratidzo chemagetsi. Mushure mekubhadhara tembiricha uye mutsara kururamiswa, inoshandurwa kuita 4-20mADC yakajairwa ikozvino chiratidzo chekubuda. Iyo sensor chikamu che submersible hydrostatic pressure transmitter inogona kuiswa yakananga mumvura, uye iyo transmitter chikamu chinogona kugadziriswa neflange kana bracket, kuitira kuti zvive nyore kuisa nekushandisa.
Submersible level sensor inogadzirwa neyemhando yepamusoro yekuzviparadzanisa nesilicon sensitive element, iyo inogona kuiswa yakananga mugaba kana mvura kuti inyatso kuyera kureba kubva kumucheto we sensor kusvika pamusoro pemvura, uye kuburitsa mwero wemvura kuburikidza ne4 - 20mA ikozvino kana RS485 chiratidzo.
- Magnetic level sensor
Magnetic flap chimiro chakavakirwa pamusimboti we-by-pass pombi. Chiyero chemvura mupombi huru chinopindirana neicho chiri mumudziyo wemidziyo. Zvinoenderana nemutemo weArchimedes, iyo buoyancy inogadzirwa neiyo magineti inoyangarara mumvura uye chiyero chegiravhiti chinoyangarara padanho remvura. Kana mwero wemvura wemudziyo wakayerwa uchikwira nekudonha, iyo inotenderera inoyangarara mupombi huru yemamita echiyero chemvura inosimukawo ichidonha. Iyo inogara magineti simbi mune inoyangarara inotyaira iyo tsvuku uye chena koramu muchiratidzo kutendeuka 180 ° kuburikidza nemagineti yekubatanidza chikuva.
Kana mwero wemvura wakwira, chinoyangarara chinoshanduka kubva kuchena kuenda kutsvuku. Kana iyo nhanho yemvura yadonha, iyo inoyangarara inoshanduka kubva kutsvuku kuenda kune chena. Muganho muchena-mutsvuku ndiko kureba chaiko kweyero yemvura yepakati mumudziyo, kuitira kuti uone chiratidzo chemvura.
- Magnetostrictive liquid level sensor
Chimiro chemagnetostrictive fluid level sensor ine simbi isina tsvina chubhu (yekuyeresa tsvimbo), magnetostrictive waya (waveguide waya), inofambiswa inoyangarara (ine isingaperi magineti mukati), nezvimwewo. Kana iyo sensor ichishanda, chikamu chedunhu che sensor chinofadza kupuruzira ikozvino pawaveguide waya, uye iyo pulse ikozvino yakatenderedza iyo wave wave wave kugadzira waya waya.
Iyo inoyangarara inorongedzerwa kunze kwekuyeresa tsvimbo ye sensor, uye iyo inoyangarara inofamba ichikwira nekudzika pamwe nekuyeresa tsvimbo nekuchinja kweyero yemvura. Pane seti yekusingaperi magineti zvindori mukati mekuyangarara. Kana iyo pulsed yazvino magineti inosangana neiyo magineti mhete yemagineti inogadzirwa neinoyangarara, iyo magineti yakatenderedza iyo inoyangarara inoshanduka, kuitira kuti waveguide waya yakagadzirwa nemagnetostrictive material inogadzira torsional wave pulse panzvimbo yekuyangarara. Iyo pulse inofambiswa kumashure pamwe newaveguide waya nekumhanya kwakamisikidzwa uye inocherechedzwa nemaitiro ekuona. Nekuyera mutsauko wenguva pakati pekufambisa pulse ikozvino uye torsional wave, chinzvimbo chekuyangarara chinogona kutariswa nemazvo, ndiko kuti, chinzvimbo chemvura.
- Radio Frequency Admittance Material Level Sensor
Radio frequency admittance ndiyo nyowani nhanho yekudzora tekinoroji yakagadziridzwa kubva kune capacitive level control, inovimbika zvakanyanya, yakaringana uye inoshanda zvakanyanya. Iko kukwidziridzwa kwe capacitive level control tekinoroji.
Iyo inonzi radio frequency admittance inoreva kudzokororwa kwe impedance mumagetsi, iyo inoumbwa neresitive component, capacitive component uye inductive component. Radio frequency ndiyo redhiyo wave spectrum yeyakakwira-frequency fluid level mita, saka kubvumidzwa kweredhiyo kunogona kunzwisiswa sekuyeresa kubvuma neredhiyo yakakwirira-frequency wave.
Kana chiridzwa chichishanda, sensor yechiridzwa inoumba kukosha kwekugamuchira nemadziro uye yakayerwa yepakati. Kana iyo nhanho yezvinhu ichichinja, kukosha kwekubvuma kunochinja zvinoenderana. Iyo yedunhu yuniti inoshandura yakayerwa yekubvuma kukosha kuita yechinhu nhanho yekubuda kwechiratidzo kuti uone kuyerwa kweyero.
- Ultrasonic level mita
Ultrasonic level mita idhijitari level chiridzwa chinodzorwa ne microprocessor. Muchiyero, iyo pulse ultrasonic wave inotumirwa kunze ne sensor, uye ruzha rwekutinhira runogamuchirwa neiyo sensor mushure mekuratidzwa nechinhu chiri pamusoro, uye ichishandurwa kuita chiratidzo chemagetsi. Chinhambwe chiri pakati pe sensor uye chinhu chiri pasi pekuyedzwa chinoverengerwa nenguva iri pakati peiyo ruzha wave kutumira uye kugamuchira.
Izvo zvakanakira hazvisi zvemuchina chinofambiswa chikamu, kuvimbika kwakanyanya, nyore uye nyore kuisirwa, isiri-yekubata kuyerwa, uye haina kukanganiswa ne viscosity uye density yemvura.
Izvo zvisingabatsiri ndezvokuti kunyatsoita kwakaderera, uye muedzo uri nyore kuva nenzvimbo yebofu. Hazvibvumirwi kuyera kudzvinyirira mudziyo uye mhepo inopisa.
- Radar level mita
Iyo yekushanda modhi ye radar liquid level mita iri kufambisa inoratidza kugamuchira. Iyo antenna yeradar fluid level mita inoburitsa mafungu emagetsi, ayo anoratidzwa nepamusoro pechinhu chakayerwa obva agamuchirwa neantenna. Iyo nguva yemagetsi emagetsi mafungu kubva pakufambisa kuenda kugashira yakaenzana kune chinhambwe kusvika padanho remvura. Iyo radar liquid level mita inorekodha nguva yemafungu ekupuruzira, uye kumhanya kwekufambisa kwemafungu emagetsi kunoramba kuripo, ipapo chinhambwe kubva padanho remvura kuenda kune radar antenna inogona kuverengerwa, kuitira kuti uzive chiyero chemvura cheyero yemvura.
Mukushanda kwekushandisa, kune maviri modhi yeradar fluid level mita, anoti frequency modulation inoenderera mberi wave uye pulse wave. Iyo liquid level mita ine frequency modulated inoenderera mberi wave tekinoroji ine yakanyanya simba rekushandisa, ina waya system uye yakaoma yemagetsi dunhu. Iyo yemvura level mita ine radar pulse wave tekinoroji ine yakaderera simba rekushandisa, inogona kuvezwa neaviri-waya system ye24 VDC, iri nyore kuwana mukati chengetedzo, kurongeka kwepamusoro uye yakakura application renji.
- Inotungamirirwa wave radar level mita
Musimboti wekushanda weiyo inotungamirwa wave radar level transmitter yakafanana neiyo yeradar level gauge, asi inotumira microwave pulses kuburikidza ne sensor cable kana tsvimbo. Iyo siginecha inorova iyo yemvura pamusoro, yozodzokera kune sensor, uye yobva yasvika kune transmitter imba. Iwo emagetsi akabatanidzwa mune inotapurirana imba inotaridza iyo yemvura nhanho zvichienderana nenguva yainotora kuti chiratidzo chifambe pamwe ne sensor uye kudzoka zvakare. Aya marudzi ematanho ekutumira anoshandiswa mumaindasitiri ekushandisa munzvimbo dzese dze process tekinoroji.
