Li-sensor tsa ceramic tse sebetsang hantle, tse theko e tlase e tla ba tataiso ea nts'etsopele ea Sensor sa Khatellos.

Ceramic Sts'ebetso ea tlhahiso ea ensor

tlhamo

Ha u ntse u etsa li-sensor tsa ceramic, ntho ea pele eo u lokelang ho e etsa ke ho sebetsana le lisebelisoa tsa ceramic:

① Shebella phofo ea ceramic ho netefatsa likaroloana tse tšoanang.

②E sebedise ka sebopeho le boholo bo hlokahalang. Mekhoa e atileng haholo ke ho bopa, ho bopa ka ente, ho etsa die casting le extrusion.

③Ho omisa le ho omisa. Nako le mocheso li hloka ho khethoa ho latela litšobotsi le sebōpeho sa thepa ea ceramic.

④Ho hloekisa ho tlosa litšila le litšila holim'a metsi.

⑤Kalafo ea Passivation. Sebelisa motsoako o itseng oa oxidizing acid kapa alkali ho etsa hore tšepe e holim'a sensor e hlahise karabelo ea oxidation ka oksijene ho etsa filimi ea oxide.

⑥Ka mor'a hore thepa ea ceramic e sebetsanoe, mokhoa oa bohlokoa oa ho etsa li-sensor tsa ceramic ke khatiso e teteaneng ea filimi, e hatisang lesela la elektrode, lesela la ho hanyetsa le lesela la encapsulation ka ho latellana.

Ho sebetsa Principle:

Khatello e bohareng e sebetsa ka kotloloho ho diaphragm ea ceramic, e etsang hore diaphragm ea ho lekanya e fetohe. Khatello e tloaelehileng e etsa hore diaphragm e fetohe ka 0.025mm, 'me khatello e feteletseng e etsa hore diaphragm e fetohe ka 0.1mm. Ka nako ena, diaphragm ea ho lekanya e khomaretsoe ka har'a bracket ea ceramic ho qoba tšenyo. The capacitance e hlahisoang ke ho falla ha diaphragm e fumanoa, e matlafatsoa le ho fetoloa hore e be pontšo e tloaelehileng e hlahisoang ke likarolo tsa elektronike tse amanang ka ho toba le eona.

Melemo ea li-sensor tsa ceramic

• Bokhoni bo matla ba khatello e phahameng ea khatello

Mekhahlelo ea ho lekanya ea lisebelisoa tsa ceramic e itšetlehile ka botenya ba diaphragm ea ceramic, kahoo ha sensor e kopana le boemo ba mojaro bo fetang mojaro oa eona, sehlahisoa se seholo se ke ke sa senyeha ka ho sa feleng ho latela tšehetso ea motheo ea diaphragm ka boeona.

• Ha ho phoso ea zero e bakoang ke phello ea "memori".

Ka kakaretso, li-diaphragm tsa tšepe hangata li na le seo ho thoeng ke "memory" (phello ea mohopolo: e bua ka ho otlolla le ho senyeha ha lintho nako le nako ha khatello e sebelisoa, haholo-holo khatello e phahameng, 'me e ke ke ea khutlisetsoa boemong ba eona ba pele ha khatello e nyamela). Ka hona, li-sensor tsa diaphragm tsa tšepe li na le liphoso tsa boemo ba zero ho tlhahiso ea transmitter.

Ka lebaka la litšoaneleho tsa sebopeho sa eona le micro-motion, li-sensor tsa ceramic li ka khutlela sebakeng sa tsona sa pele kamora ho ba tlas'a khatello ka har'a sebaka se lekaneng kapa esita le ho feta sebaka se lekaneng, se ntlafatsang ho pheta-pheta ha tlhahiso ea transmitter.

• Ha e angoe ke mocheso

Li-sensor tsa metal diaphragm li angoa habonolo ke ho atolosoa ha mocheso le ho honyela, ho amang ho pheta-pheta ha tsona. Lisebelisoa tsa ceramic li batla li sa amehe ka ho atolosoa ha mocheso le ho fokotseha. Ha ho na ho tlatsoa ha oli ha ho etsoa li-gauge tsa khatello le li-sensor tse felletseng, ka hona ha ho na phoso e bakoang ke ho atolosoa ha mocheso le ho fokotseha ha mokelikeli oa ho tlatsa. Tšobotsi ena ea li-sensor tsa ceramic e loketse haholo bakeng sa ho fumana litekanyo tse ntle tsa ho pheta-pheta maemong ao liphetoho tsa mocheso li hlakileng haholo.

Tšebeliso ea li-sensor tsa ceramic

Li-sensor tsa Ceramic li 'nile tsa sebelisoa haholo likarolong tse ngata ka lebaka la melemo ea tsona e ikhethang ea ts'ebetso, ho kenyelletsa le lisebelisoa tsa elektronike tsa likoloi, sefofane, ho shebella tikoloho, ho hlahlojoa ke bongaka, joalo-joalo Ka tsoelo-pele e potlakileng ea Inthanete ea Lintho, Inthanete ea selefouno, matla a macha le lisebelisoa tse phahameng tsa tlhahiso ea lisebelisoa, kholo ea boholo ba 'maraka oa bona e tsamaisitse tlhokahalo ea lisebelisoa tsa ceramic. Ka 2023, tekanyo ea li-sensor tsa ceramic naheng ea heso e tla fihla ho li-yuan tse limilione tse likete tse 21.772; lebaleng la likoloi, sekhahla se tla fihla ho li-yuan tse limilione tse likete tse 5.544, ka sekhahla sa kholo ea 16% ho tloha 2017; mafapheng a mang, sekhahla se tla fihla ho li-yuan tse limilione tse likete tse 16.228, ka sekhahla sa kholo ea 10.4% ho tloha 2017.

Lebaleng la likoloi, li-sensor tsa ceramic li sebelisoa haholo ka likarolo tse hlano.

(i)Ho lemoha mocheso oa koloi. Thermistor e mpe ea mocheso (NTC) - li-sensor tsa mocheso li atisa ho sebelisoa ho lemoha metsi a pholileng, moea o kenang le mocheso oa oli ea enjene. Positive temperature coefficient (PTC) thermistor - li-sensor tsa mocheso hangata li sebelisoa e le li-sensor tsa boemo ba mokelikeli oa koloi kapa mocheso o tlase o qalang ho futhumatsa lintho.

(ii) Ho lemoha mosi oa koloi. Ho sebelisoa lisebelisuoa tsa ceramic tse sa utloeng bohloko ka khase ea electrolyte, li-sensor tsa oksijene bakeng sa ho lekola mosi oa koloi li ntlafatsoa ho lekanya khatello ea oksijene mosi o tsoang ho bona tekanyo ea mafura a moea le enjene. Ntle le ho boloka mafura, e ka boela ea fokotsa ho ntšoa ha likhase tse kotsi tse kang CO le NO2.

(iii) Ho lemoha boemo ba ho sebetsa ba silindara. Piezoelectric ceramic knock sensor e entsoe ka piezoelectric ceramic vibrator, letlapa la tšepe, gasket ea ho tiisa, khetla ea tšepe, joalo-joalo Li-ceramics tsa piezoelectric tse thehiloeng ho phello ea piezoresistive li ka shebella boemo ba ho sebetsa ba silinda.

(iv) Ho tataisa ho khanna ho bolokehileng ha koloi. Li-sensor tsa Ultrasonic tse thehiloeng ho phello ea piezoresistive li sebelisoa e le lisebelisoa tsa alamo tse thibelang ho thulana ha likoloi, tse tsejoang hape e le li-radar tsa ultrasonic reversing kapa reversing Sonar systems. Li-sensor tsa Ceramic acceleration li ka sebelisoa lits'ebetsong tsa mekotla ea moea ea koloi.

(v) Ho lemoha mongobo oa koloi. Li-sensor tsa mongobo li loketse ho lemoha serame le condensation ea lifensetere tsa koloi le mongobo oa moea karolong e kenang ea enjene ea carburetor.

E le mohloli oa tlhahisoleseling oa litsamaiso tsa taolo ea elektroniki tsa likoloi, li-sensor tsa likoloi ke likarolo tsa bohlokoa tsa sistimi ea taolo ea elektroniki ea likoloi le e 'ngoe ea litaba tsa mantlha tsa lipatlisiso lefapheng la mahlale a elektroniki a likoloi. Ha tekanyo ea lisebelisoa tsa elektronike le li-automation e phahame, ho itšetleha haholo ka li-sensor. Khamphani ea rona e ka u fa mefuta e fapaneng ea boleng bo holimo, ts'ebetso e phahameng, le lisebelisoa tse ngataCablelihlahisoa ho kenyelletsa le li-sensor tsa ceramic, hape e ka fana ka lihlahisoa tse ikhethileng ha li kopa. Ka kopo ikutloe u lokolohile ho iteanye le ronahaeba u e hloka!

Kea leboha ha u ntse u bala, ka kopo etela sebaka sa rona sa marang-rang ho fumana lintlha tse ling!
