1. Ha u kenya mokokotlo oa sensor ea ceramic, ke habohlokoa ho tsepamisa mohopolo ho kenya ho emisa.Sebopeho se lokela ho kenyelletsa lesale la khatello e tsitsitseng ho fokotsa boemo ba motsoako oa sensor le ho netefatsa hore esita le kabo ea khatello ea kelello.Sena se thusa ho qoba mefuta e fapaneng ea khatello ea maikutlo e ka bakoang ke basebetsi ba fapaneng.
2. Pele ho welding, etsa tlhahlobo ea pono ea pad pad.Haeba oxidation e le teng holim'a pad (e etsa hore e be lefifi), hloekisa lesela ka raba pele u tjheseletsa.Ho hloleha ho etsa joalo ho ka baka tlhahiso e mpe ea lets'oao.
3. Ha u cheseletsa lithapo tse etellang pele, sebelisa tafole ea ho futhumatsa e nang le taolo ea mocheso e behiloeng ka likhato tse 140-150.Tšepe ea solder e lokela ho laoloa ka likhato tse ka bang 400.Flux e thehiloeng metsing, e sa hlatsoeng e ka sebelisoa bakeng sa nale ea ho cheselletsa, ha pente e hloekileng ea flux e khothaletsoa bakeng sa terata ea welding.Linonyello tsa solder li lokela ho ba tse boreleli le tse se nang li-burrs.Fokotsa nako ea ho kopana lipakeng tsa tšepe ea soldering le pad, 'me u qobe ho siea tšepe ea solder holim'a sensor pad bakeng sa metsotsoana e fetang 30.
4. Ka mor'a ho tjheseletsa, ha ho hlokahala, hloekisa phallo e setseng pakeng tsa lintlha tsa ho tjheseletsa ho sebelisa borashe e nyenyane ka motsoako oa likarolo tse 0,3 tse feletseng tsa ethanol le likarolo tse 0,7 tsa boto ea potoloho.Mohato ona o thusa ho thibela phokotso e setseng ho tloha ho hlahisa capacitance ea parasitic ka lebaka la mongobo, e ka amang ho nepahala ha lets'oao la tlhahiso.
5. Etsa tlhahiso ea pontšo ea tlhahiso ho sensor e nang le welded, ho netefatsa hore ho na le letšoao le tsitsitseng la tlhahiso.Haeba ho tlola data ho etsahala, sensor e tlameha ho ts'oaroa hape ebe e kopanngoa hape kamora ho fumana.
6. Pele o lekanya sensor post-assembly, ke habohlokoa ho beha likarolo tse bokelletsoeng khatellong ea maikutlo e le ho leka-lekanya khatello ea kopano pele ho tekanyo ea pontšo.Ka tloaelo, libaesekele tse phahameng le tse tlase tsa mocheso li ka sebelisoa ho potlakisa tekano ea khatello ea likarolo ka mor'a ts'ebetso ea ho atolosa le ho fokotseha.Sena se ka finyelloa ka ho beha likarolo ho mocheso oa -20 ℃ ho 80-100 ℃ kapa mocheso oa kamore ho 80-100 ℃.Nako ea ho kenya mocheso libakeng tse phahameng le tse tlase tsa mocheso e lokela ho ba bonyane lihora tse 4 ho netefatsa liphello tse nepahetseng.Haeba nako ea ho koala e le khutšoanyane haholo, katleho ea ts'ebetso e tla senyeha.Mocheso o khethehileng oa ts'ebetso le nako ea ho pata li ka khethoa ka liteko.
7. Qoba ho phunya diaphragm ho thibela tšenyo e ka 'nang ea e-ba teng ho potoloho ea ka hare ea mokokotlo oa sensor ea ceramic, e ka fellang ka ts'ebetso e sa tsitsang.
8. E-ba hlokolosi nakong ea ho kenya letsoho ho thibela litšusumetso life kapa life tse ka bakang ho se sebetse hantle ha core ea kutlo.
Ka kopo elelloa hore litlhahiso tse kaholimo tsa kopano ea sensor ea ceramic li tobane le lits'ebetso tsa k'hamphani ea rona mme li kanna tsa se sebetse joalo ka litekanyetso tsa lits'ebetso tsa tlhahiso ea bareki.
