Liketane tsa tekanyo ea ho lekanya haufi le TQ9xx li lumella tekanyo e sa amaneng ea phallo e lekanyelitsoeng ea likarolo tsa mochini o tsamaeang, 'me e fana ka pontšo e lekanang le sebaka se pakeng tsa ntlha ea sensor le sepheo. Ka hona, liketane tsena tsa litekanyo li loketse hantle bakeng sa ho lekanya ho sisinyeha ho lekanyelitsoeng le boemo ba axial ba li-shafts tsa mochini o potolohang, joalo ka tse fumanoang ka har'a mouoane, khase le li-hydraulic turbines, hammoho le li-alternator, li-turbo-compressors le lipompo. Ketane ea tekanyo ea proximity e thehiloeng ho TQ9xx e na le sensor ea TQ9xx ea proximity, thapo ea boikhethelo ea EA90x le IQS900, e lokiselitsoeng ts'ebeliso e itseng ea indasteri. Mohala oa katoloso oa EA90x o sebelisoa ho lelefatsa pheletso e ka pele, joalo ka ha ho hlokahala. Ka kopanelo, tsena li theha ketane e lekantsoeng ea proximity proximity ketane eo ho eona karolo ka 'ngoe e ka fapanyetsanoang.

Karolo e sebetsang ea TQ9xx proximity sensor ke khoele ea terata e bōpiloeng ka hare ho ntlha ea sesebelisoa, e entsoeng ka PPS (polyphenylene sulfide), e sebetsang hantle, e phahameng ea mocheso oa mocheso oa thermoplastic. 'Mele oa sensor o entsoe ka tšepe e sa hloekang. Thepa e reretsoeng, maemong 'ohle, e lokela ho ba tšepe. Li-sensor tsa TQ902 le TQ912 tsa proximity li hlile li ts'oana ntle le hore TQ902 e etselitsoe maemo a holimo mme TQ912 ke ea lits'ebetso tse khutlisetsang morao. Ka bobeli li-sensor li fumaneha ka likhoele tsa metric kapa tsa moemphera 'me li na le thapo e kopaneng ea coaxial e felisitsoeng ka sehokelo se senyenyane sa coaxial se itšebetsang. Thapo ea bohlokoa ea sensor ea TQ9xx le likhoele tsa katoloso ea EA90x li fumaneha ka bolelele bo fapaneng, tse ka kopanngoang ho fumana bolelele bo itseng ba sistimi (TSL) bakeng sa kopo. Litšireletso tsa boikhethelo tsa likhokahano (IP172), mabokose a mateano (JB118) le matlo a mang a teng bakeng sa ts'ireletso ea mochini le tikoloho ea khokahano lipakeng tsa thapo e kholo ea sensor ea TQ9xx le thapo ea katoloso ea EA90x.

Habohlokoa ka ho ts'oanang, liketane tsa ho lekanya tse thehiloeng ho TQ9xx tse sebelisang IQS900 tse nang le tlhahlobo ea mafu ke SIL 2 "ka moralo" kahoo li tlisa ts'epo e matlafalitsoeng le phokotso e kholo ea kotsi, e etsa hore li tšoanelehe ho sebelisoa lits'ebetsong tse amanang le polokeho (maemo a ts'ireletso a ts'ebetso). Ho feta moo, liketane tsa litekanyo tse thehiloeng ho TQ9xx li entsoe ka sebopeho, li lekana ebile li sebetsa ka mokhoa o ts'oanang tse tsamaisanang kapa tse betere ts'ebetso e ntle ea liketane tsa tekanyo tse thehiloeng ho TQ4xx. Karolo e 'ngoe le e' ngoe e ka feto-fetoha, kahoo liketane tse teng tsa TQ4xx tse thehiloeng ho proximity li ka nkeloa sebaka ka potlako le habonolo kapa tsa ntlafatsoa. Mohlala, IQS900 sign conditioner ntle le tlhahlobo ke phetisetso e tobileng ea IQS45x ho boholo ba liketane tsa tekanyo tse thehiloeng ho TQ4xx. Tlhokomeliso: Ketane ea ho lekanya e thehiloeng ho TQ9xx e sebelisang IQS900 e hlophisitsoeng ka tlhahiso ea hona joale le yuniti ea karohano ea galvanic ea GSI127, e lumella phetisetso ea libaka ho fihlela ho 1 km - nako e telele ho feta tharollo leha e le efe.
