• Cable Integral Pre-Shigar: Factory-welded 3-mita K205 ƙananan hayaniyar kebul tare da jagororin tashi a ƙarshen, sauƙaƙe haɗin kai tsaye zuwa na'urorin sanyaya sigina ko tsarin kulawa.

• Babu Wayar Wuta da ake buƙata: Yana rage haɗarin kurakuran shigarwa kuma yana inganta amincin tsarin.

5. Ba a Buƙatar Matsala ta gaba

• Daidaitawar Factory Dynamic Calibration: Kowane firikwensin ana daidaita shi a 120 Hz, 5 g ganiya, 23°C, tare da jurewar hankali na ± 5%. Babu gyare-gyare na lokaci-lokaci da ya zama dole.

• Kulawa da Jijjiga Injin: Irin su injin turbin gas, injin tururi, compressors, magoya baya, famfo, don lura da yanayin da gano kuskure, musamman dacewa da wurare masu ƙarancin shigarwa da wayoyi masu wahala.

• Gwajin Aerospace: Gwajin girgiza injin, nazarin tsarin tsari, kula da lafiyar abin hawa, buƙatar babban aminci da juriya mai zafi.

• Masana'antar Petrochemical: Kula da girgizar kan layi a wurare masu haɗari, kamar kayan aiki masu mahimmanci a cikin matatun mai da tsire-tsire masu sinadarai. Ƙirar kebul na haɗin kai yana rage abubuwan da ke tabbatar da fashewa, inganta tsaro.

• Ƙarfi da Makamashi: Ma'aunin girgiza don saitin janareta, injin turbin iska, kayan taimako a cikin tashoshin wutar lantarki.

• Binciken dakin gwaje-gwaje: Gwajin injiniyoyi na kayan aiki, bincike mai ƙarfi na tsari, ma'aunin girgiza mai tsayi; kebul na haɗin kai yana tabbatar da kwanciyar hankali na sigina.

• Matsanancin Muhalli na Kulawa: Kulawa na dogon lokaci na jijjiga ƙarƙashin babban zafi/ƙananan zafin jiki, babban zafi, da gurɓataccen yanayi.

IV. Ƙa'idar Aiki da Haɗin Tsarin

1. Ka'idar Aiki

CA280 yana aiki akan ƙa'idar yanayin juzu'i na piezoelectric: yawan girgizar ƙasa na ciki yana amfani da ƙarfi mai ƙarfi ga ɓangaren piezoelectric a ƙarƙashin haɓakawa, yana haifar da siginar caji daidai da haɓakawa. Sakamakon fitowar banbanta da kuma rufin ciki, wannan siginar caji tana bayyana azaman yuwuwar bambanci tsakanin fil biyu, yadda ya kamata yana murkushe tsangwama na gama-gari. A cikin sigar kebul na haɗin kai, kebul ɗin ƙaramar ƙaramar ƙarar K205 tana watsa siginar cajin banbanta daga firikwensin zuwa na'urar siginar siginar waje, kuma garkuwar kebul na ƙara danne tsangwama na lantarki.

2. Bukatun Sanya Sigina

Kamar yadda CA280 ke fitar da siginar caji mai ƙarfi, dole ne a haɗa shi zuwa mai sauya caji na waje (kamar Meggitt's IPC70x series conditioners) ko tsarin sa ido tare da shigarwar caji. Mai canza caji yana canza siginar caji zuwa siginar ƙarancin ƙarfin ƙarfi kuma yana iya samar da ayyuka kamar haɗawa da tacewa, sauƙaƙe sayan bayanai da bincike na gaba. Don sigar kebul na haɗin kai, an riga an haɗa ƙarfin ƙarfin kebul a cikin jimlar kaya; Lokacin zabar mai sauya caji, yakamata a yi la'akari da dacewarta da tsayin kebul.

3. Mabuɗin Haɗin Tsarin Tsarin

• Gyaran Kebul: Ko da yake bakin karfe ɗin da aka yi masa lanƙwasa na haɗin kebul ɗin yana da ƙarfi, har yanzu yana buƙatar gyara mai kyau don guje wa lalacewar gajiya daga girgiza. Ana ba da shawarar kiyaye kebul ɗin ta amfani da matse kusan mm 100 daga firikwensin.

• Grounding and Insulation: An haɗa akwati na firikwensin ta hanyar lantarki zuwa saman hawa, amma kewayen ciki an keɓe shi daga shari'ar. Sabili da haka, ba a buƙatar jiyya na musamman don hawa saman. Tsarin ƙasa ya kamata ya bi ka'idar ƙasa mai aya ɗaya don guje wa madaukai na ƙasa. Ya kamata garkuwar kebul ɗin ta kasance ƙasa a wuri guda, zai fi dacewa a ƙarshen mai sauya caji.

• Shigarwa a wurare masu haɗari: Lokacin amfani da shi a wurare masu haɗari, dole ne a bi sharuɗɗa na musamman daga takaddun shaida na Ex, kamar ƙayyadaddun iyawar kebul da inductance, da matakan hana tsayawa yayin shigarwa. An riga an haɗa tsayin da ma'aunin ƙarfi na kebul na haɗin gwiwa a cikin iyakokin takaddun shaida na Ex, ba tare da buƙatar ƙarin lissafi ba.

• Yin mu'amala da Tsarin Kulawa: Haɗa siginar wutar lantarki daga mai sauya caji zuwa tsarin sa ido na VM600, katunan sayan bayanai, ko samfuran shigar da analog na PLC. Sanya kewayo, madaidaitan ƙararrawa, da sauransu, ta hanyar software na daidaitawa.

• Tweaks Hardware: 116 na iya haɗawa da sabunta hanyoyin masana'antu ko abubuwan haɗin gwiwa, ba dalla-dalla a cikin takaddun jama'a ba.

• Ci gaba da Takaddun Takaddun shaida: Sigar 116 tana riƙe daidai da matakin takaddun shaidar fashewa.

2. Kwatanta da Sauran Siffofin

3. Shawarwari na Zaɓin Zaɓi

• Abubuwan Abubuwan Tsare-tsaren Tsare-tsare: Idan tsarin da ke akwai yana amfani da sigar 115, ana ba da shawarar ci gaba da siyan 115 ko tabbatar da cewa 116 na iya maye gurbinsa kai tsaye (tabbatar da girman hawan da kuma haɗin lantarki iri ɗaya ne). Tun da 115 lambar ɓangaren farko ce, ƙila an maye gurbin ta da 116; tuntuɓi Meggitt don tabbatar da dacewa yayin siyayya.

• Sabon Zaɓin Aikin: Don sababbin ayyuka, ana ba da shawarar ba da fifiko a halin yanzu nau'ikan kebul na haɗin kai (kamar 116 ko 126), kamar yadda waɗannan sigogin ke nuna sabbin hanyoyin masana'antu da tallafin fasaha mai gudana. Idan aikin yana buƙatar tsayin kebul na musamman (ban da 3m ko 6m), ya kamata a zaɓi sigar firikwensin-kawai tare da kebul ɗin da aka kawo mai amfani.

• Bukatun Zazzabi na Musamman: Idan zafin aikace-aikacen ya wuce ƙimar kebul ɗin K205 (-60°C zuwa +260°C), sigar firikwensin-kawai dole ne a yi amfani da shi tare da kebul na musamman waɗanda ke da ƙimar zafin jiki mafi girma.

• Yarda da Tabbatar da Fashewa: Ko da kuwa sigar da aka zaɓa, tabbatar da cewa alamar fashewar sa ta cika buƙatun rarraba yanki mai haɗari (misali, Yanki 0, 1, 2). Sigar kebul na haɗin kai, tare da kebul ɗin da aka riga aka shigar, yana da takaddun shaida mai fashewa wanda ke rufe taron duka, yana mai sauƙin amfani.

4. Bayanan dacewa tare da Sabbin Samfura

Jerin CA280 na iya daga baya gabatar da nau'ikan bita na kayan masarufi (misali, ƙari daban-daban), amma aikin asali ya kasance mai daidaituwa. Lokacin sauyawa ko haɗuwa, ana ba da shawarar zuwa:

• Bincika idan matakan hawa iri ɗaya ne (musamman madaidaicin ARINC 554).

• Tabbatar da hanyar fita ta kebul iri ɗaya ce (radial ko axial) don guje wa tsangwama na shigarwa.

• Tabbatar idan takaddun shaida na fashewa ya rufe yankin da ake buƙata.
