Ƙa'idar Aiki

IQS452 yana aiki bisa ka'idar Eddy Current don cimma ma'aunin ƙaura mara lamba. Tsarin aikinsa ya ƙunshi madaidaitan matakai masu yawa waɗanda suka haɗa da shigar da wutar lantarki, daidaita siginar sigina da lalatawa, layin layi, da ramuwar zafin jiki, kowanne an fayyace ƙasa.

1. Tushen Eddy Current Sensors da Electromagnetic Induction

Jigon na'urar firikwensin eddy na yanzu shine na'ura mai ƙarfi da ke motsa shi ta babban juzu'i mai sauyawa na halin yanzu. Lokacin da aka kawo kusa da maƙasudin gudanarwa (kamar ramin ƙarfe), ana haifar da igiyoyin ruwa akan saman da ake niyya saboda shigar da wutar lantarki. A cewar Lenz's Law, waɗannan igiyoyin ruwa suna haifar da filin maganadisu mai adawa wanda ke rage tasiri mai tasiri na na'urar firikwensin. Wannan canji a cikin impedance yana da alaƙa sosai tare da tazarar tazara tsakanin firikwensin da manufa, kodayake dangantakar ba ta da tushe kuma tana tasiri ta hanyar kaddarorin lantarki na abin da ake nufi (kamar haɓakawa da haɓakawa) da zafin jiki na yanayi.

IQS452 yana haifar da siginar tashin hankali mai girma (yawanci a cikin kewayon MHz) ta hanyar oscillator na ciki. Ana watsa wannan siginar zuwa na'urar firikwensin ta hanyar kebul na coaxial mai inganci. An zaɓi babban mita don haɓaka ƙaddamar da tasirin eddy a halin yanzu a kan farfajiya (tasirin fata), don haka inganta ma'auni da ƙuduri yayin da rage tsangwama daga tsarin zurfi na kayan da aka yi niyya.

2. Canjin Sigina, Watsawa, da Rushewa

Canjin na'urar firikwensin na'urar firikwensin na'urar yana daidaita (canza) girman siginar mai ɗaukar nauyi. Wannan siginar da aka daidaita tana tafiya baya tare da kebul na coaxial zuwa kwandishan siginar IQS452. Don rage asarar sigina da tsangwama a cikin amo yayin watsa nisa, tsarin yana amfani da tsarin coaxial tare da matching impedance (yawanci 70Ω).

A cikin IQS452, siginar da aka daidaita mai girma mai dawowa an fara inganta shi. Daga nan sai a juyar da ita (yawanci ta amfani da dabarun gano lokaci-lokaci ko ambulaf), tsari mai mahimmanci wanda ke tube babban mai ɗaukar hoto don cire siginar ƙarancin mitar wutar lantarki mai ɗauke da bayanin nesa. Dole ne wannan tsari ya dawo daidai girman girman canjin impedance yayin da yake murkushe hayaniya daga jujjuyawar wutar lantarki, bambance-bambancen capacitance na USB, da tsangwama na lantarki na waje.

3. Linearization, Amplification, and Output Conversion

Siginar wutar lantarki mai ɗanɗanon daga dimodulator yana da alaƙa mara layi tare da nisa (kimanin aikin ma'auni mara kyau). Da'irar sarrafawa ta cikin gida ta IQS452 ta haɗa da keɓantaccen ƙirar layin layi wanda ke ɗaukar algorithms kamar daidaitattun nau'i-nau'i ko ramuwa na layi don juyar da siginar da ba ta dace ba zuwa daidaitaccen fitarwa wanda yake madaidaiciya sosai dangane da gibin injina.

Daga baya, ana aika siginar layin layi zuwa madaidaicin da'irar haɓakawa don daidaitawa da daidaitawa don dacewa da kewayon fitarwa da aka zaɓa:

• Yanayin Fitar da Wutar Lantarki (waya 3): Yana ba da siginar ƙarfin lantarki na madaidaiciya daga -2.4 V (daidai da mafi ƙarancin rata na 0 mm) zuwa -18.4 V (daidai da matsakaicin matsakaicin 4.0 mm). Wannan yanayin yana fasalta ƙarancin fitarwa (yawanci 500Ω) da ƙarfin hana tsangwama, yana mai da shi dacewa da watsa gajeriyar nisa zuwa katunan sayan bayanai ko PLCs.

• Yanayin Fitarwa na Yanzu (waya 2): Yana ba da siginar madauki na 4-20mA na yanzu daga 15.75 mA (0 mm) zuwa 20.75 mA (4.0 mm). Abubuwan da ake fitarwa na yanzu ba su da kariya daga faɗuwar wutar lantarki da hayaniya a kan nesa mai nisa, yana mai da shi manufa don watsawa don sarrafa ɗakuna ko tsarin DCS, kuma a zahiri yana ba da gano fashewar waya (sifilin halin yanzu yana nuna kuskure).

Dukkan hanyoyin fitarwa an tsara su tare da kariyar gajeriyar kewayawa don hana lalacewa daga ɓarna ko kuskure.

4. Matsakaicin Zazzabi da Tsarin Tsarin Tsarin

Bambance-bambancen yanayin zafi yana shafar juriya na coil, halayen kebul, da kaddarorin lantarki na abin da aka yi niyya. IQS452 yana haɗa ƙirar ramuwa ta zafin jiki, ta amfani da firikwensin zafin jiki na ciki don saka idanu zafin yanayi da algorithms don daidaita girman siginar tashin hankali ko ma'auni na da'irar lalata. Wannan yana tabbatar da tsayayyen siginar fitarwa a cikin kewayon zafin aiki da aka ƙayyade (-30°C zuwa +70°C).

Dukkanin tsarin ( firikwensin + kebul + kwandishana) an daidaita masana'anta ta amfani da madaidaicin VCL 140 karfe (1.7225) manufa a 23 ° C ± 5 ° C, yana tabbatar da musanyawa. Wannan yana nufin kowane sashi a cikin tsarin ana iya maye gurbinsa daban-daban ba tare da sake daidaita saitin gaba ɗaya ba, yana sauƙaƙe kiyaye filin sosai.

• Kyawawan Layi da Tsabtace Zazzabi: Matsakaicin layin layi na ciki da fasahar ramuwa zafin jiki suna kiyaye fitowar layin madaidaiciya da kwanciyar hankali a cikin cikakken kewayon kewayon zafin jiki, rage girman kurakurai.

4. Haƙuri mai ƙarfi da Dogara da Muhalli

• Faɗin Zazzabi: Na'urar kwandishan tana aiki da dogaro a yanayin yanayin yanayi daga -30°C zuwa +70°C, yayin da firikwensin ke jure yanayin zafi daga -25°C zuwa +140°C.

• Babban Kariya Rating: Shugaban firikwensin ya sami ƙimar kariya ta IP68 (bisa ga IEC 60529), yana ba da damar nutsewa cikin ruwa na dogon lokaci; an ƙididdige kwandishan siginar IP40, wanda ya dace da shigarwa cikin ɗakunan kulawa.

• Jijjiga da juriya na Shock: Mai kwandishan yana jure wa girgizar 2g a cikin 10-500 Hz, kuma firikwensin yana jure girgizar 5g da girgiza injin 15g (11ms rabin-sine wave), yana tabbatar da kwanciyar hankali a cikin yanayin injin girgiza sosai.

5. Sassaucin tsarin da Sauƙin Amfani

• Canjawar Na'urar: Firikwensin, kebul na tsawo, da kwandishana suna samar da tsarin da aka riga aka daidaita inda za'a iya maye gurbin abubuwan da aka gyara ba tare da sake daidaitawa ba, yana rage yawan kayan da aka keɓe da farashin kulawa.

• Zaɓuɓɓukan fitarwa da yawa: Masu amfani za su iya sassauƙa zaɓin ƙarfin lantarki ko yanayin fitarwa na yanzu dangane da yanayin wayoyi da buƙatun hana tsangwama.

• Zaɓuɓɓukan Haɗuwa da yawa: Ana iya shigar da kwandishan siginar kai tsaye ta hanyar sukurori ko zaɓin dacewa da adaftar MA130 don shigarwa akan daidaitattun hanyoyin DIN, sauƙaƙe haɗin kai.

• Zaɓuɓɓukan Kariya na Kebul: Bakin karfe na zaɓi na zaɓi 'BOA' sulke sulke da kuma FEP na waje na sheashen waje suna ba da kyakkyawan kariya ta lalata injina da juriya ga lalata sinadarai.
