Ƙa'idar Aiki
Ayyukan na'urar watsa TWW 103 M1 ya dogara ne akan tasirin eddy na yanzu, tushe na zahiri na ma'aunin ƙaura mara lamba. Cikakken tsarin aunawa ya ƙunshi WW 018 eddy firikwensin kusancin halin yanzu (bincike) da mai watsa TWW 103 M1.
1. Eddy Current Effect and Signal Generation:
Shugaban firikwensin WW 018 ya ƙunshi coil. Lokacin da babban mitar halin yanzu daga mai watsawa ya wuce ta wannan nada, yana haifar da babban filin lantarki. Idan wannan firikwensin yana nufin maƙasudin ƙarfe na ƙarfe (misali, saman shaft), wannan filin na lantarki yana haifar da igiyoyin ruwa a saman abin da ake nufi. Waɗannan magudanar ruwa, bi da bi, suna haifar da sabon filin maganadisu wanda ke adawa da na asali, yana tsayayya da canje-canje a cikin filin farko, wanda saboda haka ya canza rashin ƙarfi na na'urar firikwensin. Girman wannan canji na impedance yana da alaƙa kai tsaye da nisa tsakanin tip na bincike da farfajiyar da aka yi niyya: mafi kusa da nisa, mafi karfi da tasiri kuma mafi girma canjin impedance; Nisa mafi nisa, mafi raunin tasiri kuma ƙarami yana canzawa.
2. Sigina Conditioning da Processing:
Babban aikin mai watsawa shine ganowa da aiwatar da wannan canjin naƙasa wanda ya haifar da bambancin nesa. Wurin kewayawa na ciki yana aiwatar da waɗannan mahimman matakai:
Ƙaddamar da siginar: Yana karɓar siginar siginar RF mai sauƙi daga firikwensin kuma yana jujjuya shi zuwa siginar wutar lantarki na DC wanda shine aikin nesa.
Linearization: Dangantakar da ke tsakanin nisa da siginar wutar lantarki da aka haifar da tasirin eddy na yanzu ba daidai ba ne. Da'irar layin layi na cikin mai watsawa yana rama wannan, yana tabbatar da fitowar ta ƙarshe tana da alaƙa mai tsayin gaske tare da ainihin nisa.
Tace: Mai watsawa yana haɗa matattara mai ƙarancin wucewa tare da mitar yanke (fo) na 5 Hz da jujjuyawar 20 dB/shekaru. An ƙera wannan matattarar don adana siginar DC ko ƙananan-ƙananan sigina waɗanda ke nuna jinkirin sauye-sauye a matsayi na shaft yayin da yake murkushe hayaniyar girgiza mai ƙarfi da sauran tsangwama na lantarki, yana tabbatar da tsayayyen siginar fitarwa mai tsafta wanda ke nuna daidai daidaitaccen matsayi na shaft.
Canza sigina & Fitarwa: Siginar wutar lantarki da aka sarrafa, madaidaiciyar siginar siginar tana canzawa zuwa daidaitaccen siginar analog na yanzu na 4-20mA. Siffa ta musamman ta TWW 103 M1 ita ce tanadar ta na masu zaman kansu guda biyu, abubuwan da aka keɓe na 4-20 mA:
Babban Fitowa (Lokacin 500 Ω): Tsakanin tashoshi 3-4. An sadaukar da wannan siginar don saka idanu na inji, ana watsa shi zuwa dakin sarrafawa ko tsarin kulawa.
Fitowar Taimako (Lokaci 25 Ω): Tsallake tashoshi 6-7. Wannan siginar an yi niyya ta musamman don taimakawa wurin sanya firikwensin yayin shigarwa da ƙaddamarwa. Masu fasaha na iya haɗa ammeter šaukuwa (load <25Ω) zuwa wannan fitarwa akan rukunin yanar gizon don karanta ƙimar matsayi a cikin ainihin lokacin, yana ba da damar daidaita daidaitaccen firikwensin zuwa ratar aiki da aka saita (yawanci daidai da takamaiman ƙarfin fitarwa ko ƙimar halin yanzu) ba tare da dogaro da babban tsarin kulawa a cikin ɗakin kulawa ba.
3. Halayen fitarwa:
Yana da mahimmanci a lura cewa yanayin fitarwar mai watsawa ya bambanta: abin da ake fitarwa yana raguwa yayin da nisa ke raguwa (gap yana rufe) kuma yana ƙaruwa yayin da nisa ke ƙaruwa (rabin yana buɗewa). Takamaiman wasiku shine: 0 mm rata yayi daidai da 20 mA, 10 mm rata yayi daidai da 4 mA.
4. Kulawa da Kai & Binciken Laifi:
Mai watsawa ya haɗa da kewayen sa ido na ciki wanda ke ci gaba da bincika:
Buɗe kewayawa ko gajeriyar kewayawa a cikin firikwensin ko kebul ɗin sa.
Makasudin kasancewa mai mahimmanci a waje da ingantaccen kewayon ma'aunin firikwensin.
Bayan gano duk wani laifi, mai watsawa nan da nan yana fitar da kayan aikin analog na yanzu zuwa 0 mA kuma yana haskaka ja Fault LED akan gaban panel, yana ba da alamun ƙararrawa na gida da na nesa, yana haɓaka amincin tsarin.
