Ku habboon Dongfeng Cummins Cuntada Cadaadiska Saliida ee 4921489

1. Waa maxay dareenka cadaadiska?

Dareeraha cadaadiska ayaa ah qalab kasta oo ogaada cadaadiska ku dul saaray walax ama jir. Cadadka cadaadiska ee aaladda waa la fahmi karaa iyada oo saameyntiisa ku leh dareenka dareeraha. Dareemadu waxay noqon kartaa digital ama analog, laakiin si kasta ha ahaatee, waxay u diri karaan seenyaalaha akhriska ee qiimaha cadaadiska gaarka ah ee goob fog.

Ereyga "dareenka" sidoo kale waa eray guud oo guud oo ilaa xad ah, oo ay ku jiraan qalab gaar ah oo dheeraad ah, sida guddiyada iyo kuwa la isweydaarsanayo. Si kale haddii loo dhigo, in kasta oo dhammaan cadaadiska cadaadiska ay yihiin dareemayaal, dhammaan dareemayaasha cadaadiska ee dhammaantood waa isku-darka. Waxa kale oo aad u tixraaci kartaa qaybaha cabbiraadda nidaamka cabbiraadda si toos ah cadaadis loogu sameeyo "dareemayaasha", halkii aad ka noqon lahayd qaybaha madaxa-bannaan ee nidaamka u beddela macluumaadkan calaamadaha elektiroonigga ah.

2. Sidee cadaadishku u shaqeeyaa?

Sida aaladda elektaroonigga ah, dareeraha cadaadiska ayaa lagu ogaan karaa waxayna la socon kartaa cadaadiska nidaamka dheecaanka asaga oo u beddelaya xoogga jirka aaladda aaladda korantada.

Dareer cadaadis adag ayaa qayb ka ah nidaam ballaadhan, oo aan akhrin oo keliya heerka cadaadiska ee lagu dabaqayo nidaamka, laakiin dhab ahaantii mas'uul ka ah la socodka iyo xakamaynta nidaamka si looga jawaabo heerka cadaadiska ee la soo saaray. Iyada oo isbedelka cadaadiska, wax soo saarka calaamadda ee dareeraha ayaa waliba is beddeli doona. Tani waxay kicin kartaa kontaroolada loo habeeyey inuu shido, damiyo ama hagaajiyo heerka qaybaha nidaamka ee qaar ka mid ah qodobbada la soo saaray.

3. Waa maxay Cadaadiska Cadaadiska?

Transducer cadaadisku waa nooc ka mid ah dareenka cadaadiska cadaadiska, kaasoo ka kooban cuncun xasaasi ah oo cadaadis ah iyo element beddelka. Transduchur wuxuu u beddelaa calaamad koronto oo heer hoose ah ka soo jeedinta cadaadiska farsamada (gaaska ama dareeraha) korantada isku-darka ah ama wax soo saarka milliamperal. "Beddelka" macnaheedu waa "isbadal".

4. Waa maxay shaqada cadaadiska cadaadiska?

Transduchur wuxuu aqriyaa cadaadiska nidaamka dareeraha. Kadib, korantada ama wax soo saarka hadda ee transducer waxaa loo gudbin karaa meel fog oo loogu tala galay korjoogteynta iyo wargelinta otomatiga ama gacanta ee nidaamka. Noocyada wax soo saarka analogga waxaa ka mid ah: 4-20 MA, 0-5 VDC, 0-10 VDC, 1vac ama 0.333vac. Haddii aad isticmaasho transducer cadaadis dijital ah (cadaadiska cadaadiska cadaadiska ee horumarsan), qalab koronto oo horumarsan ayaa bixin kara howsha dirista calaamadaha isgaarsiinta warshadaha sida Modbus ama Bacnet.

5. Xadgudubka qallalan oo qoyan oo qoyan

Transducer cadaadis qallalan ayaa cabiraya farqiga cadaadiska ee dhexdhexaad ah (sida nidaamka dhuumaha gaaska ama gaaska), halka xargaha cadaadiska gaaska ee qoyan uu u oggolaado dareenka cadaadiska ee nidaamka qoyan (sida dhuumaha).
