Dad badan ayaa caadi ahaan ku qalda gudbiyaasha cadaadiska iyo dareemayaasha cadaadiska isku mid, kuwaas oo u taagan dareemayaasha. Dhab ahaantii, aad bay u kala duwan yihiin.
Qalabka cabbiraadda korontada ee ku jira qalabka cabbiraadda cadaadiska waxaa loo yaqaannaa dareenka cadaadiska. Dareemayaasha cadaadisku waxay guud ahaan ka kooban yihiin dareemayaasha laastikada iyo dareemayaasha barokaca.
1. Shaqada curiyaha xasaasiga ah ee laastikada waa in cadaadiska la qiyaasay uu ka dhigo meel gaar ah oo uu u beddelo barokac ama cadaadis, ka dibna u beddelo signalka korantada ee la xidhiidha cadaadiska iyada oo la raro curiyaha xasaasiga ah ama cabbirka cadaadiska. Mararka qaarkood shaqooyinka labadan walxood ayaa la isku daraa, sida dareeraha cadaadiska gobolka adag ee dareenka piezoresistive.
2. Cadaadisku waa halbeeg muhiim u ah habka isticmaalka iyo hawada, duulista iyo warshadaha difaaca qaranka. Ma aha oo kaliya inay u baahan tahay inay joojiso cabbirka degdega ah ee firfircoon, laakiin sidoo kale si dhijitaal ah u muuji oo u diiwaangeliso natiijooyinka cabbirka. Automation-ka warshadaha saliida ee waaweyn, dhirta kiimikaad, dhirta tamarta iyo birta iyo dhirta birta waxay sidoo kale u baahan tahay inay gudbiso cabbirada cadaadiska waqtiyo dheer, oo ay codsato in loo beddelo cadaadiska iyo cabbirrada kale, sida heerkulka, socodka iyo viscosity, oo loo beddelo calaamadaha dhijitaalka ah iyo u dir kombayutarka.
3. Dareemka cadaadisku waa nooc dareeme ah oo aad loo qiimeeyo oo si degdeg ah u horumaray. Isbeddelka horumarinta dareenka cadaadiska waa in la sii wanaajiyo xawaaraha jawaabta firfircoon, saxnaanta iyo isku hallaynta, iyo dhammaystirka digitization iyo sirdoonka. Dareemayaasha cadaadiska caadiga ah waxaa ka mid ah dareeraha cadaadiska capacitive, dareeraha cadaadiska cago-jiidka ee doorsooma, dareeraha cadaadiska hoolka, dareeraha cadaadiska fiber-ka, dareemayaasha cadaadiska resonant, iwm.
Waxaa jira noocyo badan oo gudbiyeyaal ah. Gudbiyeyaasha loo isticmaalo qalabka xakamaynta warshadaha inta badan waxaa ka mid ah gudbiyaha heerkulka, gudbiyaha cadaadiska, gudbiyaha socodka, gudbiyaha hadda, gudbiyaha korantada iyo wixii la mid ah.
1. Gudbiyehu waxa uu u dhigma cod-weyneeye. Gudbiyaha AC220V ee aan isticmaalno waxay siisaa danabka buundada dc10v ee dareemayaasha, ka dib waxay helaysaa calaamadda jawaab celinta, way kordhisaa oo soo saartaa 0V ~ 10V danab ama calaamad hadda jirta. Waxa kale oo jira gudbiyeyaal yar yar oo DC24V ah, kuwaas oo u badan sida dareemayaasha oo mararka qaarkood la wada rakibo. Guud ahaan, gudbiyaha ayaa awood siiya dareemayaasha oo uu sii kordhiyaa calaamada. Dareemuhu waxa uu ururiyaa oo kaliya calaamadaha, sida cabbirka cadaadiska, kaas oo u beddela calaamada barokaca ee calaamadda iska caabinta. Dabcan, waxaa jira dareemayaal aan lahayn koronto, sida thermocouples iyo ceramics piezoelectric, kuwaas oo inta badan la isticmaalo.
2. Waxaan isticmaalnay noocyo kala duwan oo dareemayaasha cadaadiska, laakiin gudbiyaha si dhib leh looma beddelin. Dareemaha cadaadiska ayaa ogaanaya calaamadda cadaadiska, guud ahaan tixraacaya mitirka aasaasiga ah. Gudbiyaha cadaadiska wuxuu isku daraa mitirka aasaasiga ah iyo mitirka sare, wuxuuna u beddelaa calaamadda la ogaaday heerka 4-20, 0-20 Ma ama 0-5V, 0-10V. signalka, iyo gudbiyaha ma dareemayo oo kaliya, laakiin sidoo kale "wuxuu noqdaa" signalka caadiga ah ka dibna "soo diro" dibadda.
Dareemka cadaadiska guud ahaan waxaa loola jeedaa walxaha xasaasiga ah ee u beddela calaamadda cadaadiska isbeddelay ee u dhiganta calaamadda iska caabbinta isbeddelay ama calaamadda awoodda, sida element piezoresistive, element piezocapacitive, iwm. walxaha cadaadiska-xasaasiga ah iyo wareegga qaboojinta. Guud ahaan, waxay si toos ah u soo saari kartaa calaamada korantada caadiga ah ama calaamada hadda jirta ee xidhiidhka tooska ah ee leh cadaadiska tooska ah ee ururinta qalabka, PLC, kaarka iibsiga iyo qalabka kale.
Ma rabtaa inaad nala shaqeyso?
