Lefoo I-Monocrystalline

Isimiso Sokusebenza seLefoo Monocrystalline

Imodyuli yenzwa yamukela ubuchwepheshe bonke be-welding futhi ine-diaphragm ehlanganisiwe, inzwa yengcindezi kanye nenzwa yokushisa ngaphakathi. Inzwa yokushisa isebenza njengesethenjwa yesinxephezelo sokushisa. Uhlangothi lwengcindezi enhle yenzwa yengcindezi luxhunywe kwigumbi lokucindezela eliphezulu le-sensor diaphragm, futhi uhlangothi lwengcindezi engemihle yenzwa luxhunywe kwigumbi lokucindezela eliphansi le-diaphragm yenzwa. Inani lokumelana ne-chip liyashintsha, okuholela ekushintsheni kwamandla okukhipha ohlelweni lokutholwa. Amandla okukhipha alingana nokushintshwa kwengcindezi, bese aguqulwa abe ngumkhiqizo wesiginali ojwayelekile yiyunithi yokuzivumelanisa kanye ne-amplifier.

Indlela I-Lefoo Monocrystalline

E-Lefoo, enye yesiphezuluAbahlinzeki abaphambi kwengcindezi, Izinzwa zokucindezela zePiezoresistive zakhiwa kusetshenziswa umphumela we-piezoresistive we-crystal silicon eyodwa. Usebenzisa i-crystal silicon wafer eyodwa njengento e-elastic, ubuchwepheshe besifunda obuhlanganisiwe busetshenziswa kwifilimu eyodwa ye-crystal silicon ukusabalalisa isethi yama-resers efanayo Isiqondiso esithile se-crystal silicon eyodwa, nama-resistiors axhunywe kwisekethe yebhuloho, futhi i-crystal silicon wafer eyodwa ibekwa ngaphakathi ngaphakathiIzinzwa zokucindezela ezihlukile ze-HVACIndawo.

Lapho ingcindezi ishintsha, i-crystal silicon eyodwa ikhiqiza uhlobo, ukuze ukumelana kobunzima okusatshalaliswe ngqo kuyo kushintshe ngokulingana nengcindezi elilinganisiwe, bese kuthi isekethe yebhuloho ithola isignali yokukhipha amandla okuhambisana.

Ukuhlolwa kwesilinganiso seLefoo Monocrystalline Silicon Pressure Transmitter

1. Susa i-flange bese uhlola ukuthi i-diaphragm ehlukanisayo yengxenye ebucayi ikhubazekile yini, ukuvuza okulimale noma kukawoyela kwenzeka.

2. Susa ibhodi lesinxephezelo ngaphandle kokukhipha izingxenye ezibucayi, bese uhlola ukumelana nokufakwa kwe-plug ezindlini. Lapho i-voltage ingadluli i-100 V, ukumelana kokufakwa akufanele kube ngaphansi kuka-100 MΩ.

3. Xhuma isekethe yesekethe negesi, lapho isignali yengcindezi ingumkhawulo ophezulu webanga, cima umthombo wegesi, futhi amandla okukhipha nenani lokufunda kufanele azinze. Uma i-voltage yokukhipha yehla, kusho ukuthi isidlulisi siyavuza, ungahlola ukuvuza ngamanzi ensipho.

Ukuhlolwa Kwesekethe kweLefoo Monocrystalline Silicon Pressure Transmitter

1. Vumela amandla bese uhlola isimo sesiginali yamandla ku-transmitter. Uma kungekho amandla okukhipha, kufanele uqale uhlole ukuthi ngabe i-voltage yokuphakela ugesi ijwayelekile yini; ngabe ihlangabezana nezidingo zokuphathwa kwamandla; ngabe kukhona iphutha lezintambo phakathi kokuphakelwa kwamandla kanye nomthumeli nemishini yokulayisha. Uma kungekho voltage kutheminali ye-transmitter noma i-polarity ibuyiselwe emuva, ingadala i-transmitter ukuthi ingakhiphi isignali yamandla. Uma izizathu ezingenhla zingakhishwa, kuyadingeka ukuqhubeka nokuhlola ukuthi ngabe izingxenye ezisesekethe yebhodi le-amplifier zilimale yini; ukuthi izixhumi zebhodi lesifunda ziyaxhumana kabi, Ungaqhathanisa amandla alinganisiwe wensimbi ejwayelekile namandla alinganisiwe ahambelana nensimbi eyiphutha yokuthola iphutha. Uma kunesidingo, shintsha ibhodi le-amplifier elinephutha. Lapho uhlola isidlulisi sohlobo lokugeleza, ukunakwa okukhethekile kufanele kuthathwe izinyathelo zokulwa nezindawo zebhodi le-J-type amplifier.

2. Vula ukuphakelwa kwamandla, ngemuva kokunikezwa kwesiginali yengcindezi yokufaka, uma ukukhishwa kwe-transmitter kuphezulu kakhulu (kukhulu kune-10 VDC), noma okukhiphayo kuphansi kakhulu (ngaphansi kuka-2.0 VDC), Futhi okukhiphayo kufana konke lapho kuguqulwa isignali yengcindezi yokufaka nokulungisa iphoyinti le-zero kanye nezikulufu zebanga Akukho kusabela. Kulolu hlobo lwephutha, ngaphezu kokuhlola ukuthi ngabe izingxenye ezibucayi zengxenye yokulinganisa yesithumbi azijwayelekile yini, hlola ukuthi "ingxenye yesekethe yokulawula i-oscillation" ebhodini le-amplifier le-transmitter isebenza ngokujwayelekile noma cha. I-voltage ejwayelekile phakathi kwe-transformer yemvamisa ephezulu T1-12 kufanele ibe ngu-25 ~ 35VP-P; imvamisa icishe ibe ngama-32 kHz. Okwesibili, hlola isimo sokusebenza sokukhulisa ngasinye kubhodi le-amplifier; noma ngabe izingxenye zengxenye ngayinye zilimale noma cha. Ukwehluleka okunjalo kudinga ukushintshwa kwebhodi le-amplifier.

3. Isidlulisi sinezidingo eziqinile kakhulu ekwakhiweni kwesifunda kanye nekhwalithi yomhlangano. Ngokusetshenziswa kwangempela, kumaphutha wesifunda ezenzeka, kungcono ukuxhumana nomkhiqizi ukuze ungene esikhundleni sebhodi lesifunda elinephutha ngemuva kokuhlolwa nokuqinisekiswa ukuqinisekisa isikhathi esideUkusebenza kwensimbi. Ukuzinza nokuthembeka.

Ukuxazululwa kwesiza

1. Into eyinhloko ivinjiwe noma ifomu lokufakwa alilungile, futhi iphuzu lokucindezela alinangqondo.

2. Ukudilizwa noma ukuvinjelwa kwepayipi lokushaya, igesi eseleyo kuphayipi lokugcwalisa uketshezi noma uketshezi olusele kupayipi lokushaja igesi, kanye nendawo ku-flange yenqubo yokudlulisa, kwakha indawo efile yokulinganisa.

3. Intambo yokudlulisa ayilungile, amandla okuphakela ugesi aphezulu kakhulu noma aphansi kakhulu, futhi ukuxhumana phakathi kwekhanda lenkomba ne-terminal yensimbi kuxhumana kabi.

4. Ayifakiwe ngokuqinile nezidingo zobuchwepheshe, futhi indlela yokufakwa nemvelo yesayithi ayihlangabezani nezidingo zobuchwepheshe.
