4: Ukuthi i-wiring ivulekile yini; Isixazululo: Xhuma izintambo bese usiqinisa 5: Ngabe intambo yamandla inentambo kahle? Isixazululo: Intambo yamandla kufanele ixhumeke kwi-POST ehambisanayo ye-terminal
3: aout≤4MA
1: Ingabe ukudlulisela amandla okudlulisela okujwayelekile okujwayelekile? Isixazululo: Uma kungaphansi kwe-12VDC, hlola ukuthi kunomthwalo omkhulu esisekelweni. Okufakwayo komthwalo we-transmitter kufanele kuhlangane ne-RL ≤ (Transmitter Power Supply Voltage -12V) / (0.02a) ω
2: Ngabe ingcindezi yangempela idlula uhla olukhethiwe lokudlulisela kwengcindezi; Isixazululo: Khetha kabusha ukudluliselwa kwengcindezi ngebanga elifanele
3: Ngabe inzwa yokucindezela yonakele? Ukulayisha ngokweqile kwesinye isikhathi kungalimaza i-lolate diaphragm. Isixazululo: Kudinga ukulandela umkhiqizi wokulungiswa.
4, inkomba engalungile yokucindezela
1: Ingabe ukudlulisela amandla okudlulisela okujwayelekile okujwayelekile? Isixazululo: Uma kungaphansi kwe-12VDC, hlola ukuthi kunomthwalo omkhulu esisekelweni. Okufakwayo komthwalo we-transmitter kufanele kuhlangane ne-RL ≤ (Transmitter Power Supply Voltage -12V) / (0.02a) ω
2: Ngabe inani lengcindezi yereferensi lilungile? Isixazululo: Uma ukunemba kwegeji yereferensi kuphansi, kuyadingeka ukuyibuyisela esikhundleni se-eRecracy Pressure Gauge.
3: Uhla lwengcindezi ekhombisa ithuluzi elihambisana nobubanzi be-Transmitter yengcindezi? Isixazululo: Uhla lwengcindezi ekhombisa ithuluzi okukhombisa ukuthi lihambisane nobubanzi be-Transmitter yengcindezi
4: Ingabe ukufakwa okufakwayo kanye ne-wiring ehambelana nengcindezi ekhombisa ukuthi ithuluzi lilungile? Isixazululo: Uma okokufaka kwengcindezi ekhombisa ithuluzi kungu-4-20m-20ma, isibonakaliso sokukhipha se-transmitter singaxhunyaniswa ngqo; Uma okokufaka kwengcindezi ekhombisa ithuluzi kungu-1-5v, ukumelana nokunemba kwenkulungwane eyodwa noma ngaphezulu kanye nenani lokumelana ne-250 ω kumele kuxhunywe ekupheleni kwengcindezi ekhombisa ithuluzi.
5: Ukuvikelwa kokufakwa komthwalo we-transmitter kufanele kuhambisane ne-RL ≤ (Transmitter Voltage -12V) / (0.02A) / (0.02A) / (0.02A) / (0.02a)
I-6: Bheka ukuthi ngabe i-terminal yokufaka yerekhoda yamaphepha amaningi ivulekile uma kungekho okurekhodiwe; Isixazululo: Uma kukhona umjikelezo ovulekile: a. Ayikwazi ukuthwala eminye imithwalo; b. Sebenzisa elinye iRekhodi ngokuvinjwa kokufakwa ≤ 250 ω lapho kungekho irekhodi.
7: Ingabe imishini ehambelana ehambelana icwebezela? Isixazululo: I-Exparment Casing Ingceme
8: Ukuthi uhlukanise i-wiring kusuka kumandla we-AC nakwezinye izixazululo zamandla
9: Ngabe inzwa yokucindezela yonakele? Ukulayisha ngokweqile kwesinye isikhathi kungalimaza i-lolate diaphragm. Isixazululo: Kudinga ukulandela umkhiqizi wokulungiswa.
10: Noma ngabe kukhona isihlabathi, ukungcola, njll. Ukuvimba ipayipi, okungathinta ukunemba kokulinganisa; Isixazululo: Kuyadingeka ukuhlanza ukungcola futhi ungeze isikrini sokuhlunga phambi kwesibonisi sokucindezela.
11: Ingabe izinga lokushisa lepayipi liphezulu kakhulu? Ukushisa okusebenzayo kwe-sensor yengcindezi kungu -25 ~ 85 ℃, kepha ekusetshenzisweni kwangempela, kungcono ukuba sendaweni -20 ~ 70 ℃. Isixazululo: Faka ishubhu le-buffer ukuqeda ukushisa. Kungcono ukwengeza amanye amanzi abandayo ngaphakathi kwe-buffer tube ngaphambi kokuvimbela ukweqisa umusi kusuka ekutholeni ngqo inzwa, ngaleyo ndlela kulimaze inzwa noma ukunciphisa impilo yayo yenkonzo.
