Ilungele i-Dongfeng cummins oil presport sensor 4921489

1. Yini inzwa yokucindezela?

Inzwa yengcindezi yinoma iyiphi ithuluzi elithola ingcindezi elinikezwe ngalo yinto noma umzimba. Inani lokucindezela kudivayisi lingalinganiswa yithonya laso enzwaneni. Izinzwa zingaba yidijithali noma i-analog, kepha nganoma iyiphi indlela, zingathumela isibonakaliso sokufunda senani elithile lokucindezela endaweni ekude.

Igama elithi "inzwa" libuye libe yisikhathi esijwayelekile nelijwayelekile ngezinga elithile, kufaka phakathi imishini ethile, njenge-transdumers kanye nama-transmitters. Ngamanye amagama, yize zonke izingcindezi zokudlulisa izingcindezi zingama-sensor, akuzona zonke izinzwa zokucindezela zingama-transducers. Ungabhekisa kwizakhi zesistimu yokulinganisa ezithinteke ngqo ingcindezi njenge- "Sensors", kunezakhi ezizimele zohlelo eziguqula lolu lwazi zibe amasiginali kagesi.

2. Isebenza kanjani inzwa yokucindezela?

Njengomshini we-elektrolokhethi, inzwa yokucindezela ingabona futhi ibheke ingcindezi ohlelweni lwamanzi ngokuguqula amandla ngokomzimba kudivayisi ibe isibonakaliso sikagesi.

Inzwa eyinkimbinkimbi yokucindezela iyingxenye yohlelo olukhudlwana, olungafundzeli kuphela lelo zinga lokucindezela elisetshenziswe ohlelweni, kepha empeleni libhekele ukuqapha kanye nokulawula uhlelo ukuphendula izinga lokutholwa kwengcindezi. Ngokushintsha kwengcindezi, ukuphuma kwesiginali senzwa nakho kuzoshintsha. Lokhu kungadala ukulawula kulungiselelwe ukuvula, ukucisha noma ukuguqula izinga lezakhi zohlelo kwamanye amaphuzu atholwayo.

3. Yini i-transducer yokucindezela?

Ingcindezelo ye-TransDucer uhlobo lwezinzwa zokucindezela, ezihlanganiswa ngento ebucayi yengcindezelo kanye nento yokuguqula yesiginali. I-transducer iguqula isibonakaliso sikagesi esisezingeni eliphansi kusuka ekucindezelweni okufakwayo (kusuka kugesi noma uketshezi) ku-voltage voltage noma i-milliamppere okukhipha. "Ukuguqulwa" kusho "ukuguqulwa".

4. Uyini umsebenzi wengcindezelo transducer?

I-transducer ifunda ingcindezi ohlelweni lwamanzi. Ngemuva kwalokho, ukukhishwa kwamandla kagesi noma kwamanje kwe-transducer kungadluliselwa endaweni ekude yokuqapha nokwazisa okuzenzakalelayo noma okulawulwayo okulawulwa kohlelo. Izinhlobo zemiphumela ye-Analogi zifaka: 4-20 Ma, 0-5 VDC, 0-10 VDC, 1Vac noma 0.3333VAC. Uma usebenzisa i-Digital Pressuctor Transmucer (AKA Pressure Transmitter), imishini ye-elekthronikhi ethuthukisiwe enganikeza umsebenzi wokuthumela amasiginali ngokusebenzisa imigomo yokuxhumana yezimboni efana ne-modbus noma i-bacnet.

5. Omile futhi omanzi ingcindezi yokucindezela

I-transcucer esomile yokucindezela ilinganisa umehluko wengcindezi endaweni eyomile (njengohlelo lwePipeline yomoya noma lwegesi), ngenkathi i-transducer ethambile ephakathi nendawo izovumela ingcindezi yokuzwa ngohlelo olumanzi (njengepayipi).
