Incazelo Yokucindezeleka

Incazelo engokoqobo yenzwa yengcindezi iyithuluzi elithola amandla angokomzimba endaweni ethile bese liyihumushela kuyisiseko isignali yamandla. I-Inzwa yengcindezi ye-smartIqukethe i-silicon wafer eswela ingcindezi, yenzwa yokucindezela uketshezi, kudinga i-diaphragm ne-oyela agcwalisiwe, ne-PCB ukuguqula imininingwane kusuka ku-silicon wafer ibe yisiginali yokukhipha. Umgomo wokusebenza wenzwa yengcindezi ususelwa ebhulohweni le-Wheatstone. Isignali yamandla eyisisekelo yenzwa yengcindezi ingaba ngu-4-20 ma.

Incazelo Yokudlulisa Ingcindezi

Isidlulisi sokucindezela siqukethe inzwa yengcindezi esebenzisa i-elekthronikhi eyengeziwe ukunxephezela ukuphambuka komugqa namaphutha okushisa, imiphumela yokulinganisa yokukhipha njengamasiginali asezingeni eliphakeme. Zonke izidlulisi ezenziwe ngucheUmkhiqizi wokudlulisa ingcindeziIlinganiswa phezu kwayo yonke ingcindezi nephrofayili yokushisa futhi iqhathaniswa nesikhathi esifunwayo sesigini. Isignali yamandla aphezulu yenzwa yengcindezi ingaba ngu-0-10 V, 0.5-5V, RS485 noma amanye amasiginali okwezifiso.

Kodwa-ke, abantu abaningi basebenzisa igama lenzwa yengcindezi ukuchaza wonke amakilasi wama-transducers wengcindezi kanye nezidlulisi zokucindezela, empeleni, incazelo yokudlulisa ingcindezi ivele okokuqala emaphepheni esayensi futhi iyathandwa embuthanweni wocwaningo lwesayensi. Kodwa-ke, njengoba ukusetshenziswa kwezidlulisi zokucindezela kwaziwa emphakathini jikelele, abantu bayazimisela futhi ukusebenzisa isilulumagama samadlulisi wengcindezi.

Iyini I-transducer yokucindezela?

I-transducer yengcindezi iguqula amandla omzimba wengcindezi abe ngumkhiqizo oqhubekayo (V). Ukukhishwa kwamandla we-DC kwe-Ingcindezi yezinga lamanzi transducerImvamisa ikhuliswe ekukhipheni okujwayelekile embonini njenge-0-5V noma 0-10V. Amasiginali wokukhipha ama-Voltage, njengo-0-5 V, ayinayo i- "zero bukhoma" lapho kunesiginali lapho inzwa isengcindezi ye-zero. Ubungozi ukuthi uhlelo alwazi umehluko phakathi kwenzwa ehlulekile engenakukhipha kanye nengcindezi ye-zero. Singangeza i-interface yokuguqula ukuguqula ukuguqula isignali ibe yi-voltage esezingeni eliphezulu noma isignali yokukhipha imvamisa kufaka phakathi u-0.5 kuye ku-4.5 V ratiometris c (isignali yokukhipha iyalingana nokuhlinzekwa), 1-5V, kanye no-1-6 kHz. Lezi zimpawu zokukhipha kufanele zisetshenziswe ngaphakathi kwamamitha angamashumi amabili (20) ku-elekthronikhi. Amasiginali wokukhipha ama-Voltage anganikeza ukusetshenziswa okuphansi kwamanje kwemishini eqhutshwa ebhethri njengezinhlelo ze-SCADA. Amandla wokuphakela ngokuvamile asuka ku-8-28 VDC, ngaphandle kuka-0.5-4. Ukukhishwa kwe5V, okudinga ukunikezwa okulawulwe kwe-5VDC. Inzwa yengcindezi engaphambili

Kuyini ukucindezela?

Incazelo yezimboni neyokwemvelo yengcindezi ingamandla asetshenzisiwe ngoketshezi noma igesi ebusweni futhi imvamisa ilinganiswa ngamayunithi amandla ngayinye yendawo engaphezulu. Amayunithi ajwayelekile yiPascal (Pa), iBar (bar), iMpa, noma iPsi (amaphawunds nge-intshi skwele).

Ingcindezi ye-VS ingcindezi

Izinga lokushisa linomthelela obala ekunembileni kokulinganisa kwenzwa yengcindezi, futhi isignali yenzwa yengcindezi ayikwazi ukudluliswa ebangeni elide. Isignali eyinhloko yenzwa ithinteka kalula yimishini ye-elekthronikhi, ngakho-ke ayikwazi ukufakwa ezigcawini ezizungezwe imishini eyengeziwe ye-elekthronikhi. Intengo yenzwa yengcindezi iphansi kakhulu kunokuhanjiswa kwengcindezi. Abadlulisi bezingcindezi bakhuliswa, ngakho-ke isignali ingadluliselwa ebangeni elide ngaphandle kokuphazanyiswa kwe-elekthronikhi, futhi ukunemba kokulinganisa kungagcinwa ngaphansi kwamazinga okushisa amakhulu ngemuva kwesinxephezelo sezingenisa.
