Ukuhlaziywa Kwezimiso Kwezinhlobo Ezehlukene ZamaSensors Womfutho

Table of Content [Hide]

Inzwa yengcindezi iyona nzwa esetshenziswa kakhulu emisebenzini yezimboni. Isetshenziswa kakhulu ezindaweni ezihlukahlukene zokulawula okuzenzakalelayo kwezimboni, okuhlanganisa ukongiwa kwamanzi namandla kagesi, ezokuthutha ngezitimela, izakhiwo ezihlakaniphile, ukulawulwa okuzenzakalelayo kokukhiqiza, umkhathi, ezempi, amakhemikhali namafutha, imigodi kawoyela, ugesi, imikhumbi, imishini yokusebenza, amapayipi kanye nezinye izimboni eziningi, okulandelayo incazelo emfushane yezimiso kanye nokusetshenziswa kwezinzwa ezithile ezijwayelekile.

Inzwa yengcindezi iyisisetshenziswa noma idivayisi ekwazi ukuzwa izimpawu zengcindezi futhi iguqule izimpawu zengcindezi zibe izimpawu zikagesi eziphumayo ezingasebenziseka ngokwemithetho ethile. Inzwa yengcindezi ngokuvamile yakhiwe yingxenye ezwela ingcindezi kanye neyunithi yokucubungula izimpawu.

1. Piezoresistive pressure sensor

I-resistance strain gauge ingelinye lezingxenye eziyinhloko ze-piezoresistive pressure sensor. Isimiso sokusebenza kwe-metal resistance strain gauge yisimo lapho inani lokumelana ne-strain resistance enamathele ezintweni eziyisisekelo lishintsha ngenxa yokuguquguquka komshini, okuvame ukubizwa ngokuthi i-resistance strain effect.

2. Ceramic pressure sensor

The ceramic pressure sensorisekelwe emthelela we-piezoresistive. Ingcindezi isebenza ngokuqondile ebusweni bangaphambili be-diaphragm ye-ceramic, okwenza ukuguquguquka okuncane kwediaphragm. I-thick film resistor iphrintiwe ngemuva kwe-ceramic diaphragm futhi ixhunywe ebhulohweni i-Wheatstone. Ngenxa ye-piezoresistor kanye nomthelela we-piezoresistive, ibhuloho likhiqiza isignali yamandla kagesi e-line kakhulu elingana nengcindezi futhi elilingana namandla kagesi okukhuthaza. Isignali ejwayelekile ihlolwa ngokwezinga elingu-2.0/3.0/3.3mV/V ngokwebanga lengcindezi, engafaniswa futhi ihambisane nezinzwa ze-strain gauge.

3. Diffused silicon pressure sensor

Isimiso sokusebenza senzwa yengcindezi ye-diffused silicon sisekelwe futhi emthelela we-piezoresistive. Ngokusebenzisa umthetho womthelela we-piezoresistive, ingcindezi ye-medium ekaliwe isebenza ngokuqondile kwi-diaphragm yesinzwa (insimbi engagqwali noma i-ceramic), ukuze i-diaphragm ikhiqize ukuhamba okuncane okuhambelana nengcindezi ye-medium. Lokhu kwenza inani lokumelana kwenzwa lishintshe, kusetshenziswe isekethe ye-elekthronikhi ukuthola lolu shintsho, bese kuguqulwa futhi kukhishelwe isignali ejwayelekile yokulinganisa ehambisana nalengcindezi.

4. Piezoelectric pressure sensor

Umthelela we-piezoelectric uyisimiso esiyinhloko sokusebenza senzwa ye-piezoelectric. Inzwa ye-piezoelectric ayikwazi ukusetshenziselwa ukulinganisa okumile, ngoba i-charge emva kwamandla angaphandle igcinwa kuphela uma isekethe inokungangeneki okungenamkhawulo. Isimo sangempela akusona esinjalo, ngakho lokhu kunquma ukuthipiezoelectric pressure sensoringakwazi kuphela ukukala ingcindezi eguquguqukayo.
