I-Pressure Sensor uhlobo lwezinzwa zengcindezi ezingasetshenziswa kumakhemikhali ensimbi, amakhemikhali nakwezinye izindlela ukukala ingcindezi, futhi ungabona ukulawulwa kwengcindezi okuzenzakalelayo lapho kusetshenziswa kanye noMlawuli Wengcindezi.
I-Diffusion Silicon Psressure Sensor / Isingeniso Sethulelo
I-Diffusion Silicon Psressure Sensor isuselwa kumgomo we-PieZoresurive Effect, usebenzisa ubuchwepheshe obuhlanganisiwe wenqubo ngokusebenzisana nokuvinjwa kwezimpawu ze-silicon ezisetshenziswayo ze-silicon. Ukuhlanganisa ukuhlanganisa izinzwa nokutholwa kukagesi ngogesi kwenziwa.
Ingcindezi yenzwa ye-silicon ye-silicon esebenza ngqo kwi-diaphragm yenzwa (insimbi engagqwali noma i-ceramic), okwenza i-diaphragm ikhiqize ngokulingana okulingana nengcindezi ye-medium, kanye nenani lokumelana lezinzwa lishintsha. Umjikelezo we-elekthronikhi ubona lolu shintsho futhi aluguqule. Isiginali ejwayelekile yokulinganisa ehambelana nale ngcindezi ikhishwa.
Izici ze-Diffusion Silicon Pressure Sensor
1. Ilungele ukwenza ama-transmitters amancane
Umphumela we-PieZoresoresive womphikisi ozwelayo we-arf
2. Ukuzwela okuphezulu okuphezulu
Isici sokuzwela sokumelana se-silicon siphakeme ka-50 kuya ku-100 kunesilinganiso se-metal gauge, ngakho-ke ukuzwela kwenzwa ehambisanayo kuphezulu kakhulu, kanti ukuzwela okuhambisanayo kuphezulu kakhulu, kanti ukuvela okujwayelekile kungama-100mv. Ngakho-ke, azikho izidingo ezikhethekile zokwakheka kwesikhombimsebenzisi, futhi kulula kakhulu ukuyisebenzisa.
3. Ukunemba okuphezulu
Kusukela ukuguqulwa okuzwakalayo, ukuguqulwa okubucayi kanye nokutholwa kwenzwa kutholwa yingxenye efanayo, asikho isixhumanisi sokuguqula esiphakathi, kanye namaphutha wokuphindaphinda futhi amaphutha aphindwayo mancane. Njengoba i-selicon ye-monocrystalline ngokwayo inobunzima obukhulu nokuguqulwa okuncane, ukuqonda okuhle kuyaqinisekiswa.
4. Njengoba ukuguquguquka okungathandeki komsebenzi kuphansi njengokuhleleka kwe-micro-strain, ukufuduka okuphezulu kwe-chip ebanzi kungokuhleleka kwe-micron-micron, ngakho-ke akukho mjikelezo, futhi i-span yokuphila isikhathi eside, futhi nokusebenza okuzinzile kanye nokuthembela okuqinile.

6. Njengoba i-chip yamukele inqubo ehlanganisiwe futhi ayinazo izingxenye zokuhambisa, incane ngosayizi nokukhanya kwesisindo.
I-Diffusion Silicon Psressure Sensor Sensors yokusebenzisa
1.Kwathi kukhethwe ibanga eliphakeme kakhulu noma ibanga elingaphansi kwamazinga angaphansi, amplitude kufanele lilawulwe ngaphakathi kwama-30 ama-30% FS.
2.Imodi yokucindezela ihlukaniswe ngengcindezi yegeji, ingcindezi ngokuphelele kanye nengcindezi yokubopha uphawu, okungakhethwa ngokunengqondo ngokwezidingo.
3.Kuqinisekisa ukugcwala ngokweqile kohlelo. Ukugcwala ngokweqile kohlelo kufanele kube ngaphansi komkhawulo wokuvikelwa okulayishwe ngokweqile, uma kungenjalo kuzothinta impilo yenkonzo yomkhiqizo futhi kulimaze umkhiqizo.
I-4.Angathinti idaphragm nganoma yiziphi izinto ezinzima, uma kungenjalo kuzodala ukuqhekeka.
5.Izinto ezibonakalayo kanye nenqubo yokwenza ingcindezi engemihle ayifani nengcindezi enhle, ngakho-ke ingcindezi engemihle ayikwazi ukushintshwa yi-gauge ingcindezi eyisisekelo.
6.Sicela uhlole incwadi yokufundisa ngokucophelela ngaphambi kokufaka ukugwema ukulimala komkhiqizo okubangelwa ukufakwa okungalungile.
I-7propeoper Ukusetshenziswa kungaholela engcupheni nasekulimaleni komuntu.
8.Umgogodla ukhishwe ezindlini, futhi kwenqatshelwe ukudonsa izintambo nemilenze yeshubhu.
Izicelo ze-Diffusion Silicon Pressure Sensor
Izinzwa ze-Difsion Silicon Pssupres zisetshenziswa ikakhulukazi ezinhlelweni zokulawula inqubo, amathuluzi wokulinganisa wengcindezi, amasistimu we-hydraulic, amathuluzi we-hydraical, ukulinganisa kwe-hvac, imishini yokulawula i-HVAC kanye nezimboni ze-HVAC zokulawula. Kungashiwo ukuthi zonke izimboni ezinezidingo eziphakeme ze-automation, zingasebenzisa izinzwa ze-Silicon Pressure.
