I-pressure switch 97137042 ifanele inzwa yokucindezela ye-Isuzu

1. Ukunemba

Ukunemba kuyinkomba yokusebenza ebalulekile yenzwa, okuyisixhumanisi esibalulekile esihlobene nokunemba kokulinganisa kwalo lonke uhlelo lokulinganisa.Ukuphakama kokunemba kwenzwa, kuyabiza kakhulu.Ngakho-ke, ukunemba kwenzwa kudinga kuphela ukuhlangabezana nezidingo zokunemba zalo lonke uhlelo lokulinganisa, futhi akudingekile ukukhetha phezulu kakhulu.Ngale ndlela, singakhetha inzwa eshibhile futhi elula phakathi kwezinzwa eziningi ezihlangabezana nenhloso yokulinganisa efanayo.

Uma inhloso yokulinganisa kuwukuhlaziya kwekhwalithi, izinzwa ezinokunemba kokuphindaphinda okuphezulu kufanele zikhethwe, kodwa lezo ezinokunemba kwenani eliphelele eliphezulu akufanele zikhethwe;Uma kungokuhlaziywa kobuningi, kuyadingeka ukuthola amanani okulinganisa anembile, ngakho-ke kuyadingeka ukukhetha izinzwa ezinamaleveli okunemba agculisayo.

Kwezinye izinhlelo zokusebenza ezikhethekile, uma kungenakwenzeka ukukhetha inzwa efanelekile, sidinga ukuklama nokukhiqiza inzwa ngokwethu.Ukusebenza kwenzwa yokuzenzela kufanele kuhlangabezane nezidingo zokusebenzisa.

2.Umusa

Kunezinhlobo eziningi zezinzwa zemishini, njengenzwa yokucindezela kwe-resistance gauge, inzwa yokucindezela kwe-semiconductor strain gauge, inzwa ye-piezoresistive pressure, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor kanye ne-capacitive acceleration sensor.Kodwa esetshenziswa kakhulu inzwa yokucindezela kwe-piezoresistive, enenani eliphansi kakhulu, ukunemba okuphezulu kanye nezici ezinhle zomugqa.

3.Yazi

Uma sinciphisa inzwa yokucindezela kokumelana, siqala sazi igeji yohlobo lokumelana.I-Resistance strain gauge iwuhlobo lwedivayisi ebucayi eguqula ushintsho lwestrain engxenyeni elinganisiwe ibe isignali kagesi.Ingenye yezingxenye eziyinhloko ze-piezoresistive strain sensor.Izikali ze-Metal resistance gauge kanye nama-semiconductor strain gauge asetshenziswa kakhulu.Kunezinhlobo ezimbili zamageji ohlobo lwensimbi okumelana nezinsimbi: amageji ohlobo lwezintambo namageji ohlobo lwensimbi.Ngokuvamile, i-strain gauge iboshelwe ngokuqinile ku-substrate ekhiqiza ubunzima bemishini nge-adhesive ekhethekile.Lapho ukucindezeleka kwe-substrate kushintsha, ukumelana kwe-gauge yobunzima kuyashintsha, ukuze i-voltage esetshenziswe ku-resistor ishintshe.Ngokuvamile, lolu hlobo lwegeji yohlobo lunoshintsho oluncane lokumelana lapho lucindezelwa.Ngokuvamile, lolu hlobo lwegeji yohlobo lwakha ibhuloho lobunzima, elikhuliswa isikhulisi sensimbi esilandelayo bese lidluliselwa kumjikelezo wokucubungula (ngokuvamile ukuguqulwa kwe-A/D ne-CPU) ukuze kuboniswe noma kusetshenziswe.
