Inzwa yokucindezela uwoyela ye-Dodge Cummins Spare izingxenye zamafutha we-4921505

Indlela yokuxhumanisa sensor

I-wiring yezinzwa ibilokhu ingenye yemibuzo evame ukubonisana kakhulu kwinqubo yokuthenga yamakhasimende. Amakhasimende amaningi awazi ukuthi angazizwa kanjani izinzwa. Eqinisweni, izindlela ezinama-wiring zezinzwa ezahlukahlukene ngokufanayo ziyefana. Izinzwa zengcindezi ngokuvamile zinama-wire ezimbili, izintambo ezintathu, izintambo ezine nezinhlelo ezinhlanu ze-wire.

Uhlelo lwe-Wire-Wire lwe-Sensor yengcindezi lulula, futhi amakhasimende amaningi ayazi ukuthi angaxhuma kanjani izintambo. I-wire eyodwa ixhumeke kwisigxobo esihle sokuhlinzekwa kwamandla, nolunye ucingo, okungukuthi, ucingo lwesiginali, luxhumeke esigxotsheni esingesihle sokuphakelwa kwamandla ngokusebenzisa izinsimbi, okulula. Uhlelo lwe-Three-Wire lwe-Sensor Yengcindezelo lususelwa ohlelweni olunama-wire ezimbili, futhi lolu wire luxhumeke ngqo esigxotsheni esingesihle sokunikwa amandla, okunzima kakhulu kunohlelo olungama-wire. Inzwa yocingo enama-wire-wire kumele ibe okokufaka kwamandla amabili, kanti eminye emibili yimiphumela yesiginali. Iningi lohlelo lwe-wire-wire ezine yi-voltage okukhipha esikhundleni se-4 ~ 20ma okuphumayo, futhi i-4 ~ 20mA ibizwa ngengcindezelo transmitter, futhi iningi lazo lenziwa ngohlelo lwe-wire ezimbili. Eminye yemiphumela yesiginali yezinzwa zengcindezi ayikhuli, futhi umphumela ogcwele amashumi amancane ama-milivolts, kanti ezinye izinzwa zokucindezela zinemijikelezo yokumaka ngaphakathi, futhi okuphuma ngokuphelele kungu-0 ~ 2v. Ngokuqondene nokuthi ungaxhuma kanjani ithuluzi lokubonisa, kuya ngohlu lokulinganisa lwensimbi. Uma kukhona amagiya alungele isiginali yokuphuma, ingalinganiswa ngqo, ngaphandle kwalokho, isekethe yokulungiswa kwesiginali kufanele ingezwe. Kunomehluko omncane phakathi kwenzwa yengcindezi ye-wire-wire ne-wire gressure sensor, futhi kukhona izinzwa ezimbalwa zokucindezela ezinhlanu emakethe.

I-Pressure Sensor ingenye yezinzwa ezisetshenziswa kakhulu. Izinzwa zengcindezi yendabuko ikakhulukazi zibonisa amadivaysi emishini, akhombisa ingcindezi ngokuchazwa kwezinto ezinwebekile, kepha lesi sakhiwo sikhulu ngosayizi futhi sisinda ngesisindo, futhi asikwazi ukunikeza ukuphuma kukagesi. Ngokuthuthuka kobuchwepheshe be-semiconductor, izinzwa ze-semiconductor pressure zaqala ukuba khona. Kuboniswa ngevolumu encane, isisindo esikhanyayo, ukunemba okuphezulu nezici zokushisa ezinhle. Ikakhulu ngokuthuthukiswa kobuchwepheshe be-MEMS, izinzwa ze-semiconductor zithuthuka ngokubhekelwa okuncane ngokusetshenziswa kwamandla okuphansi kanye nokuthembela okuphezulu.
