Inzwa yokucindezela kawoyela ye-Dodge Cummins izingxenye ezisele zikaphethiloli injini 4921505

Indlela yokuxhuma inzwa

Ukufakwa kwezintambo kwezinzwa bekulokhu kungomunye wemibuzo okukhulunywa ngayo kakhulu ohlelweni lokuthenga kwamakhasimende. Amakhasimende amaningi awazi ukuthi zifakwa kanjani izinzwa ngocingo. Eqinisweni, izindlela zokufaka izintambo zezinzwa ezihlukahlukene ngokuyisisekelo ziyefana. Izinzwa zokucindezela ngokuvamile zinezintambo ezimbili, izintambo ezintathu, izintambo ezine kanye nezinye izinhlelo ezinezintambo ezinhlanu.

Uhlelo lwezintambo ezimbili lwenzwa yokucindezela lulula, futhi amakhasimende amaningi ayazi ukuxhuma izintambo. Intambo eyodwa ixhunywe endaweni ephozithivu yokuphakelwa kwamandla, kanti enye intambo, okungukuthi, intambo yesiginali, ixhunywe esigxotsheni esinegethivu sokuphakelwa kwamandla ngokusebenzisa amathuluzi, okulula kakhulu. Isistimu yezintambo ezintathu zenzwa yokucindezela isekelwe ohlelweni lwezintambo ezimbili, futhi lolu cingo luxhunywe ngokuqondile esigxotsheni esibi sokunikezwa kwamandla, okuyinkinga kancane kunesistimu yezintambo ezimbili. Inzwa yokucindezela kwezintambo ezine kufanele kube okokufaka kwamandla okubili, kanti okunye okubili okuphumayo kwesignali. Iningi lesistimu enezintambo ezine i-voltage ephumayo esikhundleni sokuphuma kwe-4~20mA, futhi i-4~20mA ibizwa ngokuthi i-pressure transmitter, futhi iningi lazo lenziwa ohlelweni lwezintambo ezimbili. Eminye yemiphumela yesignali yezinzwa zengcindezi ayikhuliswanga, futhi okukhiphayo kwesikali esigcwele kungamashumi kuphela amamilivolthi, kuyilapho ezinye izinzwa zokucindezela zinamasekhethi okukhulisa ngaphakathi, futhi okukhiphayo kwesikali esigcwele kungu-0~2V. Ngokuqondene nendlela yokuxhuma ithuluzi lokubonisa, kuya ngebanga lokulinganisa lensimbi. Uma kukhona igiya elifanele isignali yokuphumayo, lingalinganiswa ngokuqondile, ngaphandle kwalokho, umjikelezo wokulungisa isignali kufanele wengezwe. Kunomehluko omncane phakathi kwenzwa yokucindezela kwezintambo ezinhlanu kanye nenzwa yokucindezela kwezintambo ezine, futhi kunezinzwa zokucindezela ezinezintambo ezinhlanu ezimbalwa emakethe.

Inzwa yokucindezela ingenye yezinzwa ezisetshenziswa kakhulu. Izinzwa zokucindezela zendabuko ikakhulukazi ziyimishini yemishini, ekhombisa ingcindezi ngokuwohloka kwezinto ezinwebekayo, kodwa lesi sakhiwo sikhulu ngosayizi nesisindo esinzima, futhi asikwazi ukuhlinzeka ngokukhipha ugesi. Ngokuthuthuka kobuchwepheshe be-semiconductor, izinzwa zokucindezela kwe-semiconductor zaba khona. Ibonakala ngevolumu encane, isisindo esincane, ukunemba okuphezulu kanye nezici ezinhle zokushisa. Ikakhulukazi ngokuthuthukiswa kobuchwepheshe be-MEMS, izinzwa ze-semiconductor zithuthukela ku-miniaturization ngokusebenzisa amandla aphansi kanye nokuthembeka okuphezulu.
