Inzwa isetshenziselwa ukunquma ubukhulu: amandla adonsela phansi akhishwa isampula aguqulwa abe isignali kagesi ngenzwa yokukala. Ngakho-ke, iseli lomthwalo liyingxenye yesikali se-elekthronikhi.

Ubuchwepheshe obusetshenziswa kakhulu busekelwe kubuchwepheshe be-strain gauge: inzwa yesisindo se-analog iqukethe isici sokulinganisa (okuthiwa umzimba we-spring) owenziwe ngensimbi noma i-aluminium, lapho i-strain gauge (i-Wheatstone bridge) ifakwe khona. Isikali ngasinye se-elekthronikhi sineseli elihlanganisiwe lomthwalo ukuqinisekisa ukuthi isisindo singakalwa.

Izinzwa zokukala isisindo se-Strain gauge zisetshenziswa kabanzi, kodwa kunobunye ubuchwepheshe bokukala, obufana nobuchwepheshe besinxephezelo samandla kazibuthe kagesi i-EMFC, okunqunywa kwayo ngobuningi kwenziwa ngokuphelele ngaphandle kokulahlekelwa ukungqubuzana. Ngokuvamile, amaseli omthwalo afakwe emafektri, njengokugcwalisa izitshalo, amathangi okukala, ukunquma inani lokugcwalisa, njll.

I-Sensor wiring ibilokhu ingomunye wemibuzo okuxoxwe ngayo kakhulu kwinqubo yokuthengwa kwekhasimende, amakhasimende amaningi awazi ukuthi angaxhuma kanjani inzwa, empeleni, izindlela zokufaka izintambo zezinzwa ezihlukahlukene ziyafana ngokuyisisekelo, izinzwa zokucindezela ngokuvamile zinesistimu yocingo ezimbili, isistimu yezintambo ezintathu, isistimu yezintambo ezine, kanye nesistimu yezintambo ezinhlanu.
Uhlelo lwe-pressure sensor lwezintambo ezimbili lulula, amakhasimende ajwayelekile ayakwazi ukufaka izintambo, intambo ixhunywe kugesi omuhle, omunye umugqa wesignali ngokusebenzisa ithuluzi elixhunywe kugesi ongemuhle, lokhu kulula kakhulu, inzwa yokucindezela uhlelo lwezintambo ezintathu lusekelwe ohlelweni lwezintambo ezimbili kanye nomugqa, umugqa uxhunywe ngokuqondile kumandla angalungile, izinkinga ezingaphezu kwesistimu yezintambo ezimbili. Inzwa yokucindezela enezintambo ezine nakanjani iwukufakwa kwamandla okubili, kanti okunye okubili okuphumayo kwesignali. Isistimu enezintambo ezine ngokuvamile iphuma ku-voltage kunokukhipha okungu-4~20mA, i-4~20mA ebizwa ngokuthi i-pressure transmitter, iningi lenziwe ngesistimu yezintambo ezimbili. Okunye okukhipha isignali yenzwa yokucindezela akukhuliswanga, futhi okukhiphayo kwesikali esigcwele kungamashumi amamilivolthi kuphela, kuyilapho ezinye izinzwa zokucindezela zinesekhethi ye-amplifier ngaphakathi, nokuphuma kwesikali esigcwele ngu-0~2V. Ngokuqondene nendlela yokwamukela ithuluzi lokubonisa, kuya ngokuthi ububanzi bensimbi bukhulu kangakanani, uma kukhona igiya elihambisana nesiginali yokuphumayo, lingalinganiswa ngokuqondile, ngaphandle kwalokho kuyadingeka ukwengeza isifunda sokulungisa isignali. . Inzwa yokucindezela kwezintambo ezinhlanu ayihlukile kakhulu ohlelweni lwezintambo ezine, futhi inzwa enezintambo ezinhlanu emakethe imbalwa uma kuqhathaniswa.
