Imingcele emine yezimboni yile:izinga lokushisa, ingcindezi, izinga lokugelezafuthiizinga loketshezi.
1. Izinga lokushisa
Izinga lokushisa liyinani elibonakalayo elimelela izinga lokubanda nokushisa kwento elinganisiwe. Ngokwendlela yokulinganisa yethuluzi lokushisa, lingahlukaniswa ngohlobo lokuxhumana nohlobo olungathintani. Imitha yokuxhumana yokulinganisa izinga lokushisa ihlanganisa ikakhulukazi i-thermometer, ukumelana nokushisa kanye ne-thermocouple. I-instrumenet yokulinganisa izinga lokushisa elingathintani ikakhulukazi i-optical pyrometer, i-photoelectric pyrometer, i-radiation pyrometer kanye ne-infrared thermometer.
2. Ingcindezi
Ingcindezi etholwa kunoma iyiphi into ihlanganisa ingcindezi yomoya kanye nengcindezi yendawo elinganisiwe (ngokuvamile ingcindezi yokulinganisa) izingxenye ezimbili, isamba sezingxenye ezimbili zengcindezi entweni elinganisiwe sibizwa ngokuthi ingcindezi ephelele, kanti i-industrial pressure gauge gauge ejwayelekile ilinganiswa ngenani le-gauge, okungukuthi, ithebula le-P =P eliphelele – ingcindezi yomoya.
Izinsimbi zokulinganisa ingcindezi zingahlukaniswa ngezigaba ezintathu: ngokuya ngamandla adonsela phansi kanye nendlela yokulinganisa ingcindezi elinganisiwe, kala ngqo usayizi wamandla endaweni yeyunithi, njengesilinganiso sokucindezela sekholomu yoketshezi kanye nesilinganiso sokucindezela kwepiston; Ngokwendlela yamandla e-elastic kanye nesilinganiso sokucindezela esilinganisiwe, kala amandla e-elastic akhiqizwa ukuguqulwa kwento e-elastic ngemva kokucindezelwa, njengesilinganiso sokucindezela kwentwasahlobo, i-bellows pressure gauge, i-diaphragm pressure gauge kanye ne-diaphragm box pressure gauge; Sebenzisa izakhiwo zomzimba zezinye izinto ezihlobene nengcindezi, njenge-voltage noma ukumelana noma izinguquko ze-capacitance lapho ucindezelwa; Isibonelo, izinzwa zokucindezela.
3. Ukugeleza
Ekukhiqizweni nasekulawuleni kwezimboni, ukutholwa nokulawulwa kwepharamitha yokugeleza koketshezi kungenye yezindlela ezivame kakhulu. Kunezinhlobo eziningi zamamitha asetshenziselwa ukukala ukugeleza, kufaka phakathi i-ultrasonic flowmeter, i-electromagnetic flowmeter, i-throttling flowmeter kanye ne-volumetric flowmeter.
4. Izinga
Izinga loketshezi libhekisela ezingeni lezinga loketshezi esitsheni esivaliwe noma esitsheni esivulekile. Amathuluzi asetshenziswa kakhulu ekulinganiseni izinga loketshezi yimitha yezinga le-ultrasonic, imitha yezinga lengilazi, imitha yezinga lokucindezela elihlukile, imitha yezinga lebhola elintantayo, imitha yezinga le-buoy, imitha yezinga le-magnetic flip plate yebhola elintantayo, imitha yezinga le-radar, imitha yezinga le-radioactive, imitha yezinga lokungena ngemvamisa yomsakazo, njll.
