Iiparamitha ezine zoshishino zeziubushushu, uxinzelelo, umgangatho wohambokwayeinqanaba lolwelo.
1. Ubushushu
Ubushushu lixabiso elibonakalayo elimele inqanaba lokubanda kunye nobushushu bento elinganisiweyo. Ngokwendlela yokulinganisa yesixhobo sobushushu, inokwahlulwa ibe luhlobo loqhagamshelwano kunye nohlobo olungadibaniyo. Imitha yoqhagamshelwano yokulinganisa ubushushu ibandakanya ikakhulu i-thermometer, ukumelana nobushushu kunye ne-thermocouple. Isixhobo sokulinganisa ubushushu esingadibaniyo ikakhulu yi-optical pyrometer, i-photoelectric pyrometer, i-radiation pyrometer kunye ne-infrared thermometer.
2. Uxinzelelo
Uxinzelelo olufunyanwa kuyo nayiphi na into luquka uxinzelelo lomoya kunye noxinzelelo lwesixhobo esilinganisiweyo (ngokubanzi uxinzelelo lokulinganisa) iinxalenye ezimbini, isimbuku samacandelo amabini oxinzelelo kwinto elinganisiweyo sibizwa ngokuba luxinzelelo olupheleleyo, kwaye i-ordinal industrial pressure gauge ilinganiswa ngexabiso lokulinganisa, oko kukuthi, i-P table =P absolute – uxinzelelo lomoya.
Izixhobo zokulinganisa uxinzelelo zinokwahlulwahlulwa zibe ziindidi ezintathu: ngokwegravithi kunye nendlela yokulinganisa uxinzelelo olulinganisiweyo, linganisa ngokuthe ngqo ubungakanani bamandla kwindawo yeyunithi, njenge-liquid column pressure gauge kunye ne-piston pressure gauge; Ngokwendlela yamandla e-elastic kunye ne-metal pressure balance, linganisa amandla e-elastic aveliswa kukuguqulwa kwe-elastic element emva koxinzelelo, njenge-spring pressure gauge, i-bellows pressure gauge, i-diaphragm pressure gauge kunye ne-diaphragm box pressure gauge; Sebenzisa iipropati zomzimba zezinye izinto ezinxulumene noxinzelelo, ezifana ne-voltage okanye ukumelana okanye utshintsho lwe-capacitance xa ucinezelwe; Umzekelo, ii-sensors zoxinzelelo.
3. Ukuhamba
Kwimveliso nolawulo lwemizi-mveliso, ukufunyanwa nokulawulwa kweparameter yokuhamba kolwelo yenye yezona parameter zixhaphakileyo. Kukho iintlobo ezininzi zeemitha ezisetyenziselwa ukulinganisa ukuhamba, kuquka i-ultrasonic flowmeter, i-electromagnetic flowmeter, i-throttling flowmeter kunye ne-volumetric flowmeter.
4. Inqanaba
Inqanaba lolwelo libhekisa kwinqanaba lolwelo kwisikhongozeli esivaliweyo okanye kwisikhongozeli esivulekileyo. Izixhobo ezisetyenziswa rhoqo ukulinganisa inqanaba lolwelo yimitha yenqanaba le-ultrasonic, imitha yenqanaba leglasi, imitha yenqanaba loxinzelelo oluhlukeneyo, imitha yenqanaba lebhola elintantayo, imitha yenqanaba le-buoy, imitha yenqanaba le-magnetic flip plate yebhola elintantayo, imitha yenqanaba le-radar, imitha yenqanaba le-radioactive, imitha yenqanaba lokungena kwi-radio frequency, njl.njl.
