Selelekela: Li-sensor tsa khatello ke lisebelisoa tsa bohlokoa tse sebelisoang haholo mafapheng a fapaneng a indasteri ho lekanya khatello ea likhase kapa lino. Leha ho le joalo, ho netefatsa ho nepahala le ho tšepahala ha liphetho tsa tekanyo, li-sensor tsa khatello li hloka ho lekanyetsoa kamehla. Sengoliloeng sena se tla hlahloba bohlokoa ba ho lekanya sensor ea khatello, mokhoa oa ho lekanya, le mekhoa e tloaelehileng ea ho lekanya.
Lebaka Leo ka Lona ho Hlokahalang ho Hlokahala: Ha nako e ntse e ea, li-sensor tsa khatello li ka 'na tsa e-ba le ho hoholeha kapa liphoso ka lebaka la maemo a tikoloho, ho apara 'meleng kapa mabaka a mang. Calibration ke mokhoa oa ho bapisa tlhahiso ea sensor ea khatello ho motho ea tsebahalang le ho etsa liphetoho tse hlokahalang ho felisa ho se lumellane hofe kapa hofe. Sena se tiisa hore sensor e fana ka litekanyo tse nepahetseng le tse tšepahalang.
Mokhoa oa Calibration:
- Boitokisetso: Pele ho lekanya, ho bohlokoa ho bokella lisebelisoa tse hlokahalang, ho kenyeletsoa mohloli oa khatello ea litšupiso, lisebelisoa tsa ho lekanya, le litekanyetso tse nepahetseng tsa ho lekanya. Etsa bonnete ba hore tikoloho ea calibration e tsitsitse ebile ha e na litšitiso leha e le life.
- Zero Calibration: Tekanyo ea zero e theha tlhahiso ea motheo ea sensor ea khatello ha ho sa sebelisoe khatello. Sensor e pepesetsoa khatello ea litšupiso ea zero mme e lokisoa ho netefatsa hore tlhahiso ea eona e lumellana le boleng bo lebelletsoeng ba zero.
- Tekanyo ea Span: Ho lekanya ha Span ho kenyelletsa ho sebelisa khatello e tsebahalang ea litšupiso ho sensor le ho lokisa tlhahiso ea eona hore e tsamaisane le boleng bo lebelletsoeng. Mohato ona o theha karabelo ea sensor le tatellano ho pholletsa le mefuta ea litekanyo.
- Tlhahlobo ea Lintlha: Ho pholletsa le ts'ebetso ea ho lekanya, data e bokelloa, ho kenyeletsoa ho baloa ha sensor ea sensor le litekanyetso tse lumellanang tsa litšupiso. Lintlha tsena lia hlahlojoa ho fumana ts'ebetso ea sensor le liphetoho tse hlokahalang.
Mekhoa e tloaelehileng ea ho lekanya:
- Deadweight Tester: Mokhoa ona o sebelisa litekanyo tse lekantsoeng ho sebelisa khatello e tsejoang ho sensor. Sephetho sa sensor se bapisoa le boleng bo lebelletsoeng, 'me liphetoho li etsoa ka nepo.
- Pressure Comparator: Mofani oa khatello o bapisa tlhahiso ea sensor ea khatello le khatello ea litšupiso e hlahisoang ke mohloli oa khatello e phahameng ea ho nepahala. Liphetoho leha e le life li lokisoa ka ho lokisa sensor.
- Reference Pressure Transducer: Mokhoa ona o kenyelletsa ho sebelisa transducer ea khatello ea maikutlo ka ho nepahala ho tsejoang ho lekanya khatello e sebelisoang ho sensor. Sephetho sa sensor se lokisoa hore se lumellane le 'malo oa transducer oa referense.
- Software Calibration: Li-sensor tse ling tsa khatello li fana ka calibration e thehiloeng ho software, moo liphetoho li ka etsoang ka mokhoa oa elektroniki ka li-algorithms tsa calibration. Mokhoa ona o lumella ho lekanya hantle le ho nepahala ntle le liphetoho tsa 'mele.
Melemo ea Calibration: Ho lekanya khafetsa ha li-sensor tsa khatello ho fana ka melemo e mengata:
- E netefatsa ho nepahala le ho ts'epahala ha lintlha tsa tekanyo.
- E eketsa ts'epo ts'ebetsong ea sensor mme e fokotsa ho se tsitse ha tekanyo.
- E thusa ho fihlela litlhoko tsa taolo le maemo a indasteri.
- E eketsa nako ea bophelo ea sensor ka ho tseba le ho lokisa mathata leha e le afe pele ho nako.
- E ntlafatsa ts'ebetso ea ts'ebetso le tlhahiso ka ho boloka litekanyo tse nepahetseng.
Qetello: Ho lekanya li-sensor tsa khatello ho bohlokoa bakeng sa ho netefatsa litekanyo tse nepahetseng le tse tšepahalang lits'ebetsong tse fapaneng tsa indasteri. Ka ho latela mokhoa o nepahetseng oa ho lekanya le ho sebelisa mekhoa e nepahetseng ea ho lekanya, ts'ebetso le nako e telele ea li-sensor tsa khatello li ka ntlafatsoa. Ho lekanya khafetsa ha ho matlafatse tekanyo ea tekanyo feela empa hape ho etsa hore batho ba tšepe boitsebiso bo fanoeng ke lisebelisoa tsena tsa bohlokoa.
