Iko kurongeka kwegeji yekumanikidza kunonyanya kuratidzwa negiredhi rayo rechokwadi.
Iko kurongeka kwegiredhi ndiyo yakakosha parameter ye pressure gauge, ichiratidza huchokwadi hwechiyero chemhedzisiro yayo. Kazhinji, giredhi rechokwadi rinomiririrwa nenhamba, senge 1.0, 1.6, kana 2.5. Iyi nhamba inomiririra kukanganisa kukuru kunotenderwa kwechiyero chepressure sechikamu chechiyero chekuyeresa kwayo.
Semuenzaniso, kana Class 1.0 pressure gauge ine huwandu hwe 0-10 MPa, kukanganisa kwayo kukuru kunotenderwa ndeye (10 MPa) yakapetwa nezana rinoenderana negiredhi yechokwadi (1.0%), inova 0.1 MPa. Izvi zvinoreva kuti pamusoro peyero yese yekuyeresa, kuyerwa kwekuyerwa kweiyo geji yekumanikidza haipfuure ± 0.1 MPa.
Iko kurongeka kwegiredhi yekumanikidza gauge inotarwa panguva yekugadzira kwayo uye maitiro ekugadzira. Zvinonyanya kuenderana nezvakawanda zvinhu, kusanganisira chimiro chegeji, hunhu hweiyo elastic element, iko kurongeka kweiyo nzira yekufambisa, uye maitiro ekugadzira. Marefu-mageji ekudzvanya anowanzo shandisa zvinhu zvinorembera, zvakaita semachubhu eBourdon akagadzirwa nema alloys akakosha. Zvinhu izvi zvinopa zvakagadzikana uye zvakanyatsoita elastic zvimiro, uye nzira yekufambisa inogadzirwa uye inogadzirwa nehupamhi hwepamusoro, nekudaro ichideredza kuyerwa kukanganisa.
Iyo yechokwadi nhanho inowanzo ratidzwa pane yekumanikidza geji dial, ingave pane nameplate kana mune yakabatana yekumaka nzvimbo. Izvi zvinobvumira vashandisi kuti vaongorore kuvimbika kwekumanikidzika kuverenga kunobva pachiyero chekururama. Semuyenzaniso, maapplication anoda high{2}}precision pressure measurement, sezviyedzo zvesainzi uye high-precision industrial process control control, inoda mapresent gauges ane mwero wepamusoro kuti ive nechokwadi chekuyera data.
Uyezve, kurongeka kwegauji yekumanikidza kunogona kukanganiswa nemamiriro ekushanda. Semuenzaniso, kuchinja kwekushisa kunogona kukonzera elastic modulus ye elastic element kuchinja, zvichikanganisa kuyerwa kwechiyero. Naizvozvo, mumashandisirwo anoda kurongeka kwakanyanya, zvinodikanwa kufunga nezvemuripo wetembiricha uye mamwe matanho kuchengetedza kurongeka kwegeji yekumanikidza.
