Qhov qis tshaj qhov tseeb ntawm qhov ntsuas siab yog 4.
Lub ntsuas ntsuas siab rau kev siv dav hauv Suav teb tau muab faib ua plaub qib raug, uas yog nyob rau hauv txoj kab nrog kev tso cai yuam kev ntawm cov ntsuas ntsuas siab tau teev tseg hauv cov ntawv pov thawj JJG52-1999" General Pressure Gauges nrog Lub Caij Nplooj Ntoos Hlav, Siab thiab Vacuum Gauges and Vacuum Gauges".
Plaub theem qhov tseeb yog: qib 1, qib 1.6, qib 2.5 thiab qib 4.Qhov kev tso cai yuam kev (raws li feem pua ntawm cov kev txwv siab tshaj ntawm kev ntsuas) yog ± 1%, ± 1.6%, ± 2.5%, ± 4%, feem.
Cov ntaub ntawv ntxiv:
Upper limit of pressure gauge:
Qhov loj ntawm qhov txwv siab ntawm lub ntsuas siab yog tsim raws li qhov loj me, nruj thiab nonlinear tej yam kev mob ntawm lub caij nplooj ntoos hlav raj. Cov kev txwv sab saud ntawm kev ntsuas yog 1 × 10N, 1.6 × 10N, 2.5 × 10N, 4 × 10N, 6 × 10N tsib series, n yog tus lej zoo, tus lej tsis zoo lossis xoom.
