Tej zaum koj yuav txaus siab rau
Qhov "wide range" txhais li cas tiag? Nws tus nqi npaum li cas rau - cov haujlwm loj?
Qhov dav dav hais txog lub ntsuas dej uas tswj tau qhov tseeb ntawm qhov dav dav (feem ntau R250 / R400 thiab siab dua).
Nws tus nqi rau loj - cov haujlwm ntim nyob hauv:
Tsis nco qab nyeem ntawm tus nqi qis (kev siv dej me me thaum hmo ntuj, poob dej)
Tsis muaj kev cuam tshuam ntawm cov dej ntws siab (kev siv dej siab, kev siv dej hauv nruab nrab)
Txo cov kev tsis txaus siab thiab ntsuas kev tsis sib haum xeeb, txo qis kev pheej hmoo ua haujlwm
Ib qho qauv sib koom ua ke npog ntau yam kev ua haujlwm, ua kom yooj yim rau kev yuav khoom thiab tswj cov khoom muag.
ruaj khov thiab ntev npaum li cas -lub sij hawm yog ultrasonic dej ntsuas hauv loj- teev, ntev - siv sijhawm?
Ultrasonic dej ntsuas tsis muaj cov khoom siv txav mus los thiab yog li tsis muaj teeb meem hnav, ua rau lawv tshwj xeeb tshaj yog haum rau ntev -lub sij hawm, loj- nplai installation.
Qhov zoo muaj xws li:
Muaj zog tiv thaiv dej impurities, tsis yooj yim rau jamming
Ntev - lub sij hawm ruaj khov metering nrog tsawg qhov tseeb degradation
Hom tsim lub neej ntawm 10-15 xyoo lossis ntau dua
Haum rau siab - zaus nyeem ntawv ntsuas dej thiab kev tswj xyuas dej ntse.
Yuav ua li cas kom ntseeg tau cov khoom sib xws thiab kev tswj kom zoo thaum lub sijhawm loj - ntim khoom?
Rau ntau qhov project, peb feem ntau muab:
Tag nrho- txheej txheem calibration thiab kuaj Hoobkas (unit-los ntawm-unit lossis random sampling)
Ua raws li cov qauv thoob ntiaj teb xws li ISO 4064 / MID / OIML R49
Batch traceability (SN / ntau lawm cov ntaub ntawv / calibration data)
Kev them nyiaj yug rau thib peb -kev xeem cov tog neeg los yog qhov yuav tsum tau ua piv txwv
Ua kom muaj kev ua tau zoo ib yam thiab cov ntaub ntawv txhim khu kev qha rau txhua pawg ntawm cov ntsuas dej hauv tib qhov project.
