Ma sensor a kuthamanga nthawi zambiri amagawidwa m'magawo ndi kufotokozedwa ndi magawo angapo. Kumvetsetsa mwachangu zofunikira zoyambira kungathandize kwambiri pakupeza kapena kusankha sensor yoyenera. Tiyenera kudziwa kuti zofunikira za Instrumentations zitha kusiyana pakati pa opanga kapena kutengera mitundu ya sensor yomwe imagwiritsidwa ntchito.
★ Mtundu wa kupanikizika - mtundu wa kupanikizika komwe sensa yapangidwira kuti igwire ntchito. Zosankha zodziwika nthawi zambiri zimaphatikizapo gauge, absolute, sealed, vacuum, negative ndi differential pressure.
★ Kuthamanga kwa ntchito - kuchuluka kwa kuyeza kuthamanga kwa ntchito kwa bolodi la circuit kuti lipange chizindikiro chofanana.
★ Kupanikizika kwakukulu - ndiye kuti chipangizocho chingathe kugwira ntchito bwino popanda kuwononga chipangizo cha sensor. Kupitirira malire kungayambitse vuto losasinthika la zida kapena kuwonongeka kwa kulondola.
★ Sikelo yonse - kutalika kuyambira pa zero kupanikizika mpaka ku mphamvu yayikulu yoyezera.
★ Mtundu wa zotulutsa - Mtundu ndi kuchuluka kwa zotulutsa za chizindikiro, nthawi zambiri zimakhala milliampere kapena voltage. Njira zolumikizirana mwanzeru monga HART ndi RS-485 zikukhala zodziwika bwino.
★ Mphamvu yamagetsi - Mphamvu yamagetsi yopatsa mphamvu chida choyimiridwa ndi mphamvu yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi yokhazikika kapena yovomerezeka. Mwachitsanzo 24VDC (12 ~ 36V).
★ Kulondola - kusiyana pakati pa kuwerenga ndi kupanikizika kwenikweni komwe kumaimiridwa ndi kuchuluka kwa sikelo yonse. Kuwerengera kwa fakitale ndi kubwezera kutentha kungathandize kuyesa ndikuwongolera kulondola kwa chipangizocho.
★ Kusasinthika - kusiyana kochepa kwambiri komwe kungaonekere mu chizindikiro chotulutsa.
★ Kukhazikika - kusuntha pang'onopang'ono pakapita nthawi mu mkhalidwe wolinganizidwa wa chotumizira.
★ Kutentha kogwirira ntchito – kutentha kwa chipangizocho komwe chipangizocho chapangidwira kuti chigwire ntchito bwino ndikutulutsa ziwerengero zodalirika. Kugwira ntchito nthawi zonse ndi kutentha kopitirira malire a kutentha kungawononge kwambiri gawo lonyowa.
Shanghai WangYuan Instruments of Measurement Co., Ltd. ndi kampani yaku China yaukadaulo wapamwamba yomwe yakhala ikuyang'anira ukadaulo ndi zinthu zowongolera njira zamafakitale kwa zaka zoposa makumi awiri. Tikhoza kupereka zonsemizere yazinthuya ma transmitter opanikizika malinga ndi zomwe makasitomala akufuna pa magawo omwe ali pamwambapa.
