Mawu Oyamba
4-20 mA Vibration Monitoring Njira Yathaview
Ukadaulo wa 4-20 mA ungagwiritsidwe ntchito kuyeza kutentha, kuthamanga, kuyenda ndi liwiro, komanso kugwedezeka kwathunthu kwa makina ozungulira. Kuwonjezera sensor / transmitter yogwedezeka pamakina kumapereka muyeso wofunikira wamakina. Itha kugwiritsidwa ntchito kuzindikira kusintha kwa kusanja, kusanja, magiya, mayendedwe, ndi zolakwika zina zambiri. Cholinga cha 4-20 mA analogi panopa kuzungulira ndi kufalitsa chizindikiro kuchokera analogi kugwedera sensa pa mtunda mu mawonekedwe a 4-20 mA chizindikiro panopa. Chizindikiro chamakono chomwe chimapangidwa ndi chofanana ndi kugwedezeka kwathunthu kwa zida kapena makina omwe akuyang'aniridwa. Kutulutsa kumeneku kumakhala ndi 4-20 mA, ndi 4 kuyimira zochepa ndi 20 kuyimira pazipita. ampmphamvu (pakati pa 4-20 mA). Kutulutsa kwa 4-20 mA ndikofanana ndi chonse amplitude yopangidwa mkati mwa band yodziwika. Choncho, chizindikirocho sichimaphatikizapo deta kuchokera kufupipafupi kunja kwa ma frequency band koma imaphatikizapo kugwedezeka konse (zolakwa zazikulu ndi zosafunikira) mkati mwa gululo.

Wiring
The Intrinsic Safety Control Drawing INS10012 pansipa ikuwonetsa zofunikira pakuyika kwa CTC IS Sensors. Monga momwe zasonyezedwera, zotchinga zoyikidwa bwino zimafunikira kuchepetsa mphamvu yomwe sensor ingalandire. Cabling imabweretsa chizindikiro kuchokera ku sensa kupita ku Zener diode chotchinga kapena galvanic isolator, yomwe ndi mawonekedwe ochepetsa mphamvu. Chizindikirocho chimasamutsidwa kudzera pa chotchinga (chomwe chikhoza kukhala mu Class I Div 2 kapena malo osakhala owopsa) kupita ku zipangizo zoyezera, monga zosonkhanitsa deta kapena bokosi lophatikizirapo, kuti zitheke.

Kuyika
Dzanja limbani sensa ku disk yokwera ndikumangitsa pogwiritsa ntchito 2 mpaka 5 ft-lbs ya mphamvu yokwezera.
- Ma torque okwera ndikofunikira pakuyankha pafupipafupi kwa sensor pazifukwa izi:
- Ngati sensayo siili yolimba mokwanira, kugwirizanitsa koyenera pakati pa maziko a sensa ndi disk yokwera sikungapindule.
- Ngati sensa yatha, kulephera kwa stud kumatha kuchitika.
- Cholumikizira (monga MH109-3D epoxy) chidzakulitsa kuyankha pafupipafupi kwa hardware yanu, koma sikofunikira.
Kukonzekera Kwamuyaya / Stud Mounting Surface
- Konzani malo athyathyathya pogwiritsa ntchito chida chakumaso komanso bowo lobowola woyendetsa pogwiritsa ntchito chida choyikira nkhope ndi malo a CTC.
- Malo okwera ayenera kukhala oyera komanso opanda zotsalira kapena utoto.
- Dinani pa ulusi wofunikira ( ¼-28 kapena M6x1).
- Ikani sensa.

Chitsimikizo ndi Kubwezeredwa
Chitsimikizo
Zogulitsa zonse za CTC zimathandizidwa ndi chitsimikizo chathu chopanda malire. Ngati mankhwala aliwonse a CTC alephera, tidzakonza kapena kuwasintha popanda malipiro.
Kubweza ndalama
Zogulitsa zonse zitha kubwezeredwa ndi chindapusa cha 25% ngati chibwezeredwa mumkhalidwe watsopano mkati mwa masiku 90 atatumizidwa. Zogulitsa zamsika zimakhala zoyenera kuthetsedwa kwaulere ngati oda yanu yathetsedwa mkati mwa maola 24 mutagula. Zogulitsa zomangidwa kuti ziwomboledwe zimayenera kubwezeredwa 50% ngati zibwezedwa mumkhalidwe watsopano mkati mwa masiku 90 atatumizidwa. Zogulitsa zamakasitomala zimatchulidwa ndikumangidwira zomwe makasitomala amafuna, zomwe zingaphatikizepo mapangidwe amtundu wazinthu kapena mitundu yodziwika bwino yamakasitomala a OEM. Zogulitsa zomwe zayitanitsa ndizosaletsa, sizibwezedwa komanso sizingabwezedwe.
