Nā Pōmaikaʻi o nā Mīkini Pae Ultrasonic

ʻO nā mika pae Ultrasonic he mau mea ana pae wai ʻaʻole e pili ana i ke kumumanaʻo ultrasonic ranging. Me nā hiʻohiʻona noi ākea, ka hoʻonohonoho maʻalahi a me ka mālama ʻana, hoʻohana nui ʻia lākou i nā ʻoihana, ka mālama wai, ka ʻenekinia kemika a me nā ʻoihana ʻē aʻe. ʻO kā lākou mau pono nui penei:

1. Ana ʻole pili me ka palekana kiʻekiʻe a ʻaʻohe ʻaʻahu

ʻAʻole pili pololei ka probe sensor me ka medium i ana ʻia, e pale ana i ka pala, ka ʻānai ʻana, ka hoʻopili ʻana a i ʻole ka haumia i hoʻokumu ʻia e ka medium. He kūpono loa ia no ke ana ʻana i nā media weliweli a i ʻole corrosive e like me nā waikawa ikaika, nā alkalis ikaika, ka viscosity kiʻekiʻe, nā mea crystallizable a me nā mea volatile. I kēia manawa, pale ia i ka haumia o nā media maʻemaʻe i ka meaʻai, nā lāʻau lapaʻau a me nā ʻoihana ʻē aʻe. Eia kekahi, ʻaʻohe ʻaʻahu mechanical o ka probe, e hōʻoiaʻiʻo ana i ka lōʻihi o ke ola lawelawe.

2. Hoʻonohonoho maʻalahi a me ka hiki ke hoʻololi ikaika

Kākoʻo ia i nā ʻano hoʻonohonoho maʻalahi e like me ke kau ʻana ma luna a me ke kau ʻana ma ka paia ʻaoʻao, e hoʻopau ana i ka pono no ka hoʻololi ʻana i ke ʻano o ka pahu a i ʻole ke kūkulu hou ʻana i ka paipu paʻakikī. Hoʻemi nui kēia i ka manawa kūkulu a me nā kumukūʻai. Loaʻa iā ia nā koi palupalu no nā wahi hoʻonohonoho, e kūʻē ana i nā loli nui i ka mahana waena (pae maʻamau: -40℃~150℃) a me ke kaomi (kaomi lewa a i ʻole kaomi waena-haʻahaʻa), a hoʻololi i nā kūlana hana paʻakikī e like me ka lepo a me ka noe.

3. Ka laulā ana ākea a me ka pololei paʻa

Uhi ia i kahi laulā ana ākea, mai ka liʻiliʻi o 3m a i ka nui o 40m, e hoʻokō ana i nā pono ana o ka pae wai o nā pahu a me nā loko wai like ʻole. ʻAʻole i hoʻopilikia nui ʻia kona pololei ana e nā waiwai waena: inā hiki i ka ʻili waena ke hōʻike i nā hōʻailona ultrasonic, mālama ia i ka pololei paʻa (pololei maʻamau a hiki i ka ± 0.25% FS) me ka linearity maikaʻi loa a me ka hana hou ʻana o ka ʻikepili kiʻekiʻe.

4. Ke akamai kiʻekiʻe a me nā kumukūʻai mālama haʻahaʻa

Hoʻohui nui ʻia nā mika pae ultrasonic o kēia wā me nā microprocessors, i lako me nā hana e like me ka uku mahana aunoa, ka ʻike ʻana i nā hōʻailona leo akamai a me ka ʻike ponoʻī ʻana i ka hewa. Hiki i kēia mau hana ke hoʻopau koke i nā hōʻailona hoʻopilikia a hōʻemi i nā hewa ana. Pono ka mālama ʻana i kēlā me kēia lā i ka hoʻomaʻemaʻe manawa o ka ʻili probe, me ka ʻole o ka calibration pinepine a i ʻole ka hoʻololi ʻana i nā ʻāpana ʻē aʻe. ʻOi aku ka haʻahaʻa o ke kumukūʻai hana a me ka mālama ʻana ma mua o nā mika pae ʻano pili (e laʻa, ʻano lana a me ke ʻano kaomi ʻokoʻa).

5. Hoʻohālikelike maikaʻi a me ka hoʻohui ʻōnaehana maʻalahi

Kākoʻo ia i nā hoʻopuka hōʻailona maʻamau he nui e like me 4-20mA a me RS485 (Modbus protocol), hiki ke hoʻopili pololei ʻia i nā ʻōnaehana kaohi e like me PLC, DCS a me nā kamepiula ʻoihana. Hiki i kēia ke nānā mamao, ka hoʻopaʻa ʻikepili a me ka kaohi aunoa, e hoʻokō ana i nā pono hoʻonui kikohoʻe o ka Industrial Internet of Things (IIoT).
