He aha ke ʻano o ke kiʻekiʻe wela a me ka haʻahaʻa haʻahaʻa?

Nā ʻike wela kiʻekiʻe a me ka haʻahaʻahoʻohana pinepine ʻia i ka mālama wai. ʻO ka mea kānana Resin kahi ʻano mea wai maʻemaʻe i hana ʻia e ka hana hana. Hoʻohana pinepine ʻia i ka wai inu a me ka kānana wai maʻemaʻe. Ma keʻano he huahana kānana, hoʻohana nuiʻia ka mea kānana i nā wahiʻoihana likeʻole. Ua maʻa nā mea kānana o nā mea like ʻole i nā pono ʻoihana like ʻole, a ʻo ke kūʻai ʻana a me ka hoʻohana ʻana i nā mea kānana e koho mau i nā huahana kūpono e pili ana i kā lākou pono ponoʻī.

I. Hoolauna

ʻO ka mahana a me ka haʻahaʻa ʻelua o nā kumu kaiapuni koʻikoʻi e pono e nānā i nā ʻoihana like ʻole a me nā noi. Hoʻohana ʻia nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa e ana i kēia mau ʻāpana e hōʻoia i ka palekana, hoʻomaikaʻi i ka pono, a me nā kaʻina hana. E kūkākūkā kēia pou blog i ke ʻano o nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa, me nā ʻano like ʻole a me nā ʻāpana a me ke ʻano o ka hana.

II. Nā ʻano o nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa

Loaʻa kekahi mau ʻano o ka wela kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, kēlā me kēia me nā hiʻohiʻona kūʻokoʻa a me nā pono. ʻO nā ʻano i hoʻohana pinepine ʻia:

1.Nā mea ʻike maka wela (RTD):

Hoʻohana kēia mau mea ʻike i ka hoʻololi ʻana i ke kūʻē o kahi mea e ana i ka mahana. Ua pololei loa lākou a loaʻa ka laulā wela ākea, akā ʻoi aku ka pipiʻi a me ka palupalu.

2.Thermocouple:

Hoʻohana kēia mau mea ʻike i ka ʻokoʻa ʻokoʻa uila ma waena o ʻelua metala like ʻole e ana i ka mahana. ʻAʻole kūʻai nui lākou a paʻakikī akā ʻoi aku ka pololei ma mua o nā RTD a loaʻa ka palena wela.

3. Nā mea wela:

Hoʻohana kēia mau mea ʻike i ka hoʻololi ʻana i ke kūʻē o nā mea semiconductor e ana i ka mahana. He liʻiliʻi lākou a he mea kūʻai ʻole akā ʻaʻole pololei ma mua o nā RTD a loaʻa ka palena wela.

E pili ana i ka haʻahaʻa, aia kekahi mau mea ʻike, e like me ka capacitive, resistive, a me ka optical. Loaʻa i kēlā me kēia o lākou kona mau pono a me nā hemahema.

III. ʻO nā ʻāpana o kahi kiʻekiʻe wela a me ka haʻahaʻa haʻahaʻa

ʻO ke ʻano o kahi mea ʻike wela kiʻekiʻe a me ka haʻahaʻa haʻahaʻa e komo pū kekahi mau mea nui:

• ʻO ka mea ʻike: ʻO kēia ka ʻāpana o ka sensor e ana i ka mahana a me ka haʻahaʻa. Hiki ke hana ʻia i nā mea like ʻole, ma muli o ke ʻano o ka sensor.
• ʻO ka mea hōʻailona hōʻailona: Hoʻololi kēia mea i ka hōʻailona uila mai ka mea ʻike i kahi ʻano hiki ke hoʻouna ʻia a heluhelu ʻia e nā mea hana ʻē aʻe.
• Ka transmitter: Hoʻouna kēia ʻāpana i ka hōʻailona mai ka sensor i kahi ʻōnaehana mamao a i ʻole ka mana.
• ʻO ka mea hōʻike a i ʻole mea hoʻopuka: Hōʻike kēia ʻāpana i ka heluhelu ʻana i ka mahana a me ka haʻahaʻa, maʻamau ka heluhelu analog a i ʻole ka helu helu kikohoʻe.

IV. Pehea e hana ai nā mea ʻike wela a me ka haʻahaʻa

ʻO ka hana o kahi mea ʻike wela kiʻekiʻe a me ka haʻahaʻa e pili ana i ke ʻano o ka ʻike i hoʻohana ʻia. Ma keʻano laulā, e pane ka mea ʻike o ka mea ʻike i nā loli o ka mahana a me ka haʻahaʻa ma o ka hoʻololi ʻana i kāna mau waiwai uila. A laila hoʻololi ka mea hōʻailona hōʻailona i kēia hoʻololi i nā waiwai uila i hōʻailona hiki ke heluhelu ʻia. Hoʻouna ka transmitter i kēia hōʻailona i kahi mākaʻikaʻi mamao a i ʻole ʻōnaehana hoʻomalu, kahi e hōʻike ʻia ai ka heluhelu ʻana o ka mahana a me ka haʻahaʻa a hoʻohana ʻia e kāohi i nā mea ʻē aʻe.

He hana koʻikoʻi ka calibration i ke kaʻina hana, a ʻo ia ka mea e hōʻoia i ke ana pono ʻana o ka sensor i ka mahana a i ʻole ka haʻahaʻa. Hiki iā ia ke hana ma ka hoʻohālikelike ʻana i nā heluhelu a ka sensor i kahi maʻamau i ʻike ʻia a i ʻole ka hoʻohana ʻana i kahi hāmeʻa calibration.

V. Nā noi o nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa

Loaʻa nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa i nā noi like ʻole ma waena o nā ʻoihana like ʻole a me nā kaiapuni. Aia kekahi mau laʻana:

• Nā hoʻonohonoho ʻenehana: Hoʻohana ʻia nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa, e like me ka nānā ʻana i ka umu ahi, i nā kaʻina hana e hōʻoia i ka pae o ka mahana a me ka haʻahaʻa i loko o nā palena palekana.
• Pūnaehana HVAC: Hoʻohana ʻia kēia mau mea ʻike i ka hoʻomehana ʻana, ka ea, a me nā ʻōnaehana ea e nānā a mālama i nā pae wela a me ka haʻahaʻa o nā hale a me nā hale ʻē aʻe.
• Ka nānā ʻana i ka lewa: Hoʻohana ʻia nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa i nā kikowaena meteorological e ana i ka mahana a me ka haʻahaʻa o ka ea.
• Mahiai:Hoʻohana ʻia kēia mau mea ʻike i loko o nā hale ʻōmaʻomaʻo a me nā hoʻonohonoho mahiʻai ʻē aʻe e nānā a mālama i ka pae wela a me ka haʻahaʻa e hoʻomaikaʻi i ka ulu ʻana o ka mea kanu a hōʻemi i ka nalowale o nā mea kanu.

VI. Ka hopena

He mea nui nā mea ʻike wela a me ka haʻahaʻa no ka nānā ʻana a me ka mālama ʻana i ka mahana a me ka haʻahaʻa ma nā ʻoihana like ʻole a me nā noi.

Loaʻa nā ʻano sensor, kēlā me kēia me nā hiʻohiʻona kūʻokoʻa a me nā pono. Hoʻokomo pinepine ʻia kahi ʻōnaehana ʻike wela a me ka haʻahaʻa haʻahaʻa i kahi mea ʻike, kahi mea hoʻomaʻamaʻa hōʻailona, ​​​​mea hoʻouna, a me kahi mea hōʻike a i ʻole mea hoʻopuka.

ʻO ka hana o kēia mau mea ʻike e pili ana i ke ʻano o ka sensor i hoʻohana ʻia a calibrated e hōʻoia i ka pololei. Loaʻa i nā mea ʻike wela kiʻekiʻe a me ka haʻahaʻa haʻahaʻa nā noi, mai nā ʻoihana ʻoihana a i ka nānā ʻana i ka wā a me ka mahiʻai. Ke holomua nei ka ʻenehana, e hoʻomaikaʻi mau ana ka pololei a me ka hiki o kēia mau mea ʻike, e hana ana iā lākou i mea hana pono no ka hōʻoia ʻana i ka palekana, hoʻomaikaʻi i ka pono, a me nā kaʻina hana.

He mea nui loa ke koho ʻana i ka hoʻonohonoho pono ʻana o ka mīkini e hōʻoia i ka pololei a me ka wikiwiki o ka pane ʻana a pale i ka sensor mai ka pōʻino. E like me kāu mau koi ʻāpana ana, e ana i ka mea ʻike maka kehau ma kahi hoʻonohonoho paʻa, e like me ka wā o ka mīkini is ma ka puka o ke keena keena, e ana ka dew point sensor ʻO ia ka hau o ke kinoea ke komo i loko o ka pahu, ʻaʻole e ʻike ʻia ke kinoea i loko o ka pahu ponoʻī a i ʻole kekahi mau wai i ka wā hana.

Kemea hoʻolele dew pointAia ka mea ma ka puka makani, e ana ka mea ʻike i ka wai e komo ana i loko o ka ʻōnaehana ma o ka inlet a i ʻole leakage a me ka wai i hoʻokuʻu ʻia i ka wā hana. HENGKOHT608 moʻo dew point sensor/transmitterloaʻa ka pono o ka precision kiʻekiʻe, ka hoʻohana haʻahaʻa haʻahaʻa a me ka kūlike maikaʻi.
