Pehea e hana ai ka Humidity Sensor i nā mea a pau āu e ʻike ai

Pehea ka hana ʻana o ka haʻahaʻa haʻahaʻa

* He aha ka mea ʻike haʻahaʻa, a no ke aha he mea nui ia no ke ola a me ka hana. ?

He mea koʻikoʻi ka haʻahaʻa kaiapuni e hiki ke hoʻopilikia i nā ʻano he nui o ko mākou ola, mai ko mākou olakino a hōʻoluʻolu a hiki i ka hana ʻana i nā kaʻina hana ʻenehana a me nā mea uila. ʻO nā mea ʻike haʻahaʻa haʻahaʻa nā mea e ana i ka nui o ka mahu wai i ka lewa, a hoʻohana ʻia lākou i kahi ākea o nā noi, me ka nānā ʻana i ka wā, nā ʻōnaehana HVAC, mālama meaʻai, a me nā mea lapaʻau, no ka mea kūʻai aku, ʻoihana, biomedical, a me ke kaiapuni. , etc. nā noi no ke ana ʻana a me ka nānā ʻana i ka Humidity.

* Pehea ka hana ʻana o ka mea ʻike haʻahaʻa?

I ka pōkole, ʻike nā probes o ka Humidity Sensor i nā loli e hoʻololi i ka mahana a i ʻole ka uila uila i ka lewa. Ke hilinaʻi nei ka hapa nui o nā mea hoʻoheheʻe haʻahaʻa ma luna o ʻelua mea hoʻokele uila (electrodes) me kahi kiʻiʻoniʻoni polymer non-conductive ma waena o nā electrodes e hana i kahi kahua uila. ʻO ka makū mai ka ea a puni e hōʻiliʻili ʻia ma ke kiʻiʻoniʻoni, kahi e hoʻololi ai i ka pae uila ma waena o nā electrodes ʻelua. Hoʻololi ʻia kēia hoʻololi i ana kikohoʻe no ʻoe e heluhelu ai i ka Humidity pili, e noʻonoʻo ana i ka mahana o ka ea.

He mea koʻikoʻi ka ʻimi ʻana i ka haʻahaʻa haʻahaʻa no ka ʻike holoʻokoʻa. He mea hana ʻoihana ʻo HENGKO i nā ʻano ʻano ʻano mea ʻike maka haʻahaʻa metala. ʻO ka noi nui no ka nānā ʻana i ke kūlana paʻakikī. ma muli o ko lākou kūpaʻa maikaʻi loa a me ke kūpaʻa ʻana i ka corrosion, kūpono ia no ka hoʻohana ʻana i nā wahi paʻakikī.

No laila, e kelepona mai iā mākou no nā kikoʻī o nā mea hoʻomaʻamaʻa haʻahaʻa a i ʻole OEM i nā ʻōkuhi sensor haʻahaʻa kūikawā kūikawā no kāu mau mea nānā a me kāu papahana. Ma lalo iho nei kekahi mau ʻimi hoʻonaʻauao kaulana no ka ʻenehana humidity sensor. E ʻoluʻolu e nānā.

* Nā Māmā Haʻahaʻa – Hoʻokaʻawale a me nā Kuʻuna Hana

Nā ʻano o nā mea ʻike haʻahaʻa

Loaʻa nā ʻano mea ʻike haʻahaʻa ma ka mākeke, kēlā me kēia me nā pono a me nā hemahema. Aia he 4 mau ʻano o ka haʻahaʻa haʻahaʻa e pili ana i nā loina hana a me nā mea sensor: capacitive, resistive, thermal conductivity, a me psychrometric.

1) Nā mea hoʻonā haʻahaʻa haʻahaʻa

ʻO nā mea ʻike haʻahaʻa Capacitive kekahi o nā ʻano maʻamau i hoʻohana ʻia. Hana lākou ma ke ana ʻana i nā loli i ka dielectric mau o kahi mea i pane i nā loli i ka Humidity. ʻO ka dielectric mau e ana i ka hiki o kahi mea ke mālama i ka ikehu uila ma ke kahua uila.

ʻElua mau electrodes i uhi ʻia me kahi mea hygroscopic e hoʻopau i ka mahu wai mai ka lewa. Ke komo ka mea hygroscopic i ka mahu wai, hoʻololi ia i ka dielectric mau ma waena o nā electrodes ʻelua, i ana ʻia e ka mea ʻike.

* Kalibration a me ka mālama ʻana

Pono ka calibration i ka hoʻohana ʻana i nā mea ʻike haʻahaʻa e hōʻoia i ka pololei a hilinaʻi. ʻO ka hapa nui o nā mea ʻike haʻahaʻa e koi i ka calibration maʻamau e mālama i ko lākou pololei, a hiki ke hilinaʻi ke alapine o ka calibration i ka noi a me ke ʻano o ka sensor.

Nui nā ʻano hana no ka calibrating humidity sensors me nā mea kuhikuhi me nā pae haʻahaʻa i ʻike ʻia, e like me nā wai paʻakai saturated, a me nā lako calibration kūikawā hiki ke hoʻohua i nā pae haʻahaʻa pololei.

* Nā noi o nā mea ʻike haʻahaʻa

ʻO nā mea ʻike haʻahaʻa he mau mea uila e ana i ka makū a i ʻole ka haʻahaʻa pili i ka lewa. Hoʻohana ʻia lākou i kahi ākea o nā noi, e like me:

1. Pūnaehana HVAC:Hoʻohana ʻia nā mea ʻike haʻahaʻa i nā ʻōnaehana HVAC e kāohi i nā pae haʻahaʻa o loko. Kōkua lākou i ka mālama ʻana i nā pae haʻahaʻa maikaʻi loa, hiki ke hoʻomaikaʻi i ka maikaʻi o ka ea o loko a hoʻemi i ka ulu ʻana o ka maʻi a me ka bacteria.

2. Nā Kūlana Hōkū:Hoʻohana ʻia nā mea ʻike haʻahaʻa i nā keʻena o ka wā e ana i ka haʻahaʻa pili i ka lewa. Hoʻohana ʻia kēia ʻike no ka wānana ʻana i ke ʻano o ke aniau a no ka hāʻawi ʻana i nā wānana ʻano kūpono.

3. Waihona Meaʻai:Hoʻohana ʻia nā mea ʻike haʻahaʻa i nā hale mālama meaʻai e nānā i nā pae haʻahaʻa a pale i ka palaha. Kōkua lākou i ka mālama ʻana i ka ʻoluʻolu o ka wai i nā huahana meaʻai, hiki ke hoʻonui i ko lākou ola.

4. Lapaʻau Lapaʻau:Hoʻohana ʻia nā mea ʻike haʻahaʻa i nā mea lapaʻau e like me nā nebulizers a me nā concentrators oxygen e nānā a mālama i nā pae haʻahaʻa o ka ea e hāʻawi ʻia i nā maʻi.

5. Mahiai:Hoʻohana ʻia nā mea ʻike haʻahaʻa i ka mahiʻai e nānā i ke kiʻekiʻe o ka haʻahaʻa o ka lepo a me ka hoʻomalu ʻana i ka makū o nā hale ʻōmaʻomaʻo. Kōkua lākou i ka hoʻomaikaʻi ʻana i nā hua kanu a hoʻemi i ka hoʻohana ʻana i ka wai.

6. ʻOihana Kaʻa:Hoʻohana ʻia nā mea ʻike haʻahaʻa i ka ʻoihana kaʻa e hoʻomalu i nā pae haʻahaʻa i loko o nā kaʻa. Hiki iā lākou ke pale i ka fogging o nā puka makani, hoʻomaikaʻi i ka maikaʻi o ka ea, a hāʻawi i kahi ʻike hoʻokele ʻoluʻolu.

7. Noi Hana Hana:Hoʻohana ʻia nā sensor humidity i nā noi ʻoihana like ʻole, e like me ka maloʻo, ka uhi ʻana, a me ka paʻi ʻana. Kōkua lākou i ka nānā ʻana a me ka mālama ʻana i nā pae haʻahaʻa i ke kaʻina hana, hiki ke hoʻomaikaʻi i ka maikaʻi o ka huahana hope.

Ma ka holoʻokoʻa, hoʻohana ʻia nā mea ʻike haʻahaʻa i nā noi he nui e nānā a mālama i nā pae haʻahaʻa. Hiki iā lākou ke hoʻomaikaʻi i ka maikaʻi o ka huahana, hoʻemi i ka hoʻohana ʻana i ka ikehu, a hāʻawi i kahi ʻoluʻolu a olakino maikaʻi no nā kānaka a me nā holoholona.

* Pehea e koho ai i kahi noiʻi haʻahaʻa

Eia kekahi mau mea e pono e noʻonoʻo ʻia i ke koho ʻana i kahi Sensor Humidity.

1. pololei:ʻO ka pololei o ka ʻimi haʻahaʻa kahi mea nui e noʻonoʻo ai. E hāʻawi ka ʻimi ʻoi aku ka pololei i nā ana haʻahaʻa pololei. E ʻimi i kahi ʻimi me ka pololei o ka liʻiliʻi o ±2% Relative Humidity (RH).

2. Laulā:E noʻonoʻo i ka laulā o ka Humidity hiki ke ana ʻia ka probe. E koho i kahi ʻimi me kahi laulā e uhi ana i nā pae haʻahaʻa āu e pono ai e ana.
