Momwe Humidity Sensor Imagwirira Ntchito Zonse Zomwe Muyenera Kudziwa

Momwe Sensor Humidity Imagwirira Ntchito

* Kodi sensa ya chinyezi ndi chiyani, ndipo chifukwa chiyani ili yofunika pa moyo ndi kupanga. ?

Chinyezi ndizofunikira kwambiri zachilengedwe zomwe zingakhudze mbali zambiri za moyo wathu, kuchokera ku thanzi lathu ndi chitonthozo kupita ku machitidwe a mafakitale ndi zipangizo zamagetsi. Sensa ya chinyezi ndi zida zomwe zimayesa kuchuluka kwa nthunzi mumlengalenga, ndipo zimagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo kuyang'anira nyengo, machitidwe a HVAC, kusunga chakudya, ndi zipangizo zamankhwala, komanso kwa ogula, mafakitale, biomedical, ndi chilengedwe. , etc. ntchito zoyezera ndi kuyang'anira Chinyezi.

* Kodi sensa ya chinyezi imagwira ntchito bwanji?

Mwachidule, ma probes a Humidity Sensor amazindikira kusintha komwe kumasintha kutentha kapena magetsi mumlengalenga. Ma probe ambiri a chinyezi amadalira ma conductor awiri amagetsi (electrodes) okhala ndi filimu yosakhala ya conductive polima pakati pa maelekitirodi kuti apange gawo lamagetsi. Chinyezi chochokera kumlengalenga wozungulira chimasonkhanitsidwa pafilimuyo, yomwe imayambitsa kusintha kwa magetsi pakati pa ma electrode awiri. Kusintha kumeneku kumasinthidwa kukhala muyeso wa digito kuti muwerenge Chinyezi chachibale, potengera kutentha kwa mpweya.

The humidity sensor probe ndiyofunikira kwambiri pa sensor yonse. HENGKO ndi katswiri wopanga mitundu ya sintered metal humidity sensor probes. Ntchito yayikulu yowunikira zovuta zina. chifukwa cha kulimba kwawo komanso kukana dzimbiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo ovuta.

Chifukwa chake tilankhule nafe kuti mumve zambiri za ma probes a chinyezi kapena OEM kuti mupange ma sensor apadera a chinyezi pazida zanu ndi polojekiti. Pansipa pali ma probe odziwika a chinyezi cha sensa ya chinyezi chamakampani. Chonde yang'anani.

* Ma sensor a Chinyezi - Gulu ndi Mfundo Zogwirira Ntchito

Mitundu ya Sensor Humidity

Mitundu ingapo ya masensa a chinyezi imapezeka pamsika, iliyonse ili ndi zabwino ndi zovuta zake. Pali mitundu inayi ya masensa a chinyezi kutengera mfundo zogwirira ntchito ndi zida za sensa: capacitive, resistive, thermal conductivity, ndi psychrometric.

1) Capacitive Humidity Sensors

Capacitive humidity sensors ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri. Amagwira ntchito poyesa kusintha kwa dielectric constant wa zinthu poyankha kusintha kwa Chinyezi. Dongosolo la dielectric limayesa kuthekera kwazinthu kusunga mphamvu zamagetsi pagawo lamagetsi.

Ma capacitive humidity sensors nthawi zambiri amakhala ndi maelekitirodi awiri, imodzi yokhala ndi hygroscopic material yomwe imatenga mpweya wamadzi kuchokera mumlengalenga. Pamene zinthu za hygroscopic zimatenga mpweya wa madzi, zimayambitsa kusintha kwa dielectric nthawi zonse pakati pa ma electrode awiri, omwe amayesedwa ndi sensa.

        1. Ubwino wa Capacitive Humidity Sensors

1.1 Mphamvu yotulutsa ili pafupi ndi mzere.

Ma sensor a resistive humidity, omwe amadziwikanso kuti ma hygrometers, amagwira ntchito poyesa kusintha kwa mphamvu yamagetsi ya chinthu poyankha kusintha kwa Chinyezi. Mtundu wodziwika kwambiri wa sensor yamadzi yopingasa ndi sensor yochokera ku polima, yomwe imakhala ndi filimu ya polima yomwe imasintha kukana kwake ikakumana ndi nthunzi wamadzi.

Pamene filimu ya polima imatenga mpweya wa madzi kuchokera mumlengalenga, imatupa ndikukhala bwino kwambiri, zomwe zimawonjezera mphamvu zamagetsi zomwe zimadutsa mu sensa. Kusintha kwa kukana kumeneku kumayenderana ndi kuchuluka kwa nthunzi yamadzi mumpweya ndipo kungayesedwe kuti mudziwe kuchuluka kwa chinyezi.

Ubwino wa Resistive Humidity Sensors

1. Mtengo wotsika
2. Kukula Kwakung'ono
3. Mtunda pakati pa sensa ndi chigawo cha chizindikiro ukhoza kukhala waukulu (woyenera ntchito zakutali).
4. Zosinthana kwambiri popeza palibe miyezo yosinthira.

Kuipa kwa Resistive Humidity Sensors

Resistive Humidity Sensor imakhudzidwa ndi nthunzi wamankhwala ndi zowononga zina.

Zowerengera zimatha kusintha ngati zigwiritsidwa ntchito ndi zinthu zosungunuka m'madzi.

Kugwiritsa Ntchito Resistive Humidity Sensors:

Resistive kapena Electrical Conductive Humidity sensors ndi masensa otsika mtengo okhala ndi kukula kochepa. Nthawi zambiri amagwiritsidwa ntchito m'mafakitale, nyumba, nyumba, komanso malonda.

3) Thermal Conductivity Humidity Sensors

Thermal conductivity humidity sensors amagwira ntchito poyesa kutenthetsa kwamafuta osakanikirana ndi gasi poyankha kusintha kwa Chinyezi. Amakhala ndi chinthu chomva kutentha komanso chojambulira kutentha chomwe chimayesa kusiyana kwa kutentha pakati pawo.

Pamene chinthu chomva chimatenga mpweya wa madzi, chimachepetsa kutentha kwake, zomwe zimapangitsa kusintha kwa kutentha komwe sensor ya kutentha imatha kuyeza. Kusintha kwa kutentha kumeneku kumayenderana ndi kuchuluka kwa nthunzi yamadzi mumpweya ndipo kungagwiritsidwe ntchito kudziwa mlingo wa chinyezi.

Ubwino wa Thermal Conductivity Humidity Sensors

1. Yoyenera kumadera otentha kwambiri komanso malo owononga kwambiri.

2. Cholimba kwambiri

3. Kusamvana kwakukulu poyerekeza ndi mitundu ina

Kuipa kwa Thermal Conductivity Humidity Sensors

Kukumana ndi mpweya uliwonse wokhala ndi kutentha kosiyana ndi nayitrojeni kumatha kukhudza muyeso wowerengera.

Kugwiritsa Ntchito Ma Thermal Conductivity Humidity Sensors

Zina mwazomwe zimagwiritsidwa ntchito pa Thermal Conductivity Humidity Sensors ndi:

Kuyanika ng'anjo

Zomera zamankhwala
