Kuzindikira chinyezi ndi kutentha ndikofunikira, makamaka m'nyengo yozizira yomwe ambirife tikukumana nayo pano. Ndizofunikira osati m'moyo watsiku ndi tsiku, komanso m'makampani opanga zinthu. Mwachitsanzo, makina otumizira chinyezi akaikidwa bwino ndi kugwiritsidwa ntchito, makina opangira makina amatha kudziwa ngati mpweya umakhala wouma kwambiri kapena wonyowa kwambiri kuti usatonthozedwe.
Ndiye kodi sensor ya kutentha ndi chinyezi imagwira ntchito bwanji?
Choyamba, Sensor ya Kutentha
Masensa a kutentha amagwiritsidwa ntchito kudziwa kuchuluka kwa kutentha kapena kuzizira kopangidwa ndi chinthu kapena dongosolo. Imatha kuzindikira / kuzindikira kusintha kulikonse kwa kutentha ndi kutulutsa kwa analogi kapena ma siginecha a digito. Masensa a kutentha amagwera m'magulu awiri: Zowunikira kutentha kwa kukhudzana ziyenera kukhudzana ndi chinthu chomwe chiyenera kumveka ndikuwunika kusintha kwa kutentha kupyolera mu conduction. Zoyezera kutentha zimawunika kusintha kwa kutentha ndi convection ndi radiation.
Chachiwiri,Sensor ya Humidity
Chinyezi ndi kuchuluka kwa nthunzi wamadzi mumpweya. Kuchuluka kwa nthunzi yamadzi mumlengalenga kumakhudza chitonthozo cha anthu ndi njira zosiyanasiyana zamakampani. Nthunzi wamadzi umakhudzanso njira zosiyanasiyana zakuthupi, zamankhwala komanso zachilengedwe. Masensa a chinyezi amagwira ntchito pozindikira kusintha kwa magetsi kapena kutentha kwa mpweya. Pali mitundu itatu yofunikira ya masensa a chinyezi: capacitive, resistive and thermal. Iliyonse mwa mitundu itatuyi imayang'anira mosalekeza kusintha kwakung'ono mumlengalenga kuwerengera chinyezi cha mpweya.
A capacitive humidity sensorzimatsimikizira chinyezi chambiri poyika kachingwe kakang'ono kachitsulo okusayidi pakati pa maelekitirodi awiri. Mphamvu yamagetsi ya ma oxides achitsulo imasiyanasiyana ndi chinyezi chapafupi ndi mlengalenga. Ntchito zazikuluzikulu ndi nyengo, malonda ndi mafakitale. Ma sensor a resistive humidity amagwiritsa ntchito ayoni mumchere kuti ayeze kutsekeka kwa magetsi kwa ma atomu. The elekitirodi kukana mbali zonse za mchere sing'anga kusintha ndi chinyezi. Masensa awiri otentha amayendetsa magetsi potengera chinyezi cha mpweya wozungulira. Sensa imodzi imasindikizidwa mu nayitrogeni wowuma, pomwe ina imawululidwa ndi mpweya wozungulira. Kusiyana pakati pa mfundo ziwirizi kumasonyeza chinyezi chapafupi.
Sensa ya chinyezindi chipangizo chamagetsi chomwe chimazindikira chinyezi m'malo ndikuchisintha kukhala chizindikiro chamagetsi. Masensa a chinyezi amabwera mumitundu yosiyanasiyana komanso masinthidwe; Zina zimaphatikizidwa muzipangizo zam'manja, monga mafoni a m'manja, pamene zina zimaphatikizidwa ndi machitidwe akuluakulu ophatikizidwa, monga machitidwe owunikira khalidwe la mpweya. Mwachitsanzo, Hengko kutentha ndi chinyezi transmitters amagwiritsidwa ntchito kwambiri mundizanyengo, zamankhwala, zamagalimoto ndi za HVAC ndi mafakitale opanga. Industrial grade high precision humidity sensor imatha kutsimikizira kuyeza kolondola mumitundu yonse yazovuta.
Chachitatu, Njira Yowerengera
Masensa a chinyezi amagawidwa m'magulu amtundu wa chinyezi (RH) ndi masensa absolute humidity (AH) malinga ndi njira yomwe imagwiritsidwa ntchito powerengera chinyezi. Chinyezi chofananira chimatsimikiziridwa poyerekezera kuwerengera kwa chinyezi chenicheni pa kutentha komwe kumaperekedwa ndi chinyezi chambiri mumlengalenga pa kutenthako. Chifukwa chake, kachipangizo kakang'ono ka chinyezi kamayenera kuyeza kutentha kuti awerengere kuchuluka kwa chinyezi. Mtheradi chinyezi, mosiyana, anatsimikiza popanda kutentha.
Choyamba, kugwiritsa ntchito Sensors
Zowunikira kutentha zimakhala ndi ntchito zopanda malire, chifukwa zimagwiritsidwanso ntchito pazinthu zosiyanasiyana zamankhwala, kuphatikizapo zida za magnetic resonance imaging (MRI) ndi ma ultrasound scanner. Masensa a kutentha amagwiritsidwa ntchito pazida zosiyanasiyana m'nyumba mwathu, kuchokera m'mafiriji ndi mafiriji kupita ku masitovu ndi mavuni kuti atsimikizire kuti akutenthedwa ndi kutentha koyenera kuphika, maswiti / ma heaters. Ngakhale ma charger wamba amawagwiritsa ntchito kuti apewe kuchulukitsitsa kapena kutsitsa batire potengera kutentha kwake.
Ngakhale zingawoneke kuti sizingatheke kuti kuchotsa mafuta kudzagwiritsidwa ntchito pazidziwitso za kutentha, ndizofunikira kuti zitsimikizidwe kuti ndizotetezeka komanso zogwira mtima zochotsa mafuta. Mafuta amafuta amakhala ndi sensa ya kutentha kumapeto kwake yomwe imachenjeza ogwira ntchito pamene ikufunika kusiya kubowola, chifukwa ikatentha kwambiri (chifukwa imapitirizabe kukumba pansi), imatha kutentha kwambiri ndikusweka.
Sensa ya kutentha imapangidwira mu radiator ya galimoto. Izi ndizofunikira, chifukwa madzi ozungulira mu injini yagalimoto akafika kutentha kosatetezeka, amakuchenjezani kuti, ngati apitilira, angayambitse kulephera kwa injini, komanso kuwongolera kwanyengo yagalimoto /. Mwa kusintha magawo malinga ndi kutentha, izi zimapewedwa bwino popanda kuyika dalaivala pachiwopsezo.
Machitidwe a HVACzimafunika kuyeza kutentha kuti zithandize kusunga kutentha kwabwino m'chipinda kapena nyumba. Masensa a kutentha amafunikira pafupifupi pafupifupi ma air-conditioner ndi makina onse m'nyumba ndi maofesi. Angagwiritsidwenso ntchito kuzindikira kutayikira pozindikira kusayembekezeka kwa kutentha.
Mphamvu zongowonjezedwanso zimadalira zowunikira kutentha kuti ziziyenda bwino. Mapampu otentha adzuwa, makina opangira mphepo, kugwiritsa ntchito kuyatsa kwa biomass ndi magwero a kutentha kwapansi zonse zimadalira kuwongolera kutentha ndi kuyeza.
Chachisanu, Precision Calibration
Kuti mudziwe kulondola kwa sensa, zomwe mwapeza zimafaniziridwa ndi zomwe zimatchulidwa. Kuti tiwonetsetse kulondola kwa masensa a chinyezi, tidapanga miyezo pogwiritsa ntchito njira ya "saturated salt". Mwachidule, pamene mchere wina (mankhwala a ionic monga mchere wa tebulo kapena potaziyamu chloride) amasungunuka m'madzi, amapanga mpweya wodziwika bwino.
Izimankhwala katunduamagwiritsidwa ntchito kupanga microenvironment yokhala ndi chiwerengero chodziwika bwino cha chinyezi (RH) (muyezo wofotokozera), womwe umawerengedwa ndi sensa. Zowonjezereka, tidzakonzekera yankho mu thanki yosindikizidwa kuti tigwire mlengalenga, ndikuyika sensa yolumikizidwa mu thanki yosindikizidwa. Pambuyo pake, sensor imawerengedwa mobwerezabwereza ndipo zikhalidwe zimalembedwa.
Titha kupanga mbiri ya sensa yoyesedwa pobwereza njirayi ndi mchere wambiri wosiyanasiyana, womwe umatulutsa chinyezi chosiyana. Chifukwa timadziwa chinyezi chachibale cha microenvi iliyonserpang'ono, tingayerekezesensorkuwerenga ndi zikhalidwe zomwe zimadziwika kuti zitsimikizire kulondola kwa sensa.
Ngati kupatukako kuli kwakukulu koma kosatheka, titha kuwongolera kulondola kwa kuyezako pogwiritsa ntchito njira yosinthira masamu mu pulogalamuyo.
