Nekuvandudzwa kwenguva, maindasitiri akadai sevatsvanyiriri vesainzi, Hvac, macomputer, makamuri emakomputa, erospace, uye magetsi anowedzera kuti awane kushandiswa kwehumiditySensors. Iko kudiwa kwechigadzirwa mhando kuri kukwira uye kukwirira, uye kutonga kwezvakatipoteredzatembirichauye humidity, pamwe nekuongorora uye kuongororwa kwezvinhu zvinyoro-nyoro zvezvishandiso zveindasitiri, zvose zvakajairikatechnicalzvinodiwa. Humidity sensors uye yekunyorova kuyerwa maindasitiri akabuda mu1990s. Mashandisiro Aungaita Kuti Akanyorova Sensors zvinobudirira uye Maitiro Ekutongakuitaof humidity sensors inoramba iri nzvimbo yakaoma yehunyanzvi hwehunyanzvi hwemushandisi wepakati.
Heano mamwe mareferensi kwauri pane masarudzo yekusarudza humidity sensors:
Kuiswa uye hunhu hweanonyadzisa sensors: kunyaradza sensors kwakakamurwa kuita kuramba-rudzi uyecapacitance-Type, uye fomu yekutanga yechigadzirwa ndeyekukanda zvinhu zvekunzwa pane substrate kuti aumbe mresing membrane. MushuremvuraVapori mumhepo inodhindwa pane yekunzwa pane zvekunzwa, kusavimbika uye dielelectric inogara ichichinja chinhu chakakosha, nokudaro ichigadzira chinhu chinonaka-chinomarara.
Kunyatsogadzikana uye kwenguva refu-kugadzikana kweiyo: Iyo yekunyatsoita yeanonyorova sensors inofanira kusvika ± 2% kusvika ± 5% rh. Zvakaoma kuzadzisa iyi nhanho, uye kazhinji, kudhira kuri mukati me ± 2%. Kunyangwe kumusoro.
TembirichaCOEFORIENT YEMUKADZISISA Sensors: Kuwedzera pakuve nehanya nekunyaradza kwezvakatipoteredza, vanyaradzo sensors zvakare vanonzwisa tsitsi zvakanyanya nekushisa tembiricha. Iyo tembiricha inoenderana inowanzoitika mukati me0.2 kusvika 0.8% RH / ℃, uye vamwe vanogona kusiyana zvichienderana nekunyorova kwehama. Iyo Linear tembiricha yekushomeka kweiyo sensity sensors zvakananga zvinokanganisa mhedzisiro, uye isiri-mutsara tembiricha inowanzotadza kuwana mhinduro dzakanaka.CheteNemahara tembiricha turnature yekutsvagisa mari yekubhadhara inogona kuitika. Iyo yekushandisa tembiricha yemhando yakawanda yekunyorova sensors yakaoma kupfuura 40 ℃.
Simbakugovera sensors sensors: zvizhinji zvinyoro-nyoro-zvinyoro-nyoro zvigadzirwa zvakadai sesimbi oxide ceramics, polymers, uye lithium chlorides shanduko kana kutadza kana uchishandisa dcvoltage. Naizvozvo, idzi dzinorema sensors dzinofanirwa kuve dzakapihwa ne accsimba.
Kuchinjana: Parizvino, pane dambudziko rakakosha nekuchinja kwekunyanyisa sensors. Sensors of the modewu imwe chete haigone kupindamo, iyo inokanganisa zvakanyanya kushandiswa uye inowedzera matambudziko ekugadzirisa uye kutumwa. Vamwe vagadziri vakaita nharo dzakasiyana siyana mune izvi uye vakawana mibairo yakanaka.
Humidity calibration: calibration yeushity yakaomesesa kupfuura kuumbwa kwekushisa tembiricha. Standard Thermometers inowanzo shandiswa kudziya kwekushisa, asi kune humidity calibration, yakazara sal sal solution nzira dzinowanzo shandiswa, uye tembiricha inofanirwa kuyerwa.
Nzira dzinoverengeka dzekutanga kutonga kuita kwekunyanyisa sensors: Mukushaikwa kwekunetseka kwekunyanyisa sensors, dzimwe nzira dziri nyore uye dzakareruka dzinogona kushandiswa kutonga mashandiro ezvinonhuwira.
Conction gadziriro: Tenga zvinopfuura zviviri zvinonyadzisa sensors yemhando imwechete uye mugadziri. Zvakanyanya, zviri nani. Vaise pamwe chete uye enzanisa izvo zvinobuda zvinobuda. Pasi pemamiriro ezvinhu akagadzikana, tarisa kuenderana kwebvunzo. Kuwedzera kuongororwa kunogona kuitwa nekurekodha pamisangano mukati memaawa makumi maviri nemana, uye nekucherekedza mukushomeka kwakasiyana-siyana, zvakazara
Humidity kunzwa nekuputika nemuromo kana kushandisa dzimwe nzira dzekunyengedza: Cherekedza pfungwa dzayo, kubereka, kunyorova kwekuita uye kusagadziriswa kwechigadzirwa uye huwandu hwakanyanya hwechigadzirwa.
Kuedza mumabhokisi akavhurika uye akafashika: Enzanisa uye kuyedza kana ivo vachisarirana, uye vanoona iyo inokonzeresa.
Kuedza kumusoro uye kwakaderera tembiricha (zvinoenderana nemabhuku ebhuku racho): Bvunzo
Kuita kwechigadzirwa chakazopera kunoenderana nenzira dzakakwana uye dzakakodzera dzekuchenesa dzeMhando Yekuongorora Dhipatimendi. The thekugezeraSalum Solution inoshandiswa kune calibration, kana chigadzirwa chinogona kufananidzwa uye kuedzwa. Kureba-nguva yekusagadzikana panguva yekushandiswa kwenguva refu kwechigadzirwa zvakare inodiwa kuti inyanye kusanzwisisika kutonga kunaka kweiyo humidity sensity sensor.
Kuongororwa kwezvigadzirwa zvakati sensor pamusika: Mazhinji epamba uye ekunze humidity sensor zvigadzirwa zvakabuda pamusika, necapacance-mhando nyoro-sensitivezvinhu zvinowanzoitika. Mhando dzekusvinira zvinhu zvinonyanya kusanganisira polymers, lithiumchloride, uye simbi nzombe.
Zvakanakira zveCapacance-mhando zvinyoro-nyoro-zvinonyanyisa zvinhu zvakakurumidza kupindura kumhanya, saizi diki, uye mutsika wakanaka. Ivo vane kutsiga. Zvimwe zvigadzirwa zvekunze zvinewo zvakakwirira-tembiricha inoshanda. Nekudaro, zvigadzirwa zvepamusoro-zvekuita zverudzi urwu zvinonyanya kubva kune dzimwe nyika uye zvakadhura. Zvimwe zvigadzirwa zvakaderera-zvakadhura pamusika zvinowanzotadza kusangana nezvirevo zviri pamusoro apa, nerombo rutsinye, kusawirirana, uye kubereka. Iko kusiyanisa mune yakadzika uye yepamusoro humidity matsvina (pazasi 30% rh uye pamusoro 80% rh) yakakosha. Zvimwe zvigadzirwa zvinoshandisa imwe-chip maikorofoni yekubhadharwa uye kururamisa, iyo inoderedza chokwadi uye inosvitsa zvikanganiso zvekutsauka kukuru uye mutsara murombo. Pasinei nekukwira kana kuderera-kupedzisa capacitance-mhando zvinyoro-nyoro-zvinonyatsoita zvinhu, kugadzikana kwenguva refu hakuna kunaka. Mushure mekushandisa kwenguva refu, Drift inowanzo kuve yakanyanya, uye kusiana mumanyoro-nyorokugonaMaitiro ari paPF Level. A 1% RH Shanduko isingasviki 0.5 PF, uye kufambisa kwehuwandu hwekugona kunowanzo kukonzera zvikanganiso zvemakumi e rh%. Mazhinji aungza-mhando zvinyoro-nyoro-zvinyoro-zvinhu zvisina basa hazviite kushanda pakubata pamusoro pegumi 40 ℃, uye kazhinji vanokundikana kana kukuvara.
Zvinhu zvekuvaraidza zvinyoro-nyoro-zvinyoro-nyoro zvine zvimwe zvikanganiso maererano nezvokupokana kwekumanikidza. Vanowanzoda huwandu hwakanyanya hwekuchena munharaunda. Zvimwe zvigadzirwa zvakare zvinowanzo kutadza sekutadza kwechiedza uye kutadza static. Metal oxide exide kunyorodza sensors ane zvimwe zvakangoita seyakanaka okusimudzira sensors, asi guruva poresi rinogona kukonzera kukonzeresa kukundikana. Kazhinji, nzira yekusaisa yekubvisa guruva inoshandiswa, asi mhedzisiro haina kunaka, uye haigone kushandiswa munzvimbo dzinopisa uye dzinoputika uye dzinoputika. Alumina Sensing Zvigadzirwa hazvigone kukunda kushaya simba kwe "kuchembera kwechisikirwo" chechimiro chechiso, uye kusavimbika hakusi kugadzikana. Metal oxide ceramic humidity sensors ane iyo kusagadzikana kwekugadzikana kwemberi-refu.
Lithium chloride akanyorova sensors ane mukana wakakurumbira wekutonga kwakanaka kwazvo kwenguva refu. Kuburikidza nekugadzirwa kwakasimba, zviridzwa zvakagadzirwa uye sensors zvinogona kuzadzisa zvakanyanyisa kurongeka, kugadzikana kwakanaka, uye mutsara, kuona hupenyu hwakatendeka hwebasa. Lithium chloride honylity sensors haigone kutsiviwa nezvimwe zvinhu zvekunzwa maererano nekugadzikana kwenguva refu.
