Kunzwa hunyoro uye tembiricha kwakakosha, kunyanya munguva yechando yakaoma vazhinji vedu tiri kusangana nazvo izvozvi. Izvo zvakakosha kwete chete muhupenyu hwezuva nezuva, asiwo muindasitiri yekugadzira. Semuenzaniso, kana humidity transmitters akaiswa nemazvo uye achishandiswa, kuvaka otomatiki masisitimu anogona kuona kana mhepo yanyanya kuoma kana kunyorova kuti inyaradzwe.
Zvino tembiricha uye humidity sensor inoshanda sei?
Chekutanga, Tembiricha Sensor
Temperature sensors inoshandiswa kuona huwandu hwekupisa kana kutonhora kunogadzirwa nechinhu kana system. Inogona kunzwa / kuona chero shanduko yemuviri mukupisa uye kubuda analog kana masaini edhijitari. Tembiricha sensors inowira mumapoka maviri: Bata tembiricha ma sensors anofanirwa kunge ari mukubata kwenyama nechinhu chinonzwika uye chekutarisa shanduko yekushisa kuburikidza nekuita. Bata tembiricha sensors inotarisisa shanduko yekushisa ne convection uye nemwaranzi.
Chepiri,Humidity Sensor
Humidity huwandu hwemhute yemvura iri mumhepo. Kuwanda kwemhute yemvura mumhepo ine simba pakunyaradza kwevanhu uye maitiro akasiyana-siyana emabhizimisi. Utsi hwemvura hunokanganisawo maitiro akasiyana emuviri, makemikari uye zvipenyu. Humidity sensors inoshanda nekuona shanduko yemagetsi ikozvino kana tembiricha yemhepo. Kune matatu akakosha marudzi ehumidity sensors: capacitive, resistive uye thermal. Imwe neimwe yemhando nhatu icharamba ichitarisa shanduko diki mumhepo kuverenga humidity yemhepo.
A capacitive humidity sensorinosarudza hunyoro hwehukama nekuisa sandwich chidimbu chesimbi okisijeni pakati pema electrode maviri. Simba remagetsi resimbi okisidhi rinosiyana nehunyoro hwemhepo yakapoteredza. Iyo mikuru yekushandisa ndeyemamiriro ekunze, kutengeserana uye maindasitiri. Resistive humidity sensors anoshandisa maion mumunyu kuyera kukanganiswa kwemagetsi kwemaatomu. Iyo electrode resistance kumativi ose emunyu wepakati inoshanduka nehunyoro. Masensa maviri ekupisa anofambisa magetsi zvichienderana nehunyoro hwemhepo yakatenderedza. Imwe sensor inovharirwa mune yakaoma nitrogen, nepo imwe yacho ichiratidzwa kune ambient mhepo. Musiyano uripo pakati pezviviri izvi unoratidza hunyoro hunoenderana.
A humidity sensormudziyo wemagetsi unoona hunyoro munzvimbo uye woushandura kuita chiratidzo chemagetsi. Humidity sensors inouya muhukuru hwakasiyana uye zvigadziriso; Mamwe akabatanidzwa mumidziyo inobatwa nemaoko, senge ma-smartphones, nepo mamwe akabatanidzwa mumahombe akaiswa masisitimu, akadai semhepo yekutarisa masisitimu. Semuyenzaniso, Hengko tembiricha uye humidity transmitters anoshandiswa zvakanyanya muthemeteorological, zvekurapa, zvemotokari uye HVAC maindasitiri uye maindasitiri ekugadzira. Indasitiri giredhi yakakwira chaiyo humidity sensor inogona kuve nechokwadi kuyerwa kwakaringana mumarudzi ese ehutsinye nharaunda.
Chechitatu, Maverengero Nzira
Humidity sensors inoiswa muhunyoro hunyoro (RH) sensors uye absolute humidity (AH) sensors zvichienderana nenzira inoshandiswa kuverenga humidity. Hunyoro hwehunyoro hunoenderana nekuenzanisa kuverenga kwehunyoro hwenguva chaiyo pane imwe tembiricha ine hunyoro hwepamusoro mumhepo patembiricha iyoyo. Naizvozvo, iyo humidity humidity sensor inofanirwa kuyera tembiricha kuti iverenge hunyoro hunyoro. Absolute humidity, nekusiyana, inotarirwa pasina tembiricha.
Chekutanga, Kushandiswa kweSensors
Temperature sensors dzinenge dzisingaperi zvikumbiro zvekushandisa, sezvo zvichishandiswawo mune dzakasiyana siyana zvigadzirwa zvekurapa, zvinosanganisira magineti resonance imaging (MRI) zvishandiso uye inotakurika ultrasound scanners. Temperature sensors dzinoshandiswa mumidziyo yakasiyana-siyana mudzimba dzedu, kubva kumafiriji nemafiriza kusvika kuzvitofu nemahovhoni kuti ive nechokwadi chekuti zvinodziyirwa kusvika kune tembiricha chaiyo yekubika, zviwitsi zvemhepo/zvidziya. Kunyangwe majaja ebhatiri akajairwa anoashandisa kudzivirira kuwandisa kana kusachajisa bhatiri zvichienderana nekupisa kwaro.
Kunyangwe zvingaite sezvisingaite kuti kubviswa kwemafuta kushandiswe kune tembiricha sensors, iwo akakosha kuti ave nechokwadi chekuchengetedza uye anoshanda maitiro ekubvisa mafuta. Iyo mafuta bhiti ine tembiricha sensor pamagumo ayo inozivisa vashandi kana ichida kumisa kuchera, nekuti kana yanyanya kupisa (nekuti inoramba ichidhirowa zvakadzika pasi), inogona kupisa zvakanyanya uye kutyora.
Iyo tembiricha sensor inovakwa muradiator yemota. Izvi zvakakosha, nekuti kana mvura inotenderera nemuinjini yemotokari ichisvika tembiricha yakakwira isina kuchengetedzeka, vanokuzivisa kuti, kana ikapfuura, inogona kukonzera kutadza kweinjini, pamwe nekudzora mamiriro ekunze emota /. Nekugadzirisa otomatiki parameter zvinoenderana nekupisa, mamiriro aya anodzivirirwa pasina kuisa mutyairi munjodzi.
HVAC masisitimuzvinoda kuyerwa tembiricha kubatsira kuchengetedza tembiricha yakanaka mukamuri kana muchivakwa. Masensa ekupisa anodiwa munenge mune yese air-conditioning unit uye system mudzimba nemumahofisi. Iwo anogona zvakare kushandiswa kuona kuvuza nekuona kusingatarisirwe tembiricha anomalies.
Renewable simba rinotsamira pane tembiricha sensors kuti ishande nemazvo. Solar kupisa pombi, turbines emhepo, biomass combustion application uye pasi kupisa masosi zvese zvinoenderana netembiricha mutemo uye kuyerwa.
Chechishanu, Precision Calibration
Kuti uone kurongeka kweiyo sensor, iyo yakawanikwa yakakosha inofananidzwa neyereferensi chiyero. Kuona chokwadi chehumidity sensors, takagadzira zviyero tichishandisa nzira ye "saturated salt". Muchidimbu, kana mamwe mamunyu (ionic makomisheni akadai setafura munyu kana potassium chloride) akanyungudutswa mumvura, anogadzira mamiriro ehunyoro hunozivikanwa.
Izvimakemikari zvinhuanoshandiswa kugadzira microenvironment ine inozivikanwa muzana yehukama humidity (RH) (iyo referensi standard), iyo inozoverengwa ne sensor. Kunyanya chaizvo, isu tichagadzirira mhinduro mutangi rakavharwa kubata mhepo, uye toisa iyo yakabatana sensor mutangi rakavharwa. Mushure meizvozvo, iyo sensor inoverengwa kakawanda uye maitiro anonyorwa.
Isu tinokwanisa kugadzira maprofiles eiyo sensor pasi pekuyedzwa nekudzokorora maitiro aya nesaiti akati wandei, imwe neimwe inoburitsa hunyoro hwakasiyana. Nekuti isu tinoziva hunyoro hweumwe neumwe microenvironment, tinogona kuenzanisaiyo sensorkuverenga neaya anozivikanwa kukosha kuona chokwadi che sensor.
Kana kutsauka kwakakura asi kusingakundiki, tinogona kuvandudza kurongeka kwechiyero nekushandisa masvomhu ekugadzirisa maitiro musoftware.
