Chii chinonzi VOC gasi?
VOC ipfupiso yemakemikari anoshanduka-shanduka eorganic. Mupfungwa yakajairika, VOC inoreva simba remakemikari anoshanduka-shanduka eorganic; Zvisinei, maererano nekuchengetedzwa kwezvakatipoteredza, inoreva boka remakemikari anoshanduka-shanduka eorganic anoshanda uye anokuvadza. Zvikamu zvikuru zveVOC zvinosanganisira mahydrocarbon, halogenated hydrocarbons, oxygen hydrocarbons, uye nitrogen hydrocarbons, kusanganisira benzene series compounds, organic chloride, fluorine series, organic ketones, amines, alcohols, ethers, esters, acids, uye petroleum hydrocarbons. Uye boka remakemikari anotyisidzira hutano hwevanhu.

Chii chinonzi PID detector?
Kuona Photoionization (PID) kunoshandisa mwaranzi ye ultraviolet inogadzirwa ne ionization yegasi risina simba nemagetsi ane frequency yakawanda kuti ionise mamorekuru egasi ari kuyedzwa. Nekuyera simba remagetsi rinogadzirwa negasi rine ionized, huwandu hwegasi riri kuyedzwa hunowanikwa. Mushure mekuonekwa, maion anobatanazve mugasi rekutanga neutsi, zvichiita kuti PID ive detector isingaparadze.
Sensor yePID yakagadzirwa yega
Munda wemagetsi unoshamisa
Hupenyu hurefu
Kushandisa nzira yekuchenjera yekumutsa simba remagetsi, zvichiwedzera hupenyu hwemasensa (hupenyu hwese anopfuura makore matatu)
Tekinoroji yekuvhara yazvino
Kuvimbika kwakanyanya
Hwindo rekuvharira rinoshandisa magnesium fluoride pamwe chete nemaitiro matsva ekuvharira, zvichidzivirira kubuda kwegasi kusingawanzoitiki uye zvichiita kuti sensor irambe ichishanda kwenguva refu.
Mhete yekuunganidza gasi pahwindo
Kunzwa kwakanyanya uye kurongeka kwakanaka
Pane rin'i yekuunganidza gasi pahwindo remwenje weUV, izvo zvinoita kuti ionization yegasi ive yakanyatsojeka uye kuti kuonekwa kwayo kuve nyore uye kwakarurama.
Zvinhu zveTeflon
Kuramba ngura uye kugadzikana kwakasimba
Zvikamu zvinovhenekerwa nemwenje ye ultraviolet zvese zvakagadzirwa nezvinhu zveTeflon, izvo zvine simba guru rekudzivirira ngura uye zvinogona kunonotsa oxidation ne ultraviolet ne ozone.
Chimiro chitsva chekamuri
Kuzvichenesa uye kuzvigadzirisa hakuna muripo
Rudzi rutsva rwekugadzira chimiro chekamuri rine dhizaini yekuwedzera flow channel mukati me sensor, iyo inogona kuputitsa nekuchenesa sensor zvakananga, zvichideredza tsvina iri pachubhu yerambi uye kuita sensor isina kugadzirisa
Chinoongorora pombi chakagadzirirwa sensor itsva yePID chinoita kuti sensor ishande zvakanaka, ichipa mhedzisiro iri nani yekuona uye ruzivo rwuri nani rwemushandisi
Hunhu hwekudzivirira ngura hunosvika kuWF2 uye hunogona kuchinjika munzvimbo dzakasiyana-siyana dzine hunyoro hwakawanda uye munyu wakawanda wekupfapfaidza (Kupfapfaidza pendi yefluorocarbon inodzivirira ngura paganda)
Zvakanakira 1: Hapana maaramu enhema munzvimbo dzine tembiricha yakakwira uye hunyoro
Kuedza uku kwakatevedzera kuyedza kwekuenzanisa pakati pema detector echinyakare ePID nema detector ePID maviri munzvimbo ine hunyoro hwakawanda hwe55°C. Zvinogona kuonekwa kuti ma detector echinyakare ePID ane shanduko huru mukuwanda kwesimba munzvimbo iyi uye anowanzo sangana nealarms dzenhema. Uye Anxin patented dual sensor PID detector haichinji-chinji uye yakagadzikana zvikuru.
Kubatsira 2: Kugara kwenguva refu uye kuchengetedza pasina
Sensor itsva yePID
kutarisa kwakabatana
Kusefa kwezvikamu zvakawanda
Tsvaga sensor yePID inogara kwenguva inopfuura makore matatu uye isingagadziriswi muhupenyu hwayo hwese.
Kubudirira kwakakosha kwakafanana nehupenyu hwema sensors e catalytic
Chakanakira 3: Dhizaini yemodular, kuisa nekugadzirisa zviri nyore
PID sensor module, inogona kuvhurwa nekukasira uye kuparadzaniswa kuti igadziriswe
Pombi yemodular, inokurumidza kuvharwa nekutsiviwa
Module yega yega yakawana dhizaini yemodular, uye zvikamu zvese zvisingakuvadzi uye zvinogoneka kushandiswa zvakatsiviwa nekukurumidza uye zviri nyore.
Kuedza kwekuenzanisa, kuenzanisa kwakakwirira nekwakaderera
Kuenzanisa nePID sensor brands dzakatorwa dzisina kurapwa
Kuenzanisa kuyedza nerudzi rwezvioni zviri pamusika

Nezve mibvunzo ine PID detectors?
Mhinduro: Chigadzirwa chakatangwa panguva ino chinonyanya kutsiva sensor yePID yakagadzirwa nekambani yedu, iyo yakachinja chimiro chekamuri remhepo (dhizaini yenzira yekuyerera) uye modhi yekupa magetsi. Dhizaini yenzira yekuyerera inogona kuderedza kusvibiswa kwechiedza uye kupukuta machubhu emwenje asingabhadharwe kuburikidza nekusefa kwemazinga akawanda. Nekuda kwemodhi yemagetsi inopindirana yakavakirwa mukati me sensor, kushanda kwepakati nepakati kwakapfava uye kwakangwara, uye kuona pamwe chete nemasensa maviri kunoita kuti hupenyu huve hwemakore anopfuura matatu.
Mhinduro: Mabasa makuru ebhokisi remvura nderekudzivirira mvura yemvura uye utsi hwemaindasitiri kuti husakanganisa zvakananga mudziyo wekuongorora. 2. Kudzivirira kukanganiswa kwenzvimbo dzinopisa zvakanyanya uye hunyoro pamidziyo yekuongorora yePID. 3. Kuvhara guruva mumhepo uye kunonotsa hupenyu hwesefa. Zvichibva pazvikonzero zviri pamusoro apa, takaisa bhokisi rinodzivirira mvura sezvinodiwa. Ehe, kuwedzera bhokisi rinodzivirira mvura hakuzove nekukanganisa kukuru panguva yekupindura kwegasi.
Mhinduro: Zvinofanira kucherechedzwa kuti makore matatu ekuchengetedza pasina zvinoreva kuti sensor haifanirwe kugadziriswa, uye firita ichiri kuda kugadziriswa. Tinokurudzira kuti nguva yekuchengetedza firita inowanzo kuve mwedzi 6-12 (inopfupikiswa kusvika kumwedzi mitatu munzvimbo dzakaoma dzezvakatipoteredza)
Mhinduro: Pasina kushandisa ma sensor maviri ekuona majoini, sensor yedu itsva inogona kurarama kwemakore maviri, nekuda kwe sensor yedu itsva yePID (tekinoroji ine patent, musimboti mukuru unogona kuonekwa muchikamu chechipiri). Maitiro ekushanda ekuona majoini e semiconductor+PID anogona kurarama makore matatu pasina matambudziko.
Mhinduro: a. Isobutene ine simba shoma reionization, ine Io ye9.24V. Inogona kuiswa ionization nemwenje yeUV pa9.8eV, 10.6eV, kana 11.7eV. b. Isobutene ine chepfu shoma uye gasi patembiricha yemumba. Segasi re calibration, harikuvadzi hutano hwevanhu zvakanyanya. c. Mutengo wakaderera, uri nyore kuwana
Mhinduro: Haizokuvadzwi, asi kuwanda kwegasi reVOC kunogona kukonzera kuti gasi reVOC rinamire pahwindo neelectrode kwenguva pfupi, zvichikonzera kuti sensor isashande kana kuti isanzwe zvakanyanya. Zvakakosha kuchenesa rambi reUV neelectrode nemethanol nekukasika. Kana paine gasi reVOC rinogara kwenguva refu richipfuura 1000PPM panzvimbo yacho, kushandisa PID sensors hakudhuri uye ma non dispersive infrared sensors anofanira kushandiswa.
Mhinduro: Chisarudzo chikuru chinogona kuitwa nePID i 0.1ppm isobutene, uye sensor yePID yakanakisisa inogona kuita 10ppb isobutene.
Kusimba kwechiedza cheultraviolet. Kana chiedza cheultraviolet chakasimba, pachava nemamorekuru egasi akawanda anogona kuiswa maion, uye resolution yacho ichave iri nani.
Nzvimbo inopenya yerambi reultraviolet nenzvimbo yepamusoro peelectrode inounganidza. Nzvimbo huru inopenya nenzvimbo huru yeelectrode inounganidza zvinongoerekana zvaita kuti pave nekupenya kwakanyanya.
Kushanda kwemagetsi epreamplifier. Kushanda kwemagetsi epreamplifier kudiki, kusimba kwemagetsi anoonekwa. Kana kusimba kwemagetsi e operating amplifier kuri kukuru, chiratidzo chemagetsi chinobatsira chisina simba chichanyudzwa zvachose mukushanda kwemagetsi, uye resolution yakanaka haigone kuwanikwa yega.
Kuchena kwebhodhi redunhu. Maseketi eanalog anosungirirwa pamabhodhi edunhu, uye kana paine kubuda kwakawanda kwemvura pabhodhi redunhu, magetsi asina simba haagone kuonekwa.
Hukuru hwekuramba kuripo pakati pemagetsi nemagetsi. Sensor yePID inzvimbo inoburitsa magetsi, uye magetsi anogona kungowedzerwa nekuyerwa semagetsi kuburikidza ne resistor. Kana simba remagetsi riri diki zvakanyanya, shanduko diki dzemagetsi hadzigone kuwanikwa dzega.
Kugadziriswa kweADC yeanalog-to-digital converter. Kugadziriswa kweADC kwakakwira, chiratidzo chemagetsi chinogona kugadziriswa chidiki, uye kugadziriswa kwePID kuri nani.
