GENERAL
SET/OS2 yog qhov ntsuas ntsuas rau qib siab, qib qis thiab piv txwv li kev kuaj pom.
Cov ntawv thov raug siv yog cov roj cais thiab cov roj twj uas cov roj / dej cuam tshuam lossis dej / huab cua cuam tshuam yuav tsum tau kuaj pom.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm SET / OS2 sensor yog capacitive thiab nws tuaj yeem txuas nrog Labkotec SET-series tswj units.
SET/OS2 yog ib qho cuab yeej ntawm cov cuab yeej cuab tam II, qeb 1 G. Lub sensor tuaj yeem ntsia tau rau hauv cheeb tsam 0/1/2 muaj kev phom sij.
CONNECTIONS THIAB INSTALLATION
SET/OS2 yog nruab nrog ib tug shielded 3-xaim cable. Cov xov hlau 1 thiab 2 yuav tsum txuas nrog cov khoom sib txuas (1 = +, 2 = -) hauv chav tswj. Hlau 3 yuav tsum txuas mus rau hauv av equipotential ua ke nrog cov ntaub thaiv npog ntawm lub cable. Thov xa mus rau cov lus qhia installation ntawm chav tswj.
Lub cable tuaj yeem luv luv lossis, thaum lub chaw tswj hwm nyob deb ntawm lub sensor, lub cable tuaj yeem txuas nrog lub thawv sib txuas. Lub sensor tuaj yeem ntsia tau los dai rau saum huab cua los ntawm lub tank sab saum toj los tsim kom muaj lub suab nrov nrov lossis tso rau hauv cov kua kom tsim tau cov qib qis lossis roj / dej tswb.
Thaum txhim kho lub sensor rau hauv qhov chaw muaj kev puas tsuaj tawg (0/1/2), cov qauv hauv qab no yuav tsum tau ua raws; TS EN IEC 6007925 Cov khoom siv hluav taws xob rau cov huab cua uas muaj peev xwm tawg tau - Intrinsically muaj kev nyab xeeb hluav taws xob system "i", EN IEC 60079-14 Hluav taws xob
apparatus rau explosive gas atmospheres.
Lub sensor yuav tsum tsis txhob muab ntsia rau hauv qhov chaw uas cov vapor, roj lossis kua, xws li cov ntxhiab tsw thiab chlorinated hydrocarbons lossis muaj zog alkalis lossis acids, tuaj yeem ua rau cov khoom puas.
KHO TSHUAJ TIV THAIV
- Tig lub SENSE trimmer ntawm chav tswj mus rau qhov kawg clockwise txoj hauj lwm.
- Tso lub sensor rau hauv cov kua kom ntsuas. Thaum 30-40 hli ntawm lub sensor yog immersed nyob rau hauv cov kua, chav tswj yuav tsum ua hauj lwm. Yog tias nws tsis yog, kho qhov SENSE trimmer maj mam counterclockwise kom txog thaum qhov xav tau hloov pauv mus txog. Raws li rau cov kua dej conductive (dej thiab lwm yam), qhov hloov pauv yuav tsum tau ua tiav thaum 10-20 hli ntawm lub sensor yog raus.
- Txheeb xyuas qhov ua haujlwm los ntawm kev nqa thiab muab tso rau hauv lub sensor ob peb zaug rau hauv cov kua.
Yog lub sensor tsis ua haujlwm
Yog tias lub sensor nyob hauv thaj chaw muaj kev phom sij yuav tsum tau siv Exi-classified multimeter thiab Ex-standards tau hais nyob rau hauv tshooj 4. Kev Pabcuam thiab Kho yuav tsum tau ua raws.
Xyuas kom tseeb tias lub sensor raug txuas nrog rau chav tswj. Lub voltage ntawm connectors 1 thiab 2 hauv chav tswj yuav tsum yog 10,5…12V.
Yog voltage yog qhov tseeb, ntsuas qhov ntsuas tam sim no raws li hauv qab no:
- Txuas lub ampere 'meter' raws li daim duab hauv qab no los ntawm kev txiav cov kab hluav taws xob 1 ntawm lub hauv paus.
- Ntsuas qhov tam sim no.
Sensor tam sim no nyob rau hauv ntau yam xwm txheej:
| Version O (Code = SE6311) | |
| huv thiab qhuav sensor hauv huab cua | 5… 7 mA |
| sensor nkaus hauv roj (εr ≈ 2) | 9… 11 mA |
| sensor nkaus hauv dej | 12… 16 mA |
| Version V (Code = SE6312) | |
| huv thiab qhuav sensor hauv huab cua | 5… 6 mA |
| sensor nkaus hauv dej | 12… 16 mA |
Kev Pabcuam thiab Kho
Cov sensors yuav tsum tau muab ntxuav thiab kuaj txhua lub sijhawm thaum tshem lub tank lossis cais tawm thiab thaum ua haujlwm txhua xyoo. Txhawm rau ntxuav, siv cov tshuaj ntxuav me me (xws li cov kua ntxhua khaub ncaws) thiab txhuam txhuam.
Kev pabcuam, tshuaj xyuas thiab kho Ex-apparatus yuav tsum ua raws li cov qauv EN IEC 60079-17 thiab EN IEC 60079-19.
