GENERAL
SET/TSH 2 thiab SET/TSH2 yog capacitive qib detectors rau cov kua.
V-versions yog siv nrog cov kua ua kua los qhia tias qis lossis qib siab, lossis rau example roj/dej interface nyob rau hauv ib tug roj separator. Oversions yooj yim rau siv nrog cov kua uas tsis muaj hluav taws xob, xws li roj, qhia tias qib qis lossis siab.
SET/TSH 2 yog ib tug generic sensor thiab nws suits rau feem ntau daim ntaub ntawv.
SET/TSH 2 yog qhov tseem ceeb tib lub sensor nrog rab rawg li counterelectrode. Nws yog tsim rau ntau qhov chaw nyuaj, xws li roj, roj hnyav lossis cov kua dej txhaws. Cov sensors yog cov cuab yeej ntawm cov cuab yeej pab pawg II, qeb 1 G thiab tuaj yeem ntsia tau rau hauv Cheeb Tsam 0/1/2 qhov chaw txaus ntshai.

CONNECTIONS THIAB INSTALLATION
Lub sensor yog nruab nrog ib tug shielded 3-xaim cable. Cov 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 Kev Txhim Kho thiab Kev Ua Haujlwm ntawm chav tswj.
Lub sensor 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 ua rau lub tswb nrov thaum nws qhov ntsuas qhov ntsuas yog ib nrab rau hauv cov kua ntsuas. Lub sensor tuaj yeem ntsia tau los ntawm kev dai rau ntawm nws cov cable los ntawm lub tank qab nthab lossis nws tuaj yeem kho tau hauv nws qhov chaw nrog cov yeeb nkab txuas nrog ¾ "hauv xov. Lub mounting ruaj ruaj tiv thaiv kev txav ntawm lub sensor thaum muaj ntws hauv lub tank.
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; IEC / EN 60079-25 Cov khoom siv hluav taws xob rau cov huab cua uas muaj peev xwm tawg tau - Intrinsically ruaj ntseg hluav taws xob system "i", IEC / EN 60079-14 Cov khoom siv hluav taws xob rau cov pa cua tawg.

KHO TSHUAJ TIV THAIV
- Raus lub sensor rau hauv cov kua yuav tsum tau ntsuas kom lub sensing ntsiab ntawm SET/TSH(S) 2-O/V sensor yog ib nrab-immersed nyob rau hauv cov kua (lub teflon coated pas nrig ua raws li lub sensing caij) raws li nyob rau hauv daim duab. 4.
- Tig lub rhiab heev trimmer ntawm Labkotec SET tswj chav kom lub tswb coj cia li mus.
- Txheeb xyuas qhov ua haujlwm los ntawm kev nqa thiab muab tso rau hauv lub sensor ob peb zaug rau hauv cov kua.
Txheeb xyuas cov Lus Qhia Kev Txhim Kho thiab Kev Ua Haujlwm ntawm chav tswj yog tias muaj cov lus qhia tshwj xeeb rau daim ntawv thov tshwj xeeb.

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 hauv tshooj 5. Kev Pabcuam thiab Kho yuav tsum tau ua raws. Xyuas kom tseeb tias Fault-led, uas qhia txog kev ua haujlwm tsis zoo, tsis nyob rau. Yog tias
Fault-led yog nyob rau, kho tej kev puas tsuaj los yog luv luv Circuit Court nyob rau hauv hluav taws xob Circuit Court.
Koj tuaj yeem tshawb xyuas qhov ua haujlwm ntawm lub sensor los ntawm kev ntsuas nws cov khoom siv voltage (V) thiab tam sim no noj (I) siv lub multimeter.
Ntsuas voltage ntawm kev tswj chav tsev txuas + thiab -. Lub voltage yuav tsum yog 10.5…12 VDC.
Txuas mA-gauge rau lub sensor Circuit Court raws li daim duab hauv qab no los ntawm kev sib txuas ntawm cov hlau tsis muaj. 1 los ntawm chav tswj.

| sensor nkaus rau hauv dej | 10… 12 mA | 10,5… 12,5 mA |
Kev Pabcuam thiab Kho
Lub sensor 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.
