Hauv cov chaw ua haujlwm txaus ntshai uas cov roj av, cov pa dej thiab cov hmoov av uas yooj yim hlawv ua rau muaj kev pheej hmoo tawg tas li, cov cabling uas muaj kev nyab xeeb (IS) sawv cev rau kev tswj hwm kev nyab xeeb tseem ceeb rau cov cuab yeej siv hluav taws xob tsawg, kev sib txuas lus thiab kev tswj hwm. Tsis zoo li cov cables dav dav, cov cables uas muaj kev nyab xeeb yog tsim los txwv kev tso tawm hluav taws xob hauv qab ob qho tib si kev ua haujlwm ib txwm thiab qhov xwm txheej tsis zoo, tshem tawm cov khoom siv hluav taws xob uas tuaj yeem ua rau muaj kev kub ntxhov.

Cov xov hlau uas muaj kev nyab xeeb yuav tsum yog xim xiav (RAL 5015) raws li IEC 60079-14 rau kev txheeb xyuas thaj chaw txaus ntshai.
Cov xim uas yuav tsum tau ua no tso cai rau cov kws hluav taws xob kom paub qhov txawv ntawm IS circuits thiab cov xov hluav taws xob uas tsis yog IS, tiv thaiv kev sib txuas tsis raug ntawm lub zog txaus ntshai.
Kawm cov kev cai thiab cov kev zam.

Ib txoj hlua hluav taws xob muaj kev nyab xeeb (IS) yog tsim los nqa lub zog hluav taws xob tsawg uas tsis tuaj yeem ua rau muaj kev kub hnyiab hauv huab cua tawg.

Tsis zoo li cov xov hluav taws xob uas tsis tawg uas muaj cov khoom tawg, cov xov hluav taws xob IS tiv thaiv cov hluav taws xob tag nrho. Kawm txog cov lus txhais ntawm IS cable, cov kev cai tsim kho, cov xim xiav ntawm lub plhaub, thiab cov kev cai ntawm IEC 60079-11.

Ib txoj hlua hluav taws xob uas muaj kev nyab xeeb tsis tuaj yeem tsim lossis khaws cia lub zog hluav taws xob txaus kom ua rau muaj kev kub hnyiab hauv huab cua tawg. Kawm txog lub ntsiab lus, yuav ua li cas cov teeb meem txwv tsis pub muaj zog ua haujlwm, vim li cas lub peev xwm qis (C) thiab qis inductance (L) tseem ceeb, thiab vim li cas cov lej xim xiav thiaj li xav tau thoob ntiaj teb rau kev teeb tsa thaj chaw muaj kev phom sij.

Ib txoj hlua ntsuas Intrinsically Safe (IS) txwv lub zog hluav taws xob kom tiv thaiv kev tawg hauv thaj chaw txaus ntshai. Tsis zoo li cov qauv tsim uas tsis tawg (Ex-d) uas muaj kev tawg, cov hlua IS tiv thaiv kev kub hnyiab los ntawm kev tswj lub zog hluav taws xob / tam sim no. Kawm txog cov hnab xiav, cov kev cai tiv thaiv, thiab cov yam ntxwv ntawm IEC 60079-11.

Cov xov hlau Intrinsically Safe (IS) txwv lub zog hluav taws xob kom tiv thaiv kev kub hnyiab hauv cov huab cua khawb av tawg. Lawv muaj cov yam ntxwv tswj tau capacitance/inductance nrog cov xim xiav-xiav raws li IEC 60079-11, cov kev xaiv tiv thaiv Ex-ia/Ex-ib, thiab cov qauv tsim cov xov hlau sensor yooj ywm rau kev nyab xeeb hauv av khawb av.

Cov xov hlau tiaj tiaj (ribbon/FFC) yog cov khoom sib dhos uas txuag chaw, ntau tus neeg txuas hluav taws xob zoo tagnrho rau kev ua haujlwm robotics thiab automation. Lawv muaj FEP rwb thaiv tsev (-90°C txog +200°C), cov kev xaiv conductor (CU/TC/SPC/NPC), thiab kev tiv thaiv uas muaj ntaub thaiv lossis tsis muaj ntaub thaiv. Phau ntawv qhia no qhia txog kev xa cov ntaub ntawv ceev ceev, cov txiaj ntsig ntawm kev tsim qauv me me, thiab cov qauv xaiv rau kev siv robotics uas xav tau ntau.

Tsis yog, RS485 thiab CAT6 tsis zoo ib yam. RS485 cables yog tsim los rau kev sib txuas lus hauv kev lag luam ntev (1,200m) nrog 120Ω impedance rau Modbus RTU networks. CAT6 cables yog tsim los rau kev sib txuas lus ceev ceev Ethernet (100m, 100Ω impedance) hauv chaw ua haujlwm / LAN ib puag ncig. Phau ntawv qhia no piv 12+ cov kev ntsuas tseem ceeb los pab cov engineers teev kom raug.

Cov xov hlau RS485 thiab Ethernet ua haujlwm sib txawv hauv kev sib txuas lus hauv kev lag luam. Phau ntawv qhia no piv lawv cov lus qhia, cov kev cai tiv thaiv, thiab cov ntawv thov zoo tshaj plaws los pab koj xaiv qhov yog.

Tshawb nrhiav vim li cas RS485 cov kab hluav taws xob yog cov thawj coj ua lag luam hauv kev lag luam automation. Kawm txog impedance (120Ω), cov ntaub ntawv shielding, thiab yuav ua li cas xaiv qhov gauge zoo rau Modbus thiab CANopen systems.
