Kangmei venhimna leh venhimna hi khawi hmunah pawh a pawimawh hle. Kangmei leh puak theihna hmun hlauhawm takah chuan an pawimawh hle. Hetiang a nih chuan, . Intrinsic Safety a ni fire detector leh intrinsic safety barrier te hian hlawkna nasa tak a nei a ni. Heng special system te hi kangmei leh puak thei tur venna atana siam a ni. Chu chu detector system-a electrical leh thermal energy tihtlem hmangin an ti thei a ni.

nIntrinsically safe fire detector hi gas puak thei emaw, kang thei thil emaw awmna hmun hlauhawmah chuan himna atana pawimawh tak a ni.
nHetiang specialized equipment chi hian electric heating energy output kha khauh taka tihtlem hmangin ignition hazards awm thei chu a bulpui berah a ti bo a ni.
nPetrochemicals, damdawi siamna, leh thil hlauhawm dahkhawmna hmuna risk sang tak takah chuan he technology hi thlak danglam theih a ni lo.
nIntrinsic safety sensor chi hrang hrangte ziarang leh hman theih tur scenario thiam hi kangmei venna system dik tak siamna atana thil pawimawh tak a ni.
nInternational organization hrang hrangin an certified detector te safety performance leh operational stability te chu Atex a ni official taka finfiah a ni tawh bawk.
Engtin nge intrinsic safety fire detector hian hna a thawh?
nOil leh gas, chemical, leh buhfai siamna hmun, kang thei leh puak thei hmunah te chuan traditional fire detector te hian electric sparks emaw surface overheating emaw a siam theih avangin himna atana hlauhawm a siam a, intrinsic safety (IS) detector te erawh chuan special design hmangin hmun hlauhawmah him taka hnathawh a tichiang thung.
nA technology bulpui ber chu energy limitation mechanism-ah a awm a: circuit chhunga current leh heat energy dik taka control-na hmangin, eng hnathawhna hmunah pawh hmanrua chuan ignition spark emaw, temperature sang hlauhawm tak emaw a siam lo tih a tichiang a ni. He thil tum tihlawhtling tur hian system-ah hian safety barrier - alarm controller leh IS hmanrua inkara component pawimawh tak dah a ngai a, chu chuan energy transmission tam lutuk chu tha takin a block thei a, circuit power chu safety threshold hnuaiah engtik lai pawhin a vawng reng thei bawk.
nHe dual protection design (internal energy limitation+external safety barrier) hian IS detector hi high-risk area-a kangmei enkawlna solution rintlak ber a siam a, chutih rualin international explosion-proof standard ATEX ang chi te pawh a tlin bawk.
UK-a intrinsic safety fire detector hman dan leh standard zawm dan
UK-ah chuan hmun hlauhawma kangmei laka himna hmanrua hman dan tur dan khauh tak a awm a. Heng dan zawm hi dan anga tih tur mai ni lovin, mipui himna leh hnathawh dan mumal tak neih theihna tura pawimawh tak a ni.
Rules set pawimawh tak pakhat chu... Atex Dan siam a ni. Heng dante hi EU thupek atanga lak chhuah a ni a, hei hian puak thei hmuna hmanraw hman tur safety standards inremtir tumna a ni.
ATEX dan siam hi puak thei hmuna himna hmanrua siamtu, hralh leh hmangtu tan chuan a pawimawh hle. European Union chhunga hmun hlauhawm (UK pawh tel)-ah chuan hmanrua leh venhimna system zawng zawngte chu ATEX dan zawm vek tur a ni.
Nihphung pangngai | Hrilhfiahna |
ATEX Directive 2014/34/EU hmanga siam a ni | Hei hian puak thei hmuna hmanraw leh invenna hmanrua te a huam a ni. |
IEC 60079 a ni | Bomb puak thei hmuna electrical hmanrua him taka design, dah leh hman dan tur international rules set. |
Heng dante hriatthiam leh zawm hi a pawimawh hle. Hei hian hmun hlauhawma intrinsic safety fire detector hman hunah himna a awm theih nan a pui a ni.
Intrinsic safety barrier dik tak thlang rawh
Keini Beijing Pinghe hian barrier supplier quality sang tak kan nih angin development plan kan nei a, chu chu barrier physical size tihtlem te, a rit lo leh hman awlsam zawka siam te, installation awlsam zawka siam te, a chhiat theihna tur tihtlem te, leh process system atana hman tlak tak tak barrier te siam te a ni.
Kan PHD-11TN-11 leh PHD-22TN-1111 te hi smoke detector nena hman tur bik atana siam a ni.
Flame leh smoke detector-te signal input chu isolated safety barrier a ni a, hei hian hmun hlauhawma flame detector-te chu isolation power a pe thei a ni. Flame detector te hian 0-40mA signal an siam a, chu chu hmun hlauhawm atanga isolated niin hmun him lamah an thawn chhuak a, smoke alarm-ah hian chanvo a nei a ni. He product hi output circuit hmanga powered a ni a, loop powered DCS/PLC system atan a tha hle.
He product hian independent power supply a mamawh lo va, input leh output terminal te pawh isolated a ni.
