哪裡生產礦用煙霧傳感器?
技術參數
1.防爆型式 礦用本質安全型 2.防爆標誌為:ExibⅠ3.外殼防護等級:IP54
6.工作電流:≤80mA;7.動作條件:≥0.1mg/m3;
8.輸出信號:當無煙狀態下或煙霧濃度<0.1mg/m3時,傳感器輸出高電平信號≥11VDC;當煙霧濃度≥0.1mg/m3時,輸出低電平信號≤0.5VDC。
9.動作靈敏度為Ⅱ級,響應時間≤30s。
10.傳輸距離:傳感器到關聯設備之間的傳輸介質為礦用移動輕型橡套軟電纜MYQ3×1.5mm2 接線,與主機的電纜長度≤1000m。
用途
GQQ0.1礦用煙霧傳感器為礦用本質安全型,用於監測煤礦井下機械故障磨擦、電纜發熱、煤層自燃等原因引起的火災事故。可安裝在煤礦井下的帶式輸送機機旁易發熱處,作為礦用帶式輸送機保護裝置的煙霧保護信號檢測之用。
characteristics
Small volume, light weight, easy to install a suspension of rings, sensor installation, deb ing and maintenance convenient and reliable. This sensor by gas sensitive type probe element, sensitive, reliable, and correct action, when measured smoke concentration was 0.1 mg/m3 time output low level signal to realize belt conveyor smoke protection.
