          防爆ATEX/IECEx外殼中
           AT-2000 ATEX/IECEx系列批準的Magnehelic差壓表防爆外殼,將使用范圍擴展到危險場所。該壓力計可指示正、負或壓差,精度在2%以內。
           
          安裝的重要注意事項:
          電纜必須通過1/2“NPT電纜密封套或ATEX/IECEx導管安裝(不隨儀表提供)。確保布線后關閉密封蓋和電纜密封套,以保持IP66等級。僅在儀器斷電后打開蓋子。?注意:檢查設備和手冊上的本地安全規則和警告,以便在危險區域正確使用儀器。?產品應用?風扇和鼓風機壓力過濾電阻空氣速度通風液位帶氣泡器系統流體放大器或射流系統中的壓力?特性?ATEX/IECEx外殼提供所有Magnehelic在防火防爆外殼中的性能和價值?對壓力變化的快速響應意味著在評估危急情況時毫不拖延?耐用堅固的外殼和高質量的組件結合在一起提供了較長的使用壽命和最小化的停機時間?高沖擊強度和高溫額定應用存在危險環境的地方
