INTRINSIC SAFETY DUST MONITOR For Detection of leakage of dust collector and bag filter breakage Enclosure Concentration measurement range Ex ib ⅡB T4 (Intrinsic safety) 0mg/㎥～1000mg/㎥ Gas flow rate 4.0 m/s or greater Output signal 4 to 20 mADC (500Ω) Contact output 2 NONC contact for upper limit alarm, 1 NONC contact for fault alarm Dust Monitor continuously measures for 24 h the dust in exhaust gas at the secondary side of a dust collector or the like and outputs the alarm contact at the abnormal condition and monitors the relative variation of dust amount with an analog signal. The intrinsic safety enclosure enables it to be used in the hazardous area: Zone 1 & 2. ,Matsushima Measure Tech,POWDER MEASUREMENT > DUST MONITOR >INTRINSIC SAFETY DUST MONITOR
