The DustAlarm ES and DustTrend ES series (photo) of broken-bag detectors and dust-emission trend-monitoring systems are now available with hazardous-location approvals. The devices feature intrinsically safe probes for ultimate hazardous-location protection. These monitors provide repeatability that is not affected by variations in relative humidity, process temperature or pressure. These units are appropriate for monitoring the level of dust emissions in dust-collection system exhausts in any location where such information is critical to safety, maintenance, equipment operation, plant efficiency, employee welfare and the environment. The monitors can be connected with the free DustConfig software to set custom alarm points, view live activity within the duct, or review data history for up to a 24-h period. — Monitor Technologies LLC, Elburn, Ill.
