Particulate CEM (continuous emissions monitor) meets environmental regulations such as US-EPA MACT and other standards like ASTM D22 for monitoring particulate emissions from fabric filter baghouses, cartridge type dust collectors, cyclones, and some ESPs (electrostatic precipitators). Particulate levels down to at least 0.1mg/m3 can be monitored. The company’s non-optical, charge induction-sensing, and protected-probe technologies are said to ensure reliable measurements in all types of tough environments, including cement, power, steel, carbon black, asphalt plants, incinerator’s, lead smelters, chemical and pharmaceutical dryers. The system features the latest in DSP technology for advanced signal analysis and automatic self checks to meet required EPA instruments standards. The device also is stated to offer lower-level monitoring and higher accuracy than opacity meters with less maintenance and a simpler installation. FilterSense, (+1) 978-927-4304; www.filtersense.com
