FilterSense introduces the PM 100 Multi-Channel Particulate Monitor, an EPA-compliant particulate monitor. The continuous particulate emission monitor and baghouse leak detector incorporates Automatic Zero and Span Checks to eliminate manual calibration audits as required by the US-EPA for MACT and other regulations for fabric filter particulate emissions monitoring. In addition to EPA compliance, benefits include eliminating cleanup costs, preventing the escape of valuable powders and protecting downstream equipment such as blowers and HEPA filters, says the company. The PM 100 offers several levels of particulate monitoring performance based on charge induction and protected-probe technologies invented by FilterSense. As particles flow near and around the probe, a minute current is induced. A DSP processes the signal into an absolute output relative to particulate flow. A protective layer over the probe works in combination with induction-sensing to ensure reliable operation with conductive particulate, moist powders, corrosive gases and particulate buildup. Maintenance is minimal and there is no need for an air purge. For durability, the sensors are passive and free of electronics. The control unit and electronics are remote, says the company, for safe, easy access and to facilitate EPA QA checks.
