Engineered for improved performance, the new BetaGuard PM 3.0™ represents the latest advancement in system design. New advanced hardware features and completely redesigned system control software are based on over two million operating hours and over 10 years’ experience continuously monitoring particulate emissions from a variety of plant stacks across the country.
More alarm points are now watched. Daily calibrations of the mass and flow measurement are now faster leading to more data availability. ACA and SVA results are stored in the PLC memory for electronic retrieval. The faster processor in the ControlLogix PLC has increased the accuracy and repeatability of all timing sequences within the monitor’s operating system leading to more stable beta attenuation measurements. The new PLC and system program increases the monitor’s accuracy, reliability, and operability.
Teflon coated nozzles and a Teflon coated sample cone are new features. The Teflon coated nozzle reduces particulate deposition and loss in the sample probe. Field trials demonstrated much less scaling of particulate on the interior walls of the nozzle. The Teflon coated sample cone eliminates buildup of the filter paper on the ring forming the seal to the filter. Both hardware features have reduced maintenance.
The new BetaGuard PM 3.0 provides what you are looking for in a superior source particulate monitor.
