Dust Monitoring | Leak Alert 480

Supplier: Group Instrumentation

The Leak Alert 480 is primarily used to monitor leaks from electrostatic precipitators, warning maintenance teams of reduced performance due to failing plates or chambers leading to increased emissions.

Problems with plate charging voltage and collection efficiency can be detected rapidly and effectively by monitoring changes in particle emissions. In addition, the Leak Alert 480 can be used as a rugged and reliable dust monitor for small and medium sized boiler stacks where instrument approvals may not be necessary.

The Leak Alert 480 continuous particulate monitor uses the Dynamic OpacityTM ratiometric optical measurement principle. This technique monitors the variation in the amount of received light from the light beam transmitted
across the stack. The variation derives from the temporal distribution of particulate which attenuates the light beam. The Leak Alert 480 calculates the dynamic response (ratio of light variation to light intensity or obscuration). This method has the added benefit that the measurement is unaffected by lens contamination. The instrument response is proportional to dust concentration. The Leak Alert 480 provides an indication of increasing dust levels operating in a 0-100% mode, but can be upgraded to include advanced features and user options.
