Unlike Triboelectric systems, the Electodynamic measurement is not significantly affected by velocity variation between 8m/s and 20m/s and is not effected by build up on the rod surface. The system has suitable resolution for Baghouse applications (>0.1 mg/m3).
 
 
 
The BBS220 Bagfilter monitoring system is suitable for filter failure detection in single or multi-compartment filter systems. The functionality of baghouse filters can be controlled and maintained to operate at optimum levels. Having the capability to identify the bagfilter or compartment in which the suspect fabric filter is fitted, down time and costs for replacing non-faulty bags are significantly reduced. Over time, analysis of the baghouse functionality and filter deterioration can be assessed such that maintenance can be scheduled for natural shutdowns or when the process is least affected. In addition, from a regulatory perspective, prediction of faulty fabric filters can mean few or no excursions over emissions levels.
 
* Detects and identifies the specific bagfilter or compartment with broken bags
* Permits comparison of filter conditions on multiple outlets
* Identification of suspect filter and indication of severity of problem minimizes
   down-time and reduces costs
* Effective predictive maintenance capability by overseeing and predicting problems before
   they occur
* Assists in maintenance scheduling both for rework and in budgeting for replacement
   parts
* Provides accurate records for regulatory purposes
 
 
 		 
 
 
The BBS220 combines advanced signal processing techniques with PCME's unique Electodynamic measurement principle. When the sensing probe is installed in the duct or stack, particles in the airstream interact with the sensing rod and charge induction effect is analyzed in the probe. Distributions in the particle stream result in a frequency charge induction response, which is directly proportional to the concentration of particulate (application dependent). The sensors' output is an analysis of this frequency response. Emissions are monitored and displayed to the nearest 5% of a programmable alarm level which is easily set to relative to normal bagfilter emission levels.
