The D.E.M. constantly monitors, measures and cheeks the dust emissions from your facilities. This is a dust emission monitoring device which operates on the triboelectric principle : the airborne particles generate static electricity as they strike the measuring probe, thereby inducing a weak but measurable current, the more numerous the particles, the stronger the current.
The D.E.M. is generally fitted in chimneys downstream from the dust filters.
The preventive control of the quality of the filtration system allows :
- The possible derating of the fan located downstream of the dust collector (ATEX directive)
- The quality control of the air reintroduced into work areas and buildings
- The follow-up of possible drift allowing to anticipate a failure (with regard to the regulatory control according - February 2, 1998)
