FW300 Ex
|
|
| |
Laser Transmissiometer for Dust Measurements Sticky dusts, high gas temperatures or varying gas velocities - the FW300 measures also under unfavorable condistions instantanous and with high presicion.
Its version with pressurized housing suits for hazardous areas zone 1 and 2 and its version with dust-proof housing for hazardous areas zone 22. |
|
|
Applications The FW300 is suitable for measurement of dust concentrations in processes or of dust emission in mill works as well as for monitoring of dust loads in factory halls.
It is used for emission monitoring and monitoring of filter plants in energy production, in the building material industry, metallurgy, food and feed stuff industrie and the chemical industry.
