Application
The gas sampling pre-filters series are used for continuous extractive gas analysis. They serve for precisely representative sampling of sample gas with dust loads above 3g/m3. Typical applications are process monitoring and process optimization, e.g. in coal silos or cement plants.
Technology
The sinter metal filters cover a temperature range of up to 600°C. By choosing an appropriate extension tube the position of the pre-filter in the process can exactly be determined. At the risk of abrasion (erosion of filter material by dust particles with high speed) and also for lifetime extension (deflection of dust particles) an appropriate deflector can be used. The pre-filter has a G3/4“-male thread. The extension pipe selected shall have an R3/4 "male thread connection to the female thread in the sample gas inlet of the gas sampling probes and a G3/4“-female thread for mounting the pre-filter.
Functions
Due to filtration at the surface of the gas sampling pre-filters with increasing operation time a steadily growing dust layer (filter cake) is building up and acting as an additional filtration layer.Moreover, it prevents a deep infiltration of dust particles into the sinter metal filter and thus has a service life-prolonging effect.
