Heated and filtered sampling


The V&F PreSampler is a heated module for sample preparation of engine exhaust gases in the automotive sector. A heated sample gas pump and a heated inlet pressure regulator (0.8 to 5 bar abs.) are installed in the PreSampler with heating up to 200°C. The PreSampler is equipped with an integrated particle filter.

In addition, the PreSampler has an integrated particle filter (0.5μm ceramic surface filter) with a filter backflush into the sample line/preflush to the analyzer system.

The PreSampler is controlled via an AK interface using RS232 or Ethernet.
