Description

The V&F PreSampler is a heated module for preparing engine exhaust gas samples in automotive testing. It contains a heated sample gas pump and a heated inlet pressure regulator (0.8 to 5 bar abs.), with heating up to 200 °C.

An integrated particle filter (0.5 µm ceramic surface filter) can be backflushed into the sample line, with preflush to the analyzer system. The PreSampler is controlled via the AK interface over RS232 or Ethernet, and can also be operated and visualised manually through the WebVision browser interface.

Equipment

  • 1 sample inlet and 1 sample outlet
  • 1 particle filter: 0.5 µm ceramic surface filter
  • 1 filter backflush into the sample line / preflush to the analyzer system
  • 1 heated sample pump
  • 1 heated inlet pressure regulator
  • 2 internal and 2 external heating circuits

Typical applications

  • Development of internal combustion engines (diesel and petrol)
  • Catalyst development
  • Fast measurement of hydrocarbons
  • Ammonia measurements on DeNOx catalysts
  • NOx measurements on diesel engines

Application examples

Automotive industry

  • Ammonia and NOx measurements in engine exhaust gas
