The BBT 143 Blow-By Test System is a compact measuring system for the determination of the oil droplet content of crankcase gases (blow-by) at engine test rigs.
It combines the precision of a gravimetric measurement of the Gravimetric Measuring System GMS 141 with the time resolution of an optical concentration measurement of the Process Aerosol Photometer PAP 610.
Additionally, the Process Aerosol Photometer PAP 612 provides the opportunity to measure oil films and oil gushes in pipes e.g. at tilt test stands.
Benefits
- time-saving and reproducible determination of oil content in blow-by gases
- measurement in the full flow of the blow-by up to 300 l/min
- compensation of the differential pressure from gravimetric sampling
- high resolution and rapid measurement from optical inline measurements
- integration into engine test stands
Applications
- determination of oil content in blow-by on the engine test stand
- evaluation of oil mist separators on the engine test stand
- on-line concentration monitoring of oil mist aerosols
Accessories
- BBT 143 differential pressure compensation
- GMS 141 flat sheet filters
