The Process Aerosol Photometer PAP 610 was developed from Topas for measurements of mass concentration in blow-by aerosols, where the concentration is determined in-situ. This measuring instrument is an addition to the Gravimetric Measurement System GMS 141 which is also provided by Topas and used for calibrating the PAP 610.
Advantages
- High time-resolution transmittance measurement with 2 wavelengths
- Temperature compensation of electronic assembly
- Simple cleaning of process windows
- Heatable measurement chamber (maximum temperature limited by a safety temperature limiter)
- Seals of FKM/FPM (oil- and temperature-resistant)
- Windows software PAPWin for calibration, configuration and data acquisition
Applications
- Transmittance measurement of oil aerosol for crank case ventilation in combustion engines
- Concentration monitoring of aerosol generators on oil mist test stands (SPT 140)
- In-line monitoring of aerosol separators (oil mist separator testing)
- Monitoring of mean particle size of submicron aerosols
Principle
- A highly concentrated aerosol passes through an extinction of light arrangement and causes a light decrease of the incident light in propagation direction.
- It may be shown that is possible to draw conclusions about the concentration and mean particle size of the aerosol by measuring light decrease for two different wavelengths.
- A direct indicator for the particle size is the extinction ratio.
