3<\/sup>) as well as different volume flows in order to characterize them clearly regarding its separation behaviour. Modifications of the characteristics of the separator which are caused by e. g. the change of the volume flow, the temperature, the loading of the filter etc. must be clearly determined by a reliable online measurement or an in-situ measurement. In order to prevent condensation effects but also evaporation effects, the complete aerosol guidance with the HMT 1000 P including preparation, sampling and measuring volume is heatable up to 120 \u00b0C. Thus, an isothermal fractional separation efficiency determination is guaranteed.
\n<\/b><\/p>\nWhy regulation of \u00b1 200 mbar?<\/b><\/p>\n
Depending on the structure of the oil separator an over pressure or under pressure developes at the entrance of the filter. Because of the control of \u00b1 200 mbar at the entrance of the test device oil mist separators can be tested under the same conditions as in practice.<\/p>\n
Isothermal in-situ measurement, e. g. at the engine<\/b><\/p>\n
The testing system HMT 1000 is built up movably and modularly. Thus, the single components can be used also for other tests and particle measurements, e. g. in-situ measurements at the engine.<\/p>\n
