BBT 143 Blow-By Oil Content Measurement System
Compact measurement system for determining oil-droplet content in crankcase blow-by gas at engine test rigs, combining gravimetric sampling with fast optical concentration measurement.
Model Overview
| Model | System role | Primary measurements | Standards / application fit |
|---|---|---|---|
| BBT 143 | Blow-by oil-content measurement system | Gravimetric oil-mass determination with time-resolved optical concentration monitoring | Engine blow-by measurement and oil-mist separator evaluation |
Key Features
Combined measurement principles
Uses gravimetric measurement for accuracy and optical photometry for high time resolution.
Full-flow capability
Measures blow-by streams at flow rates up to 300 L/min.
Differential-pressure compensation
Optional compensation supports representative gravimetric sampling.
Rapid inline response
Optical measurement tracks transient changes in oil-mist concentration.
Engine-test integration
The compact system is designed for connection to engine development test stands.
Separator performance evaluation
Supports assessment of oil-mist separator behaviour under realistic blow-by conditions.
