The BG-3 is engineered for accuracy! Its superior T-DAC technology (Transient Dilution Airflow Control) allows engine manufacturers to collect extremely accurate data, very quickly. Finally, engine manufacturers can comply with the strict 2007 regulations with accuracy and speed.
Patented T- DAC™ Technology: • Solves the problem of high dilution rates. • Allows the speed of the dilute mass flow controller to correctly correlate the sample flow with the actual engine exhaust mass flow. • Controls the sample mass flow rate in real time, so that the sample mass flow rate is proportional to the exhaust mass flow rate. • Controls the filter temperature, so it does not exceed regulation limits. The BG-3 validates data quality through automated calibration and controlled features. It continuously controls all critical operational and calibration data parameters and readings, making them immediately available to the test- cell engineer. Now, engineers can make decisions during and after a test, saving valuable time and money. • Complete calibration of entire system at initial commissioning • Validation of the system by Sierra with certification documentation • Fully automated daily calibration and calibration verification between each test • Fully automated leak check of the system for the engineer’s convenience • Filter face velocity (sample mass flow rate) for filter size and temperature Auto Zero-Span check • Filter weight calculation sheet for the engineer’s convenience • Zero/span check of the system • Go/no go sample flow check during each test • Measured flow versus set flow check prior to each test The BG-3 is clearly the most accurate choice. Sierra's BG-3 produces the highest possible data quality through sophisticated software and hardware, uses patented components to measure, control, and extract gases from the proprietary dilution tunnel. Make the smart choice. Make the BG-3 choice.
