Features GRAS 147EB CCP X-Rugged Microphone Set

147EB is a free-field microphone optimized for wheelhouse brake noise testing in the automotive industry. It is designed to withstand the conditions in the wheelhouse during prolonged testing on public roads in all types of climate and weather. A rugged design that withstands shock and vibrations combined with a three-layer protection system for the diaphragm enables it to be used for realistic testing of brakes on proving grounds and public roads. The two protective grids and the customized windscreen are easily replaceable consumables. With the 147EB it is now no longer necessary to use sub-standard microphones and cumbersome customized protection for acoustic road testing of brakes - it is now possible to measure without compromising data quality using a high-quality IEC 61672 class 2 microphones.
