IP67 Certification Furthermore, the 146AE is certified water and dust-proof (IP67). Typical Applications and Use The 146AE is a free-field microphone set designed for use in rough conditions such as NVH testing in the automotive industry. It is specifically designed for applications such as: • Engine noise vibration testing • Acoustic performance testing • Pass by noise testing • Power train induced noise • Computer Model Validation/CAE...

GRAS 146AE 1/2'' CCP Free-field Rugged Microphone Set • The ruggedness of the basic microphone set is further enhanced by the replaceable, special shock absorbing protection grid with an integrated filter that protects against oil, moisture, dirt and high-velocity particles. Replaceable Grid with Enhanced Protection Shock Protection The 146AE has a two-stage shock protection system. A special built-in shock absorber prevents minor and medium shock impacts from damaging the microphone. If subjected to a high impact shock, the protection grid will absorb the shock by deforming. The grid is...

GRAS 146AE 1/2'' CCP Free-field Rugged Microphone Set Electronic Data Sheets you will be able to read and write data like properties and calibration data. System Verification The integrated PowerOn indication and the functionality of TEDS are very useful to determine which microphone is connected to which input channel. However, it is not a check of whether the microphone is within specifications or not. For daily verification and check of your measurement setup, we recommend using a sound source like the GRAS 42AG Multifunction Sound Calibrator with the calibration adapter that is part...
