Features
Application of Prepolarized Free Field Low Noise Measurement Microphone
The prepolarized free-field low-noise microphone features a low noise floor, down to 6.5 dBA, suitable for various measurement scenarios, including low-noise measurement, sound power measurement, and automotive NVH assessment.
Quality and Warranty
The microphone adopts a second-generation alloy diaphragm, high-strength protective grille, and artificial corundum insulator, which makes them stable and reliable measurement microphones on the market. Compared with traditional nickel and stainless steel, alloy diaphragms provide superior corrosion resistance, high temperature stability, impact resistance, and specific strength.
Compatibility
The AWA14411 measurement microphone is compatible with IEPE or conventional preamplifiers from various manufacturers. IEPE is a general-purpose constant current source power supply technology used in preamplifiers.
Calibration
Each measuring microphone is calibrated using traceable calibration equipment at the factory and comes with a calibration certificate. It is recommended to recalibrate at least once a year.
