Features
Application of pre polarized pressure field broadband high sound pressure measurement microphone
The pre polarized pressure field broadband high sound pressure microphone has a wide measurement frequency range and a high dynamic upper limit, making it very suitable for fields such as high sound pressure testing, ultrasonic testing, noise source localization, and equipment acoustic performance testing.
Quality and Warranty
The microphones utilize a second-generation alloy diaphragm, high-strength protective grille, and synthetic corundum insulator, making them stable and reliable measurement microphones on the market.
Compatibility
The AWA14436 measuring 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.
