Applications of Prepolarized Pressure Field Measurement Microphones
Prepolarized pressure field microphones have a wide measurement frequency range and are designed specifically for precision cavity measurements, widely used in acoustic research and electroacoustic testing.
Quality and Warranty
The microphones utilize second-generation alloy diaphragms, high-strength protective grilles, and synthetic corundum insulators, making them stable and reliable measurement microphones on the market. Compared to traditional nickel and stainless steel, alloy diaphragms offer superior corrosion resistance, high-temperature stability, shock resistance, and specific strength.
Compatibility
The AWA14426 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 measurement microphone is calibrated at the factory using traceable calibration equipment and comes with a calibration certificate. Recalibration is recommended at least annually.
