Applications of AWA14424C Measuring Microphone
This sensor has a wide measurement frequency range, with a lower frequency limit down to 0.2 Hz, making it suitable for various measurement scenarios, including infrasound measurement, sonic boom measurement, and other applications. It is also widely used in acoustic research and electroacoustic testing.
Quality and Warranty
The measuring microphones utilize a second-generation alloy diaphragm, a high-strength protective grid, and a synthetic corundum insulator, making them stable and reliable measurement microphones on the market. Compared to traditional nickel and stainless steel, the alloy diaphragm offers superior corrosion resistance, high-temperature stability, shock resistance, and specific strength.
Compatibility
The AWA14424C 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 at the factory using traceable calibration equipment and comes with a calibration certificate. Recalibration at least annually is recommended.
