Preamp-integrated microphone TYPE 4158N (TYPE 1)
The frequency range is 20Hz to 100kHz. It is a microphone suitable for ultrasonic measurements.
TYPE4158N is a free-field type 1/4 inch microphone with a frequency range of 20Hz to 100kHz. The sound pressure sensitivity, including the preamplifier, is -50dB±3dB re 1V/Pa (3.2mV/Pa). Due to its compact size, it is less affected by reflections and diffraction, making it suitable for measuring high sound pressure levels with a sensitivity of 3.2mV/Pa. As it is IEPE compatible, it can be directly connected to an FFT analyzer or AD converter that provides constant current supply. 【Features】 ■ Can be directly connected to analyzers such as FFT analyzers using a BNC cable ■ Enables high-precision measurements at a low cost ■ Achieves long-term stability through forced aging at high temperatures of 360℃ *For more details, please refer to the external link page or feel free to contact us.
