CRYSOUND POCKET Acoustic Imaging Camera Now Available on Kickstarter.
CRY3203-S01 Free-Field Microphone Set, 1/2", 50mV/Pa
The CRY3203-S01 is a free-field prepolarized measurement microphone and preamplifier set widely used in acoustic test environments such as anechoic chambers and quiet rooms.
Its frequency response covers the audible range of human hearing, making it particularly well suited for noise measurement and detection. In addition, it is widely used in electroacoustic testing, audio measurement, and acoustic research, supporting a broad range of precision acoustic measurement applications.
Product Highlights
High-Precision Free-Field Measurement for Everyday Applications
Featuring a 1/2-inch free-field prepolarized design, the CRY3203-S01 delivers stable and repeatable results across a wide range of common acoustic measurement tasks. It is well suited for applications including acoustic R&D validation, quality inspection, noise monitoring, acoustic metrology, and automotive NVH testing.
Balanced Performance for General Acoustic Applications
With a sensitivity of 50 mV/Pa, a frequency response of 3.15 Hz to 20 kHz, and a dynamic range of 16 dBA to 138 dB, the CRY3203-S01 provides an excellent balance of sensitivity, bandwidth, and measurement headroom. This allows it to maintain strong signal-to-noise performance across a variety of general-purpose acoustic tests while accommodating both fine detail capture and high-SPL conditions.
Easy Integration into Test Systems
Its prepolarized design supports IEPE powering, BNC connectivity, and IEEE 1451.4 TEDS, enabling fast and efficient integration into modern data acquisition and analysis systems. This translates into simpler setup, higher deployment efficiency, and greater flexibility for rapid switching between laboratory and field environments.
