In the field of acoustic measurement, accurately capturing the essence of sound is a challenging task. Acoustic engineers often face the dilemma of how to minimize the interference of equipment on the sound field during the measurement process, in order to obtain truly distortion free acoustic data? The N2250A 1/2 inch free field pre polarized measurement microphone launched by SenseTime Technology is an innovative product designed to address the pain points in this industry.

Professional design, breaking through measurement limitations

N2250A is made of titanium alloy and precision stainless steel materials, which not only have corrosion resistance and structural robustness, but also maintain excellent stability in the environment. The core innovation of this microphone lies in its unique free field compensation technology - by carefully adjusting the high-frequency frequency response, it effectively compensates for the errors caused by the microphone to high-frequency sound pressure in the sound field, enabling engineers to accurately measure the true sound pressure of the microphone before it is placed in the sound field.

Performance meets stringent requirements

Technical specifications of N2250A: The frequency response range reaches 3.15-20kHz (± 2dB), the dynamic range is as high as 17-146dB, and the equivalent noise is below 17dB (A). These parameters enable it to cope with various acoustic measurement scenarios ranging from extremely weak to strong. The product complies with international and domestic standards such as IEC 61094-4 and GB/T 20441.4-2006, ensuring the reliability and reliability of measurement results.

Multi domain application, showcasing professional value

In the research of aviation components, N2250A, with its wide frequency response and low noise characteristics, can accurately capture the noise characteristics of aircraft engines and cabins, providing key data for noise reduction design. In the field of NVH (Noise, Vibration, and Acoustic Roughness) testing, the high stability of this product makes it an ideal choice for research and development in industries such as automotive and home appliances. In addition, N2250A also performs well in professional applications such as sound source localization and modal analysis.

Complete solution, simplify workflow

Senser Technology provides a complete measurement system configuration solution for N2250A, including optional accessories such as BNC connector cables, multi-channel IEPE signal conditioners, and data acquisition systems. Users can flexibly choose according to their actual needs, among which the standard model N2250A adopts IEPE output, and there is also a version that supports TEDS function to choose from. This modular design greatly simplifies the system integration process and improves work efficiency.

Acoustic measurement tools for the future

With the advancement of Industry 4.0 and intelligent manufacturing, the requirements for accuracy and reliability of acoustic measurements are becoming increasingly high. The N2250A free field measurement microphone, with its innovative design concept and performance, is becoming a powerful assistant for acoustic engineers. Whether in product development, quality control, or fault diagnosis, this product can provide users with reliable measurement data, helping enterprises achieve precise optimization of acoustic performance.

Senser Technology will continue to delve into the field of acoustic measurement, based on innovative products such as N2250A, to provide customers with more comprehensive acoustic measurement solutions and explore the infinite possibilities of the sound world together.
