Senther Technology's noise sensor N2250A has attracted widespread attention in the field of acoustic measurement due to its excellent performance and innovative design. The launch of N2250A not only fills the gap in market demand for high-precision and high stability noise sensors, but also injects new vitality into the development of related industries.
As a 1/2-inch free field pre polarized measurement microphone, N2250A is made of titanium alloy and precision stainless steel materials, which have excellent corrosion resistance and robustness, and can maintain high stability in various complex environments. Whether it is harsh outdoor climate conditions or complex indoor electromagnetic environments, it can ensure the accuracy of measurement data.
The research and development team has carried out technical breakthroughs to address the problem of traditional measurement microphones affecting high-frequency sound fields and causing measurement errors in the sound field. N2250A has carefully adjusted the high-frequency frequency response through unique free field compensation technology, effectively compensating for the errors caused by the microphone in the high-frequency sound pressure in the sound field, enabling engineers to accurately measure the undistorted true sound pressure of the microphone before it is placed in the sound field.
In terms of performance parameters, N2250A performs excellently. Its frequency response range reaches 3.15-20kHz (± 2dB), which can cover the frequency range required for the vast majority of acoustic measurement scenarios; The dynamic range is as high as 17-146dB, which can cope with various noise signals ranging from extremely weak to extremely high intensity; The equivalent noise is below 17dB (A), ensuring that clear and accurate data can be obtained even in low-noise environments. In addition, the product fully complies with international and domestic standards such as IEC 61094-4 and GB/T 20441.4-2006, providing strong guarantees for the authority and reliability of measurement results.
N2250A has a wide range of applications. In the research of aviation components, it can accurately capture the noise characteristics of aircraft engines and cabins, providing key data support for aviation noise reduction design; In the field of NVH (noise, vibration, and acoustic roughness) testing, its high stability makes it an indispensable testing tool in the product development process of industries such as automobiles and home appliances; In professional applications such as sound source localization and modal analysis, N2250A also helps engineers quickly and accurately obtain the required information with excellent performance.
In order to better meet the diverse needs of users, the company has also provided a complete measurement system configuration solution for N2250A. Users can flexibly choose accessories such as BNC connector cables, multi-channel IEPE signal conditioners, and data acquisition systems based on their actual usage scenarios. 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.
