SS 825-51
- Structural Acoustics Measurement Sensor
The SS 825-51 Structural Acoustics Measurement Sensor consists of a high-sensitivity, low-noise accelerometer and a rubber vibration isolation mount. The main body is made of high-strength stainless steel, offering excellent hardness, corrosion resistance, and wear resistance. The sensor features high sensitivity and low noise. When used with the rubber vibration isolation mount, it is typically applied in automated testing scenarios such as automotive NVH testing, motor end-of-line testing, and modal analysis.
The sensor portion of the SS 825-51 can also be detached and used separately, while the rubber vibration isolation mount helps prevent resonance with mechanical equipment during testing.
