SS 823-51

Uniaxial Accelerometer，Structural Acoustic Measurement
SS 823-51 Structure Acoustic Measurement Sensor comprises a high-sensitivity, low-noise accelerometer and a rubber vibration isolation mount. The main body is constructed from high-strength stainless steel, offering exceptional hardness, corrosion resistance, and wear resistance. Characterized by high sensitivity and low noise, and when paired with the rubber isolation mount, it is typically used in automated testing scenarios such as automotive NVH testing, end-of-line testing for motor-based products, and modal testing.

The sensor module of the SS 823-51 is interchangeable with models of different specifications to accommodate a wider range of testing requirements. The rubber vibration isolation mount prevents resonance with mechanical equipment during testing, thereby enabling high-quality, high-bandwidth test results.
