Triaxial Accelerometer for NVH Applications

The PCB J356B21 is a precision triaxial accelerometer specifically designed for noise, vibration, and harshness testing in automotive and machinery applications. This advanced sensor features three orthogonal piezoelectric sensing elements in a single compact housing, providing simultaneous measurement of vibration in X, Y, and Z directions. The accelerometer offers high sensitivity, wide frequency response, and low noise floor essential for accurate NVH characterization. It incorporates ICP (Integrated Circuit Piezoelectric) signal conditioning, hermetically sealed construction for environmental protection, and standardized mounting interface for versatile installation. The sensor enables comprehensive vibration measurement without requiring three separate accelerometers, simplifying test setup and ensuring proper spatial alignment. This professional-grade instrumentation is essential for vehicle NVH development, machinery condition monitoring, and structural dynamics testing where multi-axis vibration measurement is required for complete characterization of dynamic behavior and noise source identification.
