The Bently Nevada 330400 and 330425 accelerometer datasheet provides specifications, environmental limits, compliance certifications, and ordering information.
These accelerometers are designed for critical machinery applications such as gear‑mesh monitoring, offering high‑range acceleration measurement (50 g for 330400, 75 g for 330425) and robust environmental protection. Installation on bearing housings or machine casings is recommended to ensure accurate vibration data.
The datasheet details electrical parameters, frequency response, temperature sensitivity, power requirements, mechanical dimensions, and hazardous‑area approvals. Ordering options for cables, mounting kits, and accessories are also included.
| Frequency Response | 10 Hz to 15 kHz ±3 dB |
|---|---|
| Temperature Sensitivity | -11% to +3% typical |
