Bently Nevada Accelerometer | 330425-01-00

Quick Overview

The 330425-01-00 is a rugged High-Precision Accelerometer designed for measuring vibration in the $10\text{ Hz}$ to $15\text{ kHz}$ range. This sensor excels at detecting high-frequency faults such as gear mesh problems or early-stage bearing failure. Its compact, hermetically sealed design makes it the go-to choice for monitoring critical machinery in extreme industrial environments.

Technical Data

• Sensitivity: $10.2\text{ mV/m/s}^2$ ($100\text{ mV/g}$) $\pm 5\%$

• Frequency Response: $10\text{ Hz}$ to $15\text{ kHz}$ ($600$ to $900,000\text{ cpm}$)

• Acceleration Range: $490\text{ m/s}^2$ ($50\text{ g}$) peak

• Noise Floor: $0.039\text{ m/s}^2$ ($0.004\text{ g}$) RMS

• Operating Temp: $-55^\circ\text{C}$ to $+121^\circ\text{C}$

• Mounting Thread: $1/4-28$ UNF (Option 01)

Key Features

• Broad Frequency Coverage: Ideal for monitoring high-speed machinery where vibration occurs at very high frequencies.

• Superior Durability: Capable of surviving shocks up to $5000\text{ g}$, ensuring it stays operational even during sudden impacts.

• Clean Signal: A very low noise floor allows for the detection of subtle vibration changes in low-amplitude scenarios.

• Environmentally Hardened: Hermetically sealed against $100\%$ condensing humidity and features low susceptibility to magnetic interference.

• Flexible Installation: Supports cable runs up to $305\text{ meters}$ ($1000\text{ ft}$) without signal loss.
