The Bently Nevada 330505-02-02-02 Low Frequency Velocity Sensor is to measure and monitor low-frequency vibration velocity in rotating and reciprocating machinery for condition monitoring and predictive maintenance. It converts mechanical vibration into proportional electrical signals, enabling accurate detection of early-stage mechanical issues such as imbalance, misalignment, looseness, or bearing faults. This helps improve equipment reliability, prevent unexpected failures, and support continuous machinery health assessment in industrial environments.
The core parameters of the Bently Nevada 330505-02-02-02 Low Frequency Velocity Sensor include a sensitivity of 20 mV/mm/s (508 mV/in/s) with ±10% tolerance, a frequency response range of 0.5–1000 Hz (±3 dB) and a more precise band of 1–200 Hz (±0.9 dB), a peak velocity measurement capability up to 102 mm/s (4 in/s), and amplitude linearity within ±3% across the operating range. Electrically, it operates with a bias voltage of –12 ±1 VDC, provides insulation resistance of at least 120 MΩ at 500 VDC, and withstands dielectric strength up to 600 VRMS at 50 Hz for 1 minute. Additional characteristics include a low noise floor of 3 µm/s RMS at 100 Hz and a typical cable capacitance of 45 pF/m, ensuring stable and accurate vibration signal transmission in industrial monitoring applications.
The Bently Nevada 330505-02-02-02 Low Frequency Velocity Sensor is a precision industrial vibration monitoring device designed for reliable measurement of low-frequency mechanical vibrations in critical rotating machinery. It features a compact design with a 90° ±5° mounting angle and an M8×1 adapter, allowing easy installation in space-constrained environments while ensuring accurate alignment. Engineered for condition monitoring and predictive maintenance systems, it provides stable and high-sensitivity velocity output signals that support early detection of mechanical faults and help improve equipment reliability. With robust electrical characteristics, a wide operational frequency range, and strong resistance to electrical noise and environmental interference, the sensor delivers consistent performance in demanding industrial applications such as turbines, motors, pumps, and other rotating equipment.
