Description

Technical Overview

The Bently Nevada 330500-02-00 Velomitor Piezo-velocity Sensor is a high-performance, industrial-grade vibration sensing solution engineered for continuous machinery health monitoring in demanding rotating equipment applications. Designed for integration into predictive maintenance and condition monitoring systems, this sensor delivers accurate, low-noise velocity measurements across a broad frequency range—ideal for detecting early-stage mechanical faults such as imbalance, misalignment, bearing degradation, and resonance issues. Its ruggedized stainless steel housing and hermetically sealed construction ensure reliable operation in harsh environments, including high humidity, dust, oil mist, and moderate chemical exposure commonly found in power generation, petrochemical, pulp & paper, and heavy manufacturing facilities.

Unlike accelerometers requiring external integration or velocity transducers dependent on active electronics, the 330500-02-00 utilizes a self-generating piezoelectric design that produces a true velocity-proportional output signal (in mV/(in/s) or mV/(mm/s)) without internal amplification or power supply requirements. This passive architecture enhances long-term stability, minimizes failure points, and simplifies system wiring—reducing installation time and lifecycle maintenance costs. The sensor’s optimized mechanical resonance and damping characteristics provide excellent linearity from 4.5 Hz to 1,000 Hz, meeting ISO 10816 and API 670 standards for vibration severity assessment in critical rotating machinery.

Key Features

• True Velocity Output: Self-powered piezoelectric design delivers direct, proportional velocity signals—no external power or signal conditioning required.
• Rugged Industrial Construction: Stainless steel body with integral cable and IP67-rated environmental protection for reliable performance in extreme plant conditions.
• Wide Frequency Response: Linear operation from 4.5 Hz to 1,000 Hz supports comprehensive fault detection—from slow-speed gearmesh issues to high-frequency bearing defects.
• High Sensitivity & Low Noise: Optimized for use with Bently Nevada 3500/42M, System 1®, and other industry-standard monitoring platforms; compatible with standard 10–30 VDC powered signal conditioners.
• Easy Integration & Calibration: Standard 10–32 UNF mounting thread and consistent sensitivity calibration simplify retrofitting and system scalability across fleets of turbines, compressors, motors, and pumps.
