Quick Detail

Description

The 330500-02-01 Velomitor Piezo-Velocity Sensor from Bently Nevada is a premium-grade, industrially hardened transducer designed for precise and reliable measurement of absolute casing or structural vibration. As a core component of predictive maintenance and machinery health monitoring systems, this piezo-velocity sensor directly converts mechanical vibration into a highly accurate, low-noise electrical velocity signal, providing critical data for assessing the operational condition of a vast array of industrial assets. Unlike displacement probes that measure relative motion, the Velomitor sensor provides a true velocity output referenced to free space, making it the ideal solution for monitoring non-rotating elements like bearing housings, gearboxes, pumps, and turbine casings where direct shaft observation is impractical.

This specific model is engineered for versatile and robust deployment. It features a standard overall case length of approximately 2.75 inches and is constructed with a durable stainless steel case, ensuring long-term integrity in demanding environments. The sensor includes an M8 x 1 mounting thread adaptor for secure and standardized installation on a variety of equipment surfaces. With a streamlined form factor measuring 7.0x2.3x2.0cm and a lightweight design of 0.14kg, this velocity sensor can be easily integrated into space-constrained locations on both large and small machinery. Its solid-state, piezoelectric sensing element contains no moving coils or delicate internal mechanisms, resulting in exceptional durability, immunity to wear, and consistent performance over an extended service life with minimal maintenance requirements.

Applications

The sensor is ideally suited for broad-based condition monitoring of industrial motors, pumps, fans, and compressors. Its true velocity output and wide frequency response provide an excellent overall picture of machine health, effectively detecting common faults like imbalance, misalignment, bearing defects, and structural resonance in general manufacturing, HVAC systems, and water treatment plants.

With its robust stainless steel construction and extreme operating temperature range (-55°C to 121°C), this sensor excels in harsh and outdoor environments. It is perfectly deployed on critical equipment in refineries, chemical plants, and offshore platforms, where it can withstand exposure to moisture, corrosive agents, and wide thermal swings while delivering reliable vibration data for predictive maintenance programs.

The sensor's compact dimensions and standard M8 mounting thread make it an excellent choice for monitoring small-to-medium sized assets or for adding vibration points to dense machinery skids. It is commonly used on auxiliary drives, conveyor systems, mixers, and packaged equipment where space is limited, providing a high-fidelity velocity signal without requiring extensive installation space or complex setup.

Specifications

Competitive Advantage

1. Solid-State Reliability for Maintenance-Free Operation

Utilizing a rugged piezoelectric sensing element with no moving coils or delicate internal mechanisms, this sensor is inherently immune to the wear and degradation that plague traditional coil-based velocity transducers. This solid-state design guarantees consistent, long-term performance with virtually zero maintenance, significantly reducing lifecycle costs and eliminating a common source of measurement drift.

2. Exceptional Diagnostic Accuracy Across a Broad Spectrum

The sensor provides highly precise vibration data with a calibrated sensitivity of 3.94 mV/mm/s ±5% and excellent amplitude linearity (±2%). This accuracy, combined with its wide velocity range up to 1270 mm/s peak, enables it to capture everything from subtle incipient faults to severe vibration events, providing reliable data for both early warning alerts and detailed diagnostic analysis.

3. Unmatched Durability in Extreme Environments

Housed in a stainless steel case and built to operate across an expansive temperature range of -55°C to 121°C, the Velomitor is engineered for survival in the toughest conditions. It resists corrosion, moisture, and physical impact, ensuring dependable operation in applications ranging from freezing outdoor installations to high-temperature processes near turbines or ovens.

4. Certified Versatility for Global Industrial Deployment

Carrying CSA/US/C agency approvals, this sensor meets key regional safety and performance standards, simplifying procurement and specification for global projects. Its standardized M8 mounting thread and compact form factor allow for flexible and easy integration into both new installations and existing monitoring systems across diverse industries.
