Quick Detail

Description

The 330500-06-02 Velomitor Piezo-velocity Sensor from Bently Nevada is a high-precision industrial vibration sensor engineered for measuring absolute velocity in bearings, casings, and structural components. Utilizing piezoelectric technology with integrated solid-state electronics, this sensor provides highly reliable, drift-free vibration measurements without moving parts, eliminating mechanical wear over time. Constructed with a 316L stainless steel hermetically sealed case, the Velomitor is resistant to harsh industrial environments, including extreme temperatures from -55°C to 121°C (-67°F to 250°F) and full relative humidity exposure. It features a 5/8-18 UNF mounting thread adaptor, allowing versatile installation angles—vertical, horizontal, or otherwise—while maintaining consistent sensitivity of 0.005 in/s/mstrain. The sensor exhibits amplitude linearity of ±2% up to 152 mm/s (6 in/s) peak and dynamic output impedance below 2400 Ω, ensuring accurate velocity readings across a wide frequency spectrum. Magnetic field susceptibility is limited to less than 51 min/s/gauss (50 gauss, 50–60 Hz), and the sensor survives shock loads up to 5,000 g peak. Case isolation and controlled mounting torque (32–46 kg·cm, 24–40 in·lb) prevent grounding and mechanical errors. Certified for ATEX hazardous-area use, the 330500 Velomitor provides precise, durable, and versatile vibration measurement solutions suitable for modern automated monitoring and predictive maintenance systems.

Applications

1. Bearing Vibration Monitoring
Measures absolute velocity of fluid-film and rolling-element bearings in turbines, compressors, and motors, providing real-time data to detect imbalance or misalignment.

2. Structural Vibration Analysis
Used to monitor casings, gearboxes, and structural components, helping engineers identify resonance or excessive vibration affecting system reliability.

3. Predictive Maintenance in Rotating Machinery
Integrates with automated monitoring systems to detect early signs of wear or imbalance, enabling predictive maintenance scheduling and reducing unplanned downtime.

4. Hazardous Area Machinery Monitoring
ATEX certification allows safe operation in flammable and explosive environments such as petrochemical plants and offshore platforms while maintaining measurement integrity.

5. Shock and Harsh Environment Sensing
Designed to survive shocks up to 5,000 g and extreme temperatures, suitable for heavy-duty industrial applications including aerospace, mining, and power generation equipment.
