330500-03-02 Bently Nevada Velomitor Piezo-velocity Sensor
Product Overview
The Bently Nevada 330500-03-02 Velomitor Piezo-Velocity Sensor is a high-performance industrial vibration monitoring device designed for casing, bearing housing, and structural vibration measurement in rotating machinery. It belongs to the 330500 Velomitor series, which integrates piezoelectric sensing technology with solid-state electronics to deliver reliable velocity output for critical machinery protection systems.
This sensor is widely used in power generation, oil & gas, and heavy industrial applications where continuous vibration monitoring is essential for equipment reliability and predictive maintenance.
Product Features
The 330500 Velomitor Piezo-Velocity Sensor is a rugged, integrated piezoelectric accelerometer that directly measures absolute vibration velocity. Unlike traditional moving-coil velocity sensors, it features a solid-state design with no moving parts, improving durability and long-term stability.
It is designed for:
- Continuous machinery vibration monitoring
- Bearing housing and casing vibration measurement
- Rotating equipment protection systems
- Predictive maintenance and condition monitoring
Integrated Piezoelectric Technology
The 330500-03-02 sensor uses an advanced piezoelectric crystal with integrated electronics to provide velocity-proportional output, ensuring stable and accurate vibration measurement.
Solid-State Design (No Moving Parts)
Because the 330500 Velomitor sensor has no mechanical moving components, it:
- Eliminates mechanical wear
- Improves long-term reliability
- Reduces maintenance requirements
- Ensures stable signal performance over time
Wide Frequency Response
According to Bently Nevada specifications, the sensor supports a broad frequency range suitable for industrial machinery diagnostics, typically covering low-frequency structural vibration up to high-frequency mechanical faults.
Long-Distance Signal Transmission
The 330500 series supports cable runs up to 305 meters (1,000 ft) while maintaining measurement integrity, making it suitable for large industrial plants.
