330500-02-00

• Uses an internal electronic integrator instead of moving coils to eliminate mechanical wear under continuous vibration
• Electron-beam welded 316L stainless steel enclosure prevents oil or moisture penetration and shields against RFI/EMI
• Operates from 4.5 Hz to 5.0 kHz to detect both low-frequency unbalance and high-frequency bearing faults

Bently Nevada™ Velomitor Piezo-velocity Sensors are designed to measure absolute (relative to free space) bearing housing, casing, or structural vibration. The 330500 is a specialized piezoelectric accelerometer that incorporates embedded integrated electronics in a solid-state design. Because the 330500 incorporates solid-state electronics and has no moving parts, it does not suffer from mechanical degradation and wear, and can be mounted vertically, horizontally, or at any other angle of orientation.

The 330500 series delivers industry-leading accuracy by integrating an accelerometer and an electronic integrator inside a single, ruggedized housing. This unique design eliminates the moving parts found in conventional mechanical velocity sensors, resulting in near-zero friction wear and an exponentially longer service lifespan. It provides an output voltage that is directly proportional to the machine’s vibration velocity, feeding clean data into monitoring systems like the Bently Nevada 3500 series or standard industrial PLC/DCS networks without requiring external signal conversion modules.

Crafted from premium-grade 316L stainless steel, the 330500-02-00 housing is fully hermetically sealed using advanced electron-beam welding techniques. This heavy-duty enclosure ensures total immunity against moisture, dust, chemical vapors, and oil penetration. It also features superior electrical isolation and extreme resistance to Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI), guaranteeing high-signal integrity even when installed adjacent to massive high-voltage electric motors or variable frequency drives (VFDs).
