Description

Technical Overview

The Bently Nevada 330500-00-04 Piezo-Velocity Sensor is a high-performance, ruggedized transducer engineered for continuous, real-time vibration monitoring in mission-critical industrial rotating equipment. Designed for integration into comprehensive machinery protection systems—including Bently Nevada’s System 1® and 3500 Monitoring Systems—the sensor delivers exceptional signal fidelity across a broad frequency range (typically 4.5 Hz to 1,000 Hz), enabling accurate detection of early-stage mechanical faults such as imbalance, misalignment, bearing degradation, and resonance conditions. Its piezoelectric sensing element ensures stable output without external power, eliminating loop-powered dependencies and reducing system complexity.

Manufactured to stringent IEC 61266-1 and ISO 10816 compliance standards, the 330500-00-04 excels in harsh operational environments—including high ambient temperatures (up to +121°C), corrosive atmospheres, and high EMI zones—thanks to its hermetically sealed stainless steel housing and integrated integral cable with high-temperature polyimide insulation. The sensor’s low-noise design and optimized damping characteristics minimize phase shift and amplitude distortion, supporting reliable trend analysis and automated alarm generation in predictive maintenance programs across oil & gas, power generation, petrochemical, and heavy manufacturing facilities.

Key Features

• Piezoelectric velocity output – Self-generating, no external power required; delivers true RMS velocity signals compliant with ISO 10816 vibration severity standards
• Ruggedized industrial construction – 316 stainless steel housing with IP67-rated sealing and high-temperature cable (rated to +121°C)
