The Bently Nevada 330500-02-04 is a high-performance Velomitor Piezo-Velocity Sensor designed to measure absolute vibration on bearing housings, casings, or structural components. Unlike traditional moving-coil velocity transducers, this unit utilizes a specialized piezoelectric accelerometer design with integrated solid-state electronics, ensuring long-term reliability and immunity to mechanical wear.

Features

• Solid-state design with no moving parts for extended service life.
• Capable of mounting in any orientation (horizontal, vertical, or angled).
• Incorporates embedded electronics for direct velocity output.
• Rugged construction suitable for harsh industrial environments.
• Includes M8 x 1 mounting thread adapter.

Applications

• Machine condition monitoring for rolling-element bearing machines.
• Detection of imbalance and misalignment in rotating equipment.
• Vibration monitoring for motors, pumps, fans, and compressors.
• Critical infrastructure in oil and gas, petrochemical, and power generation sectors.

Technical Specifications

Installation Guidelines

• Surface Preparation: Ensure the mounting surface is flat, clean, and free of debris to ensure accurate vibration transmission.
• Torque Specification: Do not exceed the maximum tightening torque of 46 kg-cm (40 in-lb) during installation.
• Orientation: The sensor is omnidirectional; it may be mounted at any angle required for the application.
• Cabling: Supports cable runs up to 305 meters (1,000 feet) without significant signal degradation.
• Handling: As a precision instrument, avoid dropping or subjecting the sensor to high-impact shocks.
