Bently Nevada 330500-06-00 Velomitor

Quick Overview

The 330500-06-00 is a high-performance Velomitor Piezoelectric Velocity Sensor. Unlike traditional moving-coil sensors, this solid-state device uses integrated electronics to measure absolute vibration on bearing housings or casings. It is a industry standard for monitoring balance and general machine health in power plants and refineries.

Technical Data

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) $\pm$5%

• Frequency Response: 4.5 Hz to 5 kHz ($\pm$3 dB)

• Velocity Range: 1270 mm/s peak (50 in/s)

• Operating Temp: -55°C to +121°C

• Housing Material: 316L Stainless Steel

• Mounting Thread: 5/8-18 UNF (Option 06)

Key Features

• Solid-State Design: No moving parts to wear out, ensuring a significantly longer service life than mechanical velocity pickups.

• Omni-Directional: Can be mounted at any angle (vertical, horizontal, or inverted) without affecting accuracy.

• Hermetically Sealed: The 316L stainless steel housing is laser-welded to protect internal electronics from moisture and corrosive industrial chemicals.

• Wide Frequency Range: Capable of capturing both low-frequency unbalance and higher-frequency mechanical faults.
