Bently Nevada 330500-01-05 Velomitor Velocity Sensor

Quick Overview

The 330500-01-05 is a rugged Velomitor Velocity Sensor designed for measuring absolute vibration on rotating machinery casings. Using piezoelectric technology, it provides a superior lifespan compared to older moving-coil sensors. It is a critical component for monitoring general machine health in oil, gas, and power generation sectors.

Technical Data

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

• Frequency Range: 4.5 Hz to 5 kHz ($\pm$3.0 dB)

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

• Operating Temp: -55°C to +121°C

• Housing: 316L Stainless Steel (Hermetically Sealed)

• Mounting Thread: 1/2-20 UNF (Option 01)

Key Features

• Zero Maintenance: The solid-state design has no internal moving parts, eliminating wear-and-tear issues common in mechanical sensors.

• Global Safety: The 05 option provides Multiple Approvals (ATEX, IECEx, CSA), making it safe for use in hazardous (explosive) environments worldwide.

• Orientation Independent: Can be mounted at any orientation without a loss in accuracy or performance.

• Corrosion Resistant: The 316L stainless steel body is built to withstand extreme humidity and chemical exposure.
