Description

The 330500-00-04 is a Bently Nevada Velomitor Piezo-velocity Sensor configured with Option 00 (no mounting adapter) and Option 04 (CSA and ATEX multiple agency approvals). This sensor is engineered for measuring absolute casing, bearing housing, or structural vibration on rotating machinery. As a specialized piezoelectric accelerometer with integrated solid-state electronics, the unit converts velocity-based vibration into a proportional voltage signal for direct interface with monitoring systems.

By incorporating integrated electronics with no moving parts, the 330500 eliminates the risk of mechanical degradation common in traditional velocity transducers. This specific configuration supports installation across multiple hazardous area environments (CSA/ATEX) and is designed for direct mounting without an adapter, allowing for versatile horizontal, vertical, or angular orientation.

Features

Option 00: No mounting thread adapter included (standard 3/8-24 UNF integral mount).
Option 04: CSA/ATEX multiple hazardous area approvals for safe operation in specified zones.
Integrated solid-state piezoelectric design provides superior durability and frequency response.
316L stainless steel, hermetically sealed case for resistance to industrial environmental conditions.
Case-isolated grounding prevents ground loops and electrical interference.
Compatible with standard Bently Nevada 3300 monitoring systems for casing vibration protection.

Applications

Absolute vibration monitoring on bearing housings and machine casings.
Structural vibration measurement in power generation and petrochemical facilities.
Rotating machinery protection where machine casing vibration is a key indicator of rotor or internal component condition.
Hazardous area machinery monitoring (Class I, Div 1; ATEX/IECEx zones).

Installation Guidelines

Ensure the sensor is installed on a clean, flat surface on the bearing housing or machine casing for optimal frequency response.
Improper mounting can attenuate amplitude and frequency performance or generate false signals.
Use appropriate Bently Nevada interconnect cables (e.g., 9571-NN or 89477-NN) for signal transmission to the monitoring rack.
Ensure hazardous area installation adheres to the safety drawings and entity parameters provided in the datasheet for CSA/ATEX compliance.

FAQ

What does the 04 option code indicate for the 330500-00-04?

The 04 option code indicates that this sensor is configured with multiple hazardous area agency approvals, specifically CSA and ATEX, allowing for use in designated hazardous environments.

Does this sensor include a mounting adapter?

No, the 00 option code in the first segment indicates that this unit does not come with a mounting thread adapter; it is intended for direct mounting using its integral 3/8-24 UNF thread or specific machinery interface.

What is the primary function of the 330500 Velomitor?

The 330500 Velomitor is a piezo-velocity sensor designed to measure absolute casing, bearing housing, and structural vibration, providing a voltage output proportional to velocity for machine protection systems.

Can this sensor be mounted in any orientation?

Yes, because the Velomitor sensor utilizes solid-state piezoelectric technology with no moving parts, it can be mounted vertically, horizontally, or at any other angle without degrading performance.
