Industrial Proximity Probe System – Model 330902-04-40-10-02-CN

1. Brand Identification

This product belongs to a high-reliability industrial condition monitoring and machinery protection ecosystem widely used in rotating equipment applications.

It is commonly associated with Bently Nevada, a leading name in vibration analysis, shaft displacement measurement, and predictive maintenance technologies.

2. Product Series Overview

The model 330902-04-40-10-02-CN is part of the 3300 XL 8mm Proximity Probe Series.

This series is designed for:

• Non-contact displacement measurement using eddy current technology
• Continuous vibration and shaft position monitoring
• High-temperature and high-vibration industrial environments
• Integration into machinery protection systems

Typical system configuration includes:

• Proximity probe
• Extension cable
• Signal conditioning driver (Proximitor type)

3. Product Overview

This model is a precision eddy current proximity probe used to measure the distance between the probe tip and a conductive rotating target, typically a shaft.

The system converts mechanical displacement into an electrical signal proportional to vibration or position change.

The “04-40-10” configuration generally indicates a specific calibration, sensitivity, or mechanical variant within the same probe family, optimized for particular installation or measurement conditions.

The “CN” suffix often refers to a regional or customized configuration specification.

4. Operating Principle

The probe operates using eddy current sensing technology:

• A high-frequency electromagnetic field is generated at the probe tip
• A conductive target induces eddy currents
• Changes in impedance are detected and converted into voltage output
• Output signal corresponds to real-time displacement

Key advantages of this principle:

• No physical contact with rotating parts
• No mechanical wear
• High stability over long-term operation
• Excellent response to micro-vibration changes
