Product Overview

The 330104-00-03-20-02-CN 3300 XL 8 mm Proximity Probe represents the industry standard for non-contacting displacement measurements in high-speed rotating machinery. As a critical component of the Bently Nevada Asset Condition Monitoring ecosystem, this eddy current sensor monitors radial vibration, axial position, and speed on fluid-film bearing machines.

The sensor operates by generating an electromagnetic field that detects the precise distance between the probe tip and the target shaft. This "contactless" architecture ensures zero mechanical wear, providing long-term reliability for steam turbines, centrifugal compressors, and large scale pumps. Its robust design minimizes thermal drift and maintains high-frequency response, allowing engineers to capture subtle shaft malfunctions before they escalate into catastrophic failures.


Technical Configuration

The model string 330104-00-03-20-02-CN follows a specific modular logic defined by Bently Nevada to match precise mechanical requirements:

Unthreaded Length (00)

This option specifies 0 mm of unthreaded length. The entire case features threads, allowing for maximum flexibility when adjusting the probe depth within a mounting bracket or housing.

Overall Case Length (03)

The probe features a total case length of 30 mm. This compact form factor suits tight installation spaces where clearance between the machine casing and the shaft is limited.

Total Length (20)

The probe includes an integrated cable with a total length of 2.0 meters (6.6 feet). This length must match the Proximitor® sensor calibration to ensure signal integrity and accurate linear output.

Connector and Cable-Type (02)

This configuration utilizes the Miniature coaxial ClickLocTM connector and standard cable. The ClickLoc™ mechanism prevents accidental disconnection due to machine vibration and requires no special tools for secure attachment.

Agency Approvals (CN)

The CN suffix designates country-specific approvals for the Chinese market. It ensures compliance with local safety standards and hazardous area certifications required for industrial deployment in China.

Installation Guide

Correct installation determines the accuracy of the entire Turbine Supervisory Instrumentation (TSI) system. Engineers must prioritize the following steps:

Gap Voltage Calibration

Before tightening the probe, the technician must set the "Gap." Connect the probe to the Proximitor® and adjust the distance until the DC output voltage reads approximately -10.0 VDC. This places the probe in the center of its linear range.

Cable Management

Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the coaxial cable. Sharp kinks damage the internal shielding, leading to signal "noise" or false vibration trips.

Environmental Sealing

Always use a terminal box or condulet to protect the ClickLoc™ connectors from oil, moisture, and debris. While the probe tip is resilient, the connector interface remains the most vulnerable point for signal degradation.


Engineering Advantages

Harsh Environment Resilience

The 330104-00-03-20-02-CN thrives in the presence of synthetic lubricants and high temperatures. The Ryton® probe tip and stainless steel body resist chemical corrosion, ensuring the sensor lasts as long as the machine it monitors.

Seamless TSI Integration

This probe integrates directly with 3500 Series Monitoring Systems. It provides the high-fidelity data required for advanced diagnostics, including Orbit Plots and Bode Plots, which are essential for identifying shaft cracks or bearing misalignments.

ClickLoc™ Reliability

The gold-plated ClickLoc™ connectors solve the "loose connection" issues prevalent in older 7200 series models. This locking mechanism guarantees a constant electrical impedance, which is vital for maintaining the 200 mV/mil scale factor.


Technical FAQs

Q1: Can I use this 2.0-meter probe with a 5.0-meter Proximitor?

A1: No. The total system length (Probe + Extension Cable) must match the Proximitor’s calibration (typically 5m or 9m). Using a 2.0m probe in a 5.0m system without the correct extension cable will result in massive calibration errors.

Q2: What is the specific benefit of the "CN" approval suffix?

A2: The CN suffix indicates the hardware meets specific Chinese regulatory standards for explosion-proof and intrinsic safety. It is functionally identical to standard 3300 XL probes but includes the necessary documentation for legal operation within China.

Q3: How do I know if the probe tip is damaged?

A3: Inspect the Ryton® tip for cracks or heavy scoring. Electrically, you can check the resistance; a standard 3300 XL 8mm probe should show a resistance between 4.0Ω and 8.0Ω between the center conductor and the outer shield.

Q4: Is the 3300 XL 8mm probe compatible with older 3300 series monitors?

A4: Yes, the 3300 XL series is backward compatible. It provides improved performance and better temperature stability while maintaining the same electrical characteristics as the legacy 3300 series.
