Bently Nevada 330104-00-07-50-02-00 8mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-07-50-02-00 is a precision-engineered 8mm proximity probe from the industry-standard 3300 XL series. This eddy current sensor is designed for non-contacting vibration and position monitoring of rotating machinery shafts. Featuring a 70mm case length and a 5.0-meter total system length, it provides reliable, high-resolution data for Machinery Protection Systems (MPS) in power generation, oil and gas, and general industrial applications.

Installation & Maintenance

1. Thread Engagement: The 330104-00-07-50-02-00 features an M10x1 thread. During installation, ensure the probe is securely tightened into the machine casing to prevent mechanical resonance that could interfere with vibration signals.

2. Gap Calibration: Using a digital voltmeter and a 3300 XL Proximitor, set the probe gap to the center of the linear range (typically -10.0 Vdc). This ensures the sensor can accurately capture both positive and negative shaft displacements.

3. ClickLoc Connection: The miniature coaxial ClickLoc connector is designed for secure, low-impedance signal transfer. Ensure the connector is clean and fully engaged to maintain the 0.7 ms dynamic response and IP67 protection rating.

Engineering Advantages

The 3300 XL series is recognized globally for its linearity and temperature stability. The 330104-00-07-50-02-00 offers a robust solution for medium-sized machinery. With its IP67 rating, it resists ingress from dust and moisture, while the 100 MΩ insulation resistance ensures high signal-to-noise ratios even in electrically active environments. This configuration is optimized for standard industrial monitoring where hazardous area certification is not a requirement.

Technical FAQs

Q1: What is the benefit of the ClickLoc connector?
A1: ClickLoc connectors provide a secure, vibration-resistant connection that is easier to install and more reliable than traditional threaded coaxial connectors.

Q2: Can this probe be used for axial thrust measurements?
A2: Yes, the 3300 XL 8mm probe is suitable for both radial vibration and axial position (thrust) monitoring.

Q3: Is a 5.0m system length interchangeable with a 9.0m system?
A3: No. This probe is specifically designed for a 5.0-meter system. It must be paired with a 3300 XL Proximitor and extension cable that together equal a 5.0-meter total electrical length for accurate calibration.
