330851-02-000-080-50-01-05 Bently Nevada 80mm Probe

Product Overview

The Bently Nevada 330851-02-000-080-50-01-05 is a heavy-duty 25mm proximity probe within the 3300 XL series, specifically engineered for the most demanding industrial environments. This eddy current sensor features a reinforced 80mm armored case capable of withstanding extreme radial compression. Designed for large-scale machinery, it provides a superior linear range for vibration and position monitoring, ensuring high-fidelity data in offshore and high-pressure applications where standard sensors might fail.

Technical Specifications

Installation & Maintenance

1. Torque and Armor: The 330851-02-000-080-50-01-05 supports a high torque capacity of 163N·m. The 4mm SST armor ensures the internal sensing elements remain protected even under significant mechanical stress during installation on heavy casings.

2. Gap Calibration: Calibrate using a 3300 XL 25mm Proximitor. Because of the large 25mm tip, ensure that the target area on the shaft is at least 1.5 times the diameter of the probe tip to avoid side-view interference.

3. Connector Protection: The "01" option includes a pre-installed connector protector. This is vital for maintaining the 100Bar pressure resistance and ensuring signal continuity in submersed or fluid-heavy environments.

Engineering Advantages

This 25mm system is the industry benchmark for monitoring shaft axial displacement and vibration on large steam turbines and generators. The PEEK thermal shield and MIL-STD-810H shock rating allow the 330851-02-000-080-50-01-05 to operate reliably in the presence of extreme thermal cycling and mechanical transients. Its compliance with DNV GL standards makes it a top-tier choice for offshore platforms and maritime propulsion systems where salt-spray resilience (ISO 14993) is mandatory.

Technical FAQs

Q1: What does the "01" connector option provide?
A1: The "01" option includes a miniature coaxial connector with a connector protector, essential for achieving the full IP69K ingress protection rating.

Q2: Can this probe handle extreme cold starts?
A2: Yes, the probe is tested for immediate startup at temperatures as low as -50°C, making it suitable for arctic and high-altitude industrial sites.

Q3: Is a special proximitor required?
A3: Yes, you must pair this with the Bently Nevada 3300 XL 25mm Proximitor Sensor. It is not compatible with standard 8mm Proximitors.
