Product Overview

The Bently Nevada 330101-00-28-10-02-00 serves as the critical sensory interface for the world-renowned 3300 XL Proximity Transducer System. Engineered for non-contacting measurement of shaft vibration and position, this 8 mm probe delivers unmatched linearity and temperature stability. It excels in high-speed turbomachinery environments, providing vital data to 3500 Monitoring Systems for the protection of steam turbines, gas turbines, and cooling tower fans. By utilizing advanced Ryton® plastic probe tips and high-quality Gold-plated brass connectors, it maintains signal fidelity even in the presence of synthetic lubricants and corrosive process fluids. This specific configuration ensures precise axial or radial measurements, forming the backbone of any robust Machine Protection System (MPS).

Component Architecture & Suffix Breakdown

The alphanumeric string 330101-00-28-10-02-00 defines a specific mechanical and electrical profile tailored for industrial integration.

Unthreaded Length (-00)

Specifies a 0.0-inch unthreaded length, indicating the probe body is fully threaded for maximum mounting flexibility and mechanical stability within the bracket.

Overall Case Length (-28)

Defines a 2.8-inch total case length. This compact form factor allows for installation in tight bearing housings where space is a premium.

Total Length (-10)

Indicates a 1.0-meter (3.3 feet) total cable length. This length is precisely calibrated to match the Proximitor’s internal oscillator frequency for accurate 7.87 V/mm (200 mV/mil) scale factors.

Connector and Cable-Type (-02)

Standardized miniature coaxial cable equipped with a ClickLoc™ connector. This moisture-resistant connector prevents accidental disconnection and maintains low impedance.

Agency Approval (-00)

Configured for standard installations without specific regional hazardous area markings, though the base design inherently meets high industrial safety standards.

Physical & Performance Parameters

Precision Deployment Protocol

Successful deployment requires strict adherence to gap voltage settings. Technicians must set the initial mechanical gap using a digital multimeter connected to the Proximitor's "OUT" and "COM" terminals; a reading of -10.0 Vdc represents the ideal center of the linear range. Avoid bending the coaxial cable with a radius smaller than 25.4 mm (1.0 in) to prevent internal conductor damage. Ensure the probe tip remains free of metallic debris, as any conductive buildup will cause significant measurement error. For high-vibration environments, use Loctite or safety wire to prevent the probe from backing out of the mounting bracket.

Strategic Industrial Benefits

The 3300 XL series offers a 30% improvement in temperature stability compared to previous generations, virtually eliminating "false trips" caused by thermal drift in the bearing housing. Its seamless integration with Honeywell Experion PKS or Emerson DeltaV via 4-20mA or digital Modbus outputs ensures that plant operators receive real-time alerts before a catastrophic bearing failure occurs. The Ryton® tip construction provides chemical resistance to the most aggressive hydraulic fluids, ensuring a service life often exceeding 10 years in continuous operation.

Logistics & Global Shipping

We utilize vacuum-sealed, anti-static industrial packaging to protect the sensitive eddy-current tip and gold connectors. Each shipment includes a factory calibration certificate verifying the linearity across the full 80-mil range.

Critical Troubleshooting FAQ

Q1: Can I trim the cable if it is too long for my junction box?

A1: No. The cable length (1.0 meter) is an integral part of the tuned LC circuit. Cutting or splicing the cable will destroy the calibration and render the vibration data inaccurate.

Q2: What should I check if the gap voltage is stuck at -24V?

A2: A -24V reading usually indicates an "Open Circuit." Check the ClickLoc connector for proper seating or inspect the cable for physical breaks or sharp bends.

Q3: Does this probe require a specific Proximitor?

A3: Yes, it must be paired with a 3300 XL 8 mm Proximitor Sensor. Using a 5 mm or 11 mm Proximitor will lead to incorrect scale factors and non-linear output.
