330101-00-12-10-02-05 | Bently Nevada 8 mm Probe 3/8-24 UNF

Introduction to the 330101-00-12-10-02-05

When machine reliability is non-negotiable, the 330101-00-12-10-02-05 from Bently Nevada delivers the precision you need. This 3300 XL 8 mm probe uses a 3/8-24 UNF thread and comes without armor, making it a straightforward choice for many rotating machinery applications.

Part of the trusted 3300 XL series, this probe is built to withstand harsh conditions. Its robust design helps minimize downtime and maintenance costs, offering long-term value for your operation.

Key Features and Technical Specifications

• Manufacturer: Bently Nevada
• Product Type: 3300 XL 8 mm Probe with 3/8-24 UNF thread
• Unthreaded Length: 0.0 inches
• Overall Case Length: 1.2 inches
• Total Length: 1.0 meter (3.3 feet)
• Connector: Miniature coaxial ClickLoc connector with standard cable
• Approvals: CSA, ATEX, IECEx

The probe features a patented TipLoc molding method for a robust bond between tip and body, and a CableLoc design that provides 330 N (75 lbf) pull strength. This enhances durability and reduces the risk of cable failure, saving you replacement costs.

Performance Metrics That Matter

The 330101-00-12-10-02-05 offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The incremental scale factor is 7.87 V/mm (200 mV/mil) ±5% for standard 1-meter systems, ensuring accurate measurements.

Deviation from best fit straight line is less than ±0.025 mm (±1 mil) over the operating temperature range of 0°C to +45°C (+32°F to +113°F). This precision translates to reliable data, helping you avoid costly false alarms or missed faults.

Installation and Setup

Proper installation is key to maximizing the probe's performance. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). Ensure the probe is mounted securely with the 3/8-24 UNF thread and that the ClickLoc connector is properly engaged.

For field wiring, use 3-conductor shielded triad cable with tinned wiring, sized between 0.2 to 1.5 mm² (16 to 24 AWG). The maximum length between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). Following these guidelines helps maintain signal integrity and reduces installation issues.

Maintenance and Reliability

Regular inspection of the probe and cable is recommended to ensure long-term reliability. The probe's PPS tip and stainless steel case (AISI 303 or 304) resist wear and corrosion. The Viton O-ring helps seal against pressure differentials, but probes are not pressure tested prior to shipment—contact the manufacturer if your application requires testing.

Operating temperature range is -52°C to +177°C (-62°F to +350°F) for standard probes. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. These practices extend service life and reduce total cost of ownership.

Compatibility and Integration

The 330101-00-12-10-02-05 is designed for use with Bently Nevada 3300 XL systems. It works with extension cables and Proximitor sensors to form a complete vibration monitoring solution. The miniature coaxial ClickLoc connector ensures a secure and reliable connection.

With CSA, ATEX, and IECEx approvals, this probe is suitable for hazardous area installations, offering flexibility across various industrial environments.
