Bently Nevada 330104-12-20-10-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime threatens production targets, the Bently Nevada 330104-12-20-10-02-00 provides reliable shaft vibration and position monitoring. This 3300 XL 8 mm proximity probe is designed for harsh industrial environments, offering precise measurements to protect critical rotating machinery. As part of the trusted 3300 XL series, it integrates seamlessly with Bently Nevada monitoring systems for continuous asset protection.

Technical Specifications Breakdown

The 330104-12-20-10-02-00 features an M10 x 1 threaded probe with armor, ensuring robust mechanical integrity. Key specifications include:

Unthreaded Length: 12 mm

Overall Case Length: 200 mm

Total Length: 1.0 meter (3.3 feet)

Connector: Miniature coaxial ClickLoc connector with standard cable

Probe Tip Material: Polyphenylene sulfide (PPS)

Probe Case Material: AISI 303 or 304 stainless steel (SST)

Nominal Probe DC Resistance: 7.59 ± 0.50 Ω (for 1.0 m length)

These parameters ensure accurate gap voltage and linear output for vibration analysis.

Industry Applications

Engineers rely on the 330104-12-20-10-02-00 for monitoring turbines, compressors, pumps, and fans. Its 8 mm tip diameter suits tight mounting spaces, while the PPS tip withstands high temperatures. The stainless steel case resists corrosion in chemical or offshore environments. By using this probe, maintenance teams detect early bearing wear or imbalance, reducing costly repairs.

Installation & Setup Guidance

Mount the probe with the M10 x 1 thread into a pre-drilled hole, ensuring proper clearance to the target. Use the ClickLoc connector for secure cable attachment. Gap the probe at 1.27 mm (50 mils) to an AISI 4140 steel target for optimal linear range. Verify the system operates with a -24 Vdc power supply and 10 kΩ load. Always follow Bently Nevada installation drawing 140979 for nonincendive circuits.

Maintenance & Reliability

Periodically inspect the probe tip for contamination or damage. The Viton O-ring seal maintains differential pressure integrity. Check cable connections for wear. With proper care, the 330104-12-20-10-02-00 delivers years of reliable service, minimizing lifecycle costs.

Compatible Systems

This probe works with all 3300 XL 8 mm Proximitor sensors and extension cables. It is compatible with Bently Nevada monitoring racks and software for real-time data acquisition. Ensure the system uses only 3300 XL 8 mm components for specified accuracy.

Buying Guide & Purchasing Advice

Before ordering, verify the total length (1.0 meter) and connector type (ClickLoc) meet your installation requirements. The 330104-12-20-10-02-00 does not require agency approvals (option 00).
