Product Overview

When unplanned downtime strikes rotating machinery, the Bently Nevada 330171-01-10-10-02-00 3300 5mm Probe delivers the precise vibration data you need to act fast. This eddy-current probe, part of the trusted 3300 series, converts mechanical displacement into an electrical signal for continuous monitoring. Manufactured in the U.S.A., it features a 1/4-28 UNF thread and a polyphenylene sulfide (PPS) probe tip, ensuring reliable performance in demanding industrial environments.

With a total length of 1.0 meter (3.3 feet) and a miniature coaxial ClickLoc connector, this probe integrates seamlessly into existing Bently Nevada monitoring systems. Its AISI 304 stainless steel case provides corrosion resistance, while the 0.323 kg weight makes handling and installation straightforward. Whether you are protecting turbines, compressors, or pumps, the 330171-01-10-10-02-00 offers the accuracy and durability your operation demands.

Technical Specifications

Understanding the key parameters of the 330171-01-10-10-02-00 helps you make an informed purchasing decision. Here are the critical specifications:

Product Type: 330171 3300 5mm Probe, 1/4-28 UNF thread, without armor

Unthreaded Length Option: 0.1 in (01)

Overall Case Length Option: 1.0 in (10)

Total Length Option: 1.0 meter (3.3 feet)

Connector Option: Miniature coaxial ClickLoc connector, standard cable

Probe Tip Material: Polyphenylene sulfide (PPS)

Probe Case Material: AISI 304 stainless steel (SST)

Weight: 0.323 kg

These specifications directly impact your maintenance budget. The PPS tip resists wear, reducing replacement frequency. The stainless steel case withstands harsh conditions, minimizing corrosion-related failures. The 1.0-meter cable length suits many installations without extra extension costs.

Industry Applications

The 330171-01-10-10-02-00 excels in critical rotating equipment across industries. In power generation, it monitors turbine shaft vibration, helping operators detect imbalance or misalignment early. In oil and gas, it safeguards compressors and pumps, preventing catastrophic failures that halt production.

For example, a petrochemical plant using this probe on a high-speed compressor can continuously track shaft displacement. The data feeds into a protection system, triggering alarms before damage occurs. This proactive approach reduces unplanned downtime, which often costs thousands of dollars per hour. By investing in a reliable probe, you avoid the far higher expense of emergency repairs and lost output.

Installation & Setup Guidance

Proper installation ensures accurate readings and long service life. Follow these best practices for the 330171-01-10-10-02-00:

Drill and tap a mounting hole for the 1/4-28 thread. Use a #3 or larger tap drill for optimal thread engagement.

Respect the maximum thread engagement of 0.375 inches to avoid damaging the probe case.

Apply the recommended probe case torque of 5.1 N·m (45 in·lb), with a maximum of 7.3 N·m (65 in·lb).

Maintain a minimum cable bend radius of 25.4 mm (1.0 in) to prevent cable stress.

Connect using the miniature coaxial ClickLoc connector, ensuring a secure fit.

Correct installation minimizes measurement errors and prevents mechanical damage. Taking time to set the gap properly—typically around 1.27 mm (50 mils) for optimal linear range—reduces the need for rework and calibration, saving labor costs.

Maintenance & Reliability

Routine inspection of the probe and its cable is essential for consistent performance. Check for physical damage, such as cuts or kinks in the cable, and verify that the connector remains tight. Clean the probe tip gently with a soft cloth to remove debris, but avoid abrasive materials that could scratch the PPS surface.

The probe operates reliably across a wide temperature range, from -35°C to +177°C (-31°F to +351°F). However, exposing it to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. In cold environments, consider additional insulation or heating to protect the probe.

By following a simple preventive maintenance schedule—quarterly visual checks and annual functional tests—you extend the probe's lifespan. This reduces replacement costs and avoids unplanned outages. The 330171-01-10-10-02-00's robust construction already minimizes failures, but regular care maximizes your return on investment.

Compatibility & Integration

The 330171-01-10-10-02-00 is designed to work with Bently Nevada 3300 series monitoring systems. Its miniature coaxial ClickLoc connector mates with standard extension cables, allowing flexible routing to proximity sensors or monitors. The probe's 1.0-meter cable length suits most installations, and you can choose from optional cable lengths (0.5, 1, 2, 5, or 9 meters) if a different reach is needed.

This probe operates with a -17.5 Vdc to -26 Vdc power supply, drawing a maximum of 12 mA. It outputs a signal proportional to shaft displacement, which the monitoring system interprets for display and alarm. For best performance, use it with a compatible Bently Nevada proximitor sensor and extension cable, ensuring a matched system that delivers accurate data.

Selection Guide & Purchasing Advice

Before ordering the 330171-01-10-10-02-00, verify your system's requirements. Check the thread size (1/4-28 UNF), total length (1.0 meter), and connector type (miniature coaxial ClickLoc). Confirm that your monitoring system accepts this probe's signal format. If you are replacing an existing probe, match the part number exactly to ensure compatibility.
