330172-10-24-05-02-00 | Bently Nevada 5mm Probe with Armor

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330172-10-24-05-02-00 delivers precise, reliable measurement. This 5mm proximity probe, part of the 3300 series, is engineered for permanent installation in rotating machinery monitoring systems. Its armored construction and robust materials ensure long-term performance in demanding industrial environments.

Manufactured in the U.S.A., this probe features a 1/4-28 UNF thread for secure mounting. The 0.5 meter (1.6 feet) total length with a miniature coaxial ClickLoc connector simplifies installation and provides a stable connection. Designed for use with Bently Nevada proximity transducer systems, it offers accurate gap measurements critical for protecting assets.

Technical Specifications

Key parameters for the 330172-10-24-05-02-00 include:

Probe Tip Material: Polyphenylene sulfide (PPS) – offers excellent chemical resistance and dimensional stability.

Probe Case Material: AISI 304 stainless steel (SST) – provides corrosion resistance and mechanical strength.

Thread: 1/4-28 UNF, with a maximum thread engagement of 0.375 inches.

Weight: 0.323 kg – lightweight for ease of handling.

Probe Cable: 75 Ω triaxial, FEP insulated, available in lengths of 0.5, 1, 2, 5, or 9 meters.

Probe Temperature Range: -35°C to +177°C (-31°F to +351°F) – suitable for extreme conditions.

Tensile Strength: 222 N (50 lbf) between probe case and lead, and between lead and extension cable connectors.

Probe Case Torque: 5.1 N·m (45 in·lb) recommended, 7.3 N·m (65 in·lb) maximum.

Connector-to-Connector Torque: Maximum 0.565 N·m (0.42 ft·lbf).

Minimum Cable Bend Radius: 25.4 mm (1.0 in) – prevents cable damage.

These specifications ensure consistent performance when used with compatible Bently Nevada proximity systems, providing accurate vibration and position readings.

Industry Applications

The 330172-10-24-05-02-00 is ideal for vibration monitoring on critical rotating equipment such as turbines, compressors, pumps, and electric motors. Its robust design and wide temperature range make it suitable for harsh environments, including oil and gas, power generation, and heavy manufacturing.

In a typical application, the probe is mounted near a shaft to measure radial vibration or axial position. The 5mm sensing range and high sensitivity allow early detection of mechanical issues, enabling predictive maintenance and reducing unplanned downtime. The armored construction protects against physical damage, ensuring reliable operation even in high-vibration areas.

Installation & Setup Guidance

Proper installation is crucial for accurate readings. Follow these guidelines:

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

Ensure the probe tip is clean and free from debris before installation.

Apply the recommended torque of 5.1 N·m (45 in·lb) to secure the probe case, not exceeding 7.3 N·m (65 in·lb).

Connect the ClickLoc connector securely, applying a maximum torque of 0.565 N·m (0.42 ft·lbf).

Avoid bending the cable beyond the minimum bend radius of 25.4 mm (1.0 in) to prevent damage.

Calibrate the system according to the Bently Nevada manual to ensure proper gap voltage.

Always verify the thread engagement length does not exceed 0.375 inches to prevent interference with internal components.

Maintenance & Reliability

Regular inspection of the probe and cable is recommended. Check for physical damage, loose connections, and signs of wear. The PPS tip and stainless steel case resist corrosion, but periodic cleaning with a soft cloth is advised to maintain accuracy.

Environmental factors such as extreme temperatures or magnetic fields can affect performance. The probe operates reliably between -35°C and +177°C, but exposure below -34°C may risk pressure seal failure. In high magnetic field areas, refer to the effects table to anticipate output variations.

By following a simple maintenance schedule, you can extend the service life of the probe and ensure consistent monitoring, reducing the total cost of ownership.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the following:

Confirm the thread type (1/4-28 UNF) matches your mounting requirements.

Choose the correct cable length (0.5, 1, 2, 5, or 9 meters) for your installation.

Ensure the connector type (miniature coaxial ClickLoc) is compatible with your extension cable.

Check the agency approval option – this model is 'Not Required', but verify your site's regulations.
