Bently Nevada 330709-000-080-10-02-00 3300 XL 11 mm Proximity Probe

Product Introduction

The Bently Nevada 330709-000-080-10-02-00 is a 3300 XL 11 mm proximity probe designed for accurate measurement of radial vibration and axial position in rotating machinery. This model features an M16 x 1.5 thread, an overall case length of 80 mm, and a total length of 1.0 meter (3.3 feet). It is equipped with a miniature coaxial ClickLoc connector and standard cable, without armor. Manufactured in the U.S.A., this probe is part of the trusted 3300 XL series, known for its reliability and performance in industrial condition monitoring.

• Probe Case Thread: M16 x 1.5, max engagement 24 mm
• Probe Case Torque: 63.3 N•m (560 in•lb) for M16x1.5
• Connector-to-connector torque: Finger tight (max 0.565 N•m / 5 in•lb)
• Minimum Bend Radius: 25.4 mm (1.0 in)
• Operating and Storage Temperature: -52°C to +177°C (-62°F to +351°F)

Parameter Analysis

The 330709-000-080-10-02-00 is configured with specific options: unthreaded length 0 mm, overall case length 80 mm, total length 1.0 meter, miniature coaxial ClickLoc connector, and standard cable. These parameters ensure compatibility with standard mounting requirements. The probe’s dc resistance is tightly controlled for consistent signal output. The PPS tip and stainless steel case provide durability in harsh environments. The temperature range allows operation in extreme conditions, though exposure below -34°C may affect the pressure seal.

Application Scenarios

This proximity probe is ideal for monitoring vibration and position in critical rotating machinery such as turbines, compressors, pumps, and other industrial equipment. It is commonly used in conjunction with Bently Nevada 3300/3500 monitoring systems to provide real-time data for predictive maintenance and machine protection.

Installation Guide

Ensure the probe is mounted with the correct thread engagement (max 24 mm) and torque (63.3 N•m for M16x1.5). The connector should be finger tight, with a maximum torque of 0.565 N•m. Maintain a minimum bend radius of 25.4 mm for the cable. For optimal performance, the target surface should be flat with a recommended minimum diameter of 30.5 mm, and the shaft diameter should be at least 152 mm.

Compatibility

This probe is compatible with Bently Nevada 3300 XL series systems and can be used with extension cables and proximity transducers. It is designed to work with standard 3300/3500 monitoring racks. For specific system integration, refer to the service manual provided.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Keep the connector clean and properly torqued. Avoid exposing the probe to temperatures below -34°C to prevent premature failure of the pressure seal. Calibration checks should be performed periodically according to your plant’s maintenance schedule.

Procurement Advice

When ordering the Bently Nevada 330709-000-080-10-02-00, verify that the model number matches your system requirements. Consider purchasing spare probes to minimize downtime. Ensure you source from authorized distributors to guarantee genuine parts and warranty support.
