Bently Nevada 330709-000-080-10-02-00 — Industrial Product Description and Technical Specifications

1. Product Overview

The Bently Nevada 330709-000-080-10-02-00 is a 3300 XL 11 mm proximity probe designed for non-contact measurement of shaft displacement and vibration-related movement in industrial rotating machinery.

The probe operates using eddy-current sensing technology. When installed near a conductive metal target, such as a rotating shaft, it detects changes in the gap between the probe tip and the target surface. A compatible Proximitor Sensor converts these changes into an electrical signal that can be used by a machinery monitoring system.

This type of sensor is commonly used where continuous information about shaft movement is important to equipment reliability. Typical installations include turbines, compressors, pumps, generators, and other rotating machines operating under demanding industrial conditions.

The model’s main identifying features are its M16 × 1.5 mounting thread, 80 mm case length, 1.0 m total length configuration, unarmored construction, and miniature coaxial ClickLoc connector. These configuration details should be checked carefully when selecting a replacement, as a probe with a similar appearance may have different dimensions or electrical requirements.

2. Technical Parameters

The table below summarizes the principal specifications of the target model. Dimensions refer to the stated probe configuration; the weight is a practical reference value and should be verified against the actual supplied unit if exact logistics or engineering data is required.

Technical clarification: The measurement range and sensitivity above describe the compatible 3300 XL 11 mm transducer system, not a guarantee that the probe will operate correctly with arbitrary electronics. The complete probe, cable, sensor, and monitor configuration must be compatible.

Temperature consideration: The stated temperature range should not be interpreted as an unconditional guarantee for every installation. Seal performance, mounting conditions, cable exposure, and environmental conditions must be assessed, particularly for low-temperature applications.

3. Model Number Breakdown

The complete part number identifies the mechanical and electrical configuration of the probe.

The 080 field is particularly important because it identifies the 80 mm case-length configuration. It should not be confused with the total probe and cable length, which is specified separately by the 10 field.

The 02 connector option also matters during replacement. Even if a different probe has the same thread and case length, its connector and cable arrangement must match the intended installation.

4. Product Introduction and Operating Principle

The 330709-000-080-10-02-00 is intended to measure the relative distance between a stationary probe and a conductive target, usually a rotating shaft. It uses an electromagnetic field at the probe tip to detect changes in this distance.

When the shaft moves closer to or farther away from the probe, the electrical characteristics of the sensing circuit change. The compatible Proximitor Sensor converts the change into an electrical output that can be interpreted by the machinery monitoring system.

This measurement method is useful for rotating machinery because the probe can detect shaft movement without touching the shaft. It avoids the direct contact and friction that would otherwise be unsuitable for measuring a high-speed rotating component.

The probe itself is only one component of the measurement chain. Reliable results depend on correct installation, suitable target geometry, appropriate probe gap, compatible electronics, and correct monitoring-system configuration.

5. Product Applications

5.1 Steam Turbines and Gas Turbines

Turbines operate at high speeds and under changing thermal and mechanical loads. Shaft vibration and displacement measurements can help maintenance personnel understand changes in rotor behavior, bearing performance, and overall machine stability.

A compatible proximity probe can be installed at an appropriate measurement point to provide shaft-motion information to the monitoring system. The exact measurement arrangement depends on the turbine design and the requirements of the monitoring installation.

5.2 Industrial Compressors

Compressors used in process plants often operate continuously and may be expensive to stop unexpectedly. Shaft-displacement measurements can help engineers monitor operating trends and investigate unusual vibration patterns.

Potential causes of changing shaft behavior include imbalance, misalignment, bearing deterioration, and changes in operating conditions. The probe provides measurement data; identifying the root cause requires analysis of the complete monitoring data and machine operating history.

5.3 Pumps and Pump Assemblies

Industrial pumps can develop changes in shaft motion as bearings wear, alignment changes, or operating conditions vary. When a compatible proximity monitoring system is installed, the probe can contribute useful information for condition assessment.

It is important to select the measurement point carefully. A proximity probe measures the gap between its tip and a conductive target; it is not interchangeable with a sensor designed specifically for measuring the vibration of a machine casing.

5.4 Generators and Electric Motor Systems

Large rotating electrical machines may require monitoring of shaft movement and vibration to help maintain stable operation. A properly configured proximity system can provide continuous measurements that support trend analysis and maintenance planning.

The suitability of this particular probe depends on the required sensing range, mounting dimensions, shaft geometry, and compatibility with the existing monitoring system.

5.5 Expanders and Other Rotating Equipment

The probe may also be considered for selected expanders, gear-driven machinery, and other industrial rotating equipment. Before installation, engineers should verify the operating environment, conductive target material, available mounting space, cable routing, and required measurement characteristics.

6. Product Advantages

6.1 Non-Contact Measurement

The probe measures the gap to a conductive target without touching it. This makes it suitable for monitoring shaft movement in equipment that operates continuously or at high rotational speeds.

6.2 Suitable for Continuous Monitoring

When connected to a compatible Proximitor Sensor and monitoring system, the probe can provide ongoing measurement data. Trends in this data can help maintenance teams recognize changes from normal operating behavior and determine when further inspection may be needed.

6.3 Defined Mechanical Configuration

The M16 × 1.5 thread and 80 mm case length provide clear dimensional information for installation planning. A defined mounting configuration is helpful when selecting a replacement for an existing machine installation.

6.4 Durable Construction

The stainless-steel case provides mechanical strength and resistance to corrosion in many industrial environments. The PPS probe tip and FEP-insulated cable are components of the probe’s construction and are intended for the specified operating conditions.

6.5 Compact Sensor Arrangement

The probe is designed for installation close to the measurement target. This can be useful in machinery where space around the shaft, bearing housing, or mounting bracket is limited.

6.6 Clear Cable and Connector Specification

The 1.0 m length option and miniature coaxial ClickLoc connector identify important parts of the electrical connection arrangement. Confirming these details helps avoid replacement problems caused by mismatched cable lengths or connectors.

6.7 Supports Predictive Maintenance

The probe can contribute to a condition-monitoring strategy by supplying shaft-motion data. Combined with operating history, other measurements, and appropriate engineering analysis, this information can help maintenance personnel plan inspections and reduce unnecessary interventions.

The probe does not independently diagnose every mechanical fault. Its value comes from providing reliable measurements within a correctly configured monitoring system.

7. Brand and Product Series

The 3300 XL 11 mm family is intended for applications where its sensing range and installation arrangement are suitable. A different probe family may have a different tip size, linear range, mounting arrangement, or electrical configuration, so selection should be based on the complete system requirements rather than the series name alone.

8. Five Related Models in the Same Series

The following models are useful comparison candidates. They share the 3300 XL 11 mm family or a closely related probe configuration, but the differences in mechanical dimensions and cable construction must be considered before choosing a replacement.

The first four models differ mainly in the case-length field. They may be relevant where the installation requires a different mounting length, but they should not be substituted without checking the available space, thread engagement, probe gap, and target position.

The fifth model uses the corresponding M16 × 1.5 threaded probe family with armor. Armor can provide additional mechanical protection in suitable installations, but the physical dimensions and cable routing differ from an unarmored configuration.

Selection reminder: The related models above are comparison candidates, not a declaration of universal interchangeability. Verify that each complete part number is available in the required configuration before ordering.

9. Five Popular Related Models from the Same Brand

The following models cover common components and equipment families used in industrial machinery monitoring. They perform different roles, so they should be selected according to the requirements of the complete installation.

9.1 3300 XL Proximitor Sensor

The Proximitor Sensor is an important part of the measurement chain. It processes the electrical behavior of a compatible probe and provides a usable output to the monitoring system.

When selecting a sensor, the probe family, cable arrangement, required system length, and monitor input requirements should all be checked.

9.2 3300 XL Extension Cable

The extension cable connects the probe to the compatible Proximitor Sensor. Its electrical characteristics and length form part of the complete transducer system, so a cable should not be chosen solely because its connectors appear to fit.

9.3 3300 XL 8 mm Proximity Probe

The 8 mm family also uses proximity sensing, but it has a different probe-tip configuration and sensing geometry. It can be appropriate for installations designed around that family, but it should not automatically replace an 11 mm probe.

9.4 3500/42M Monitoring Module

This module belongs to a rack-based machinery monitoring system and can support vibration and position monitoring, depending on its configuration. It operates at the monitoring-system level rather than functioning as a standalone proximity probe.

9.5 3500/22M Data Interface

The data interface supports communication and data handling within a compatible monitoring system. It complements monitoring hardware but does not replace the probe, extension cable, or Proximitor Sensor required for proximity measurements.

The dimensions and weights of the related products are intentionally marked as unconfirmed where a reliable exact figure is not available. Module revisions, connector arrangements, and accessory configurations can affect the final dimensions and shipping weight.

10. Installation and Maintenance Considerations

Correct installation is essential to measurement reliability. A probe that is mechanically secure but installed at an unsuitable gap may not deliver the expected measurement behavior. Likewise, an incorrect cable or incompatible sensor can affect the performance of the complete transducer system.

For routine maintenance, inspect the cable and connector for visible damage, check the mounting arrangement, and compare operating measurements with established baseline trends. Any change in signal behavior should be assessed in the context of machine speed, load, temperature, and other relevant measurements.

11. Dimensions and Weight Summary

The 80 mm case length and 1.0 m total length option describe different aspects of the product. The former refers to the case configuration, while the latter identifies the total probe/cable length option.

The estimated component weight is provided for preliminary planning only. It should not be treated as a certified product weight or a shipping-weight specification. For purchasing records, freight calculations, or engineering documentation, confirm the actual weight of the supplied configuration.

12. Overall Product Assessment

The Bently Nevada 330709-000-080-10-02-00 is a 3300 XL 11 mm proximity probe with an M16 × 1.5 mounting thread, an 80 mm case length, a 1.0 m total length option, and a miniature coaxial ClickLoc connector.

Its principal role is to provide non-contact shaft-displacement measurements for compatible industrial machinery monitoring systems. It can contribute useful information about shaft movement and vibration behavior when correctly installed and paired with compatible electronics.

The main selection priorities are mechanical fit, case length, cable length, connector configuration, target geometry, and compatibility with the complete transducer system. Approval requirements and environmental conditions should also be reviewed before installation.

For a replacement purchase, the safest approach is to compare the full ordering code against the installed unit and verify the dimensions, electrical compatibility, and approval requirements. Exact product and shipping weights should be confirmed independently when those figures are required for formal documentation.
