Bently Nevada 330709-000-100-10-02-00 — Product Description, Technical Specifications and Related Models

1. Product Overview

The Bently Nevada 330709-000-100-10-02-00 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 uses eddy-current sensing technology to measure changes in the gap between its sensing tip and an electrically conductive metal target, such as a rotating shaft. When connected to a compatible Proximitor Sensor and machinery monitoring system, it provides an electrical signal that can be used to assess shaft movement and changes in machine operating conditions.

This type of probe is commonly used in industrial facilities where rotating equipment must be monitored continuously. Typical applications include turbines, compressors, pumps, generators, and other machinery in which shaft position and vibration measurements contribute to equipment condition assessment.

The model has an M16 × 1.5 mounting thread, 100 mm case length, 1.0 m total length option, unarmored construction, and a miniature coaxial ClickLoc connector. These characteristics define its mechanical installation and connection arrangement.

The probe is one component of a complete measurement system. Its performance depends on the correct probe gap, target material, cable configuration, compatible Proximitor Sensor, and monitoring equipment.

2. Technical Parameters

Important technical distinction: The 100 mm dimension refers to the probe case length. The 1.0 m option refers to the total probe/cable length configuration. These are separate dimensions and should not be used interchangeably in engineering drawings or purchasing specifications.

The stated linear range and scale factor are characteristics of the compatible 3300 XL 11 mm transducer system. Actual performance depends on the complete system configuration and specified target conditions.

Weight information: An exact component weight and shipping weight have not been established for this particular ordering code. For accurate logistics, inventory records, or formal technical documentation, obtain the weight of the supplied unit rather than relying on an unverified estimate.

3. Model Number Breakdown

The ordering code identifies the probe model, unthreaded length, case length, total length, connector configuration, and approval option.

The 100 segment identifies the 100 mm case-length configuration. This is important when checking the physical clearance available around the machine and determining whether the probe can be mounted at the required measurement point.

The 10 segment identifies the 1.0 m total length option. Cable routing and the distance to the associated Proximitor Sensor should be checked against the intended system arrangement.

The 02 segment identifies the connector and standard cable configuration. When replacing an existing probe, ensure that the connector, cable arrangement, and companion electronics are compatible.

The 00 approval option should not be interpreted as evidence of hazardous-area certification. Where a site requires specific approvals, confirm the required configuration before ordering.

4. Product Introduction and Operating Principle

The 330709-000-100-10-02-00 is designed to measure the relative distance between a stationary probe and a conductive target, commonly a rotating shaft.

An electromagnetic field is generated at the probe tip. When the target moves closer to or farther away from the tip, the electrical characteristics of the sensing circuit change. The compatible Proximitor Sensor converts these changes into an electrical output that can be interpreted by the machinery monitoring system.

Because the probe does not need to touch the shaft, it can measure shaft movement while the machine is operating. This makes it suitable for applications where direct contact would be impractical or where continuous measurement is required.

The probe’s 11 mm sensing family provides a longer linear measurement range than the standard 8 mm system under the specified operating conditions. This can be useful for applications that require a greater measurement range, such as selected shaft-position or turbine monitoring installations.

The probe itself does not independently identify every mechanical fault. Instead, it provides measurement data that can be analyzed alongside machine speed, load, operating history, bearing condition, and other monitoring information.

Correct installation is essential. The mounting position, probe gap, target geometry, cable routing, connector condition, and compatibility of the associated electronics all affect the reliability of the measurement.

5. Product Applications

5.1 Steam Turbines

Steam turbines operate under changing thermal and mechanical loads. Shaft position and vibration measurements can help engineers assess rotor movement and monitor changes in machine behavior.

A compatible proximity probe can be installed near a designated shaft or bearing measurement point. The resulting data can contribute to shaft-motion monitoring and support investigations into abnormal operating trends.

The 100 mm case length must be considered during installation to ensure that the probe fits the mounting arrangement and can be positioned at the required measurement gap.

5.2 Gas Turbines

Gas turbines operate at high rotational speeds and may experience substantial temperature and load variations. Monitoring shaft movement can provide useful information about machine stability and changing operating conditions.

The probe may be considered where the measurement system, installation location, and environmental requirements are appropriate. Temperature exposure and mounting conditions must be evaluated before use.

5.3 Industrial Compressors

Industrial compressors are often used in continuous-process operations, where unexpected equipment shutdowns can affect production and maintenance costs.

A compatible proximity probe can supply shaft-motion measurements that help maintenance teams identify changes from established operating patterns. Such changes may justify further investigation into imbalance, misalignment, bearing deterioration, or other mechanical conditions.

The probe provides measurement data rather than a definitive fault diagnosis. Engineers must interpret the signal in the context of the machine’s operating conditions and other available measurements.

5.4 Pumps and Pump Assemblies

Industrial pumps may develop changes in shaft movement as bearings wear, alignment changes, or operating conditions vary.

When installed in a suitable proximity monitoring system, the probe can contribute shaft-displacement data for condition assessment. Correct selection of the measurement point is important because the probe measures the gap to a conductive target rather than general machine-casing vibration.

5.5 Generators and Rotating Electrical Machinery

Large generators and other rotating electrical machines may require continuous shaft-motion monitoring. A properly configured proximity system can provide measurements used to evaluate rotor movement and investigate changes during normal operation or changing loads.

The probe’s suitability depends on shaft geometry, required measurement range, available mounting space, environmental conditions, and compatibility with the existing monitoring equipment.

5.6 Expanders and Other Rotating Equipment

The probe may also be suitable for selected expanders, gear-driven assemblies, and other industrial rotating machines that require non-contact shaft measurement.

Before installation, engineers should confirm that the target material, mounting dimensions, case length, cable routing, and complete transducer system are appropriate for the application.

6. Product Advantages

6.1 Non-Contact Measurement

The probe measures the distance to a conductive target without physical contact. This makes it suitable for monitoring shaft movement in machinery operating at high speeds or for extended periods.

Because the sensing tip does not touch the rotating shaft, the measurement method avoids the friction and contact wear associated with a contacting sensor.

6.2 Continuous Monitoring Capability

When connected to a compatible Proximitor Sensor and monitoring system, the probe can provide ongoing shaft-motion data.

Continuous measurements allow maintenance teams to compare current machine behavior with established trends and investigate unusual changes. This can support condition-based maintenance and help prioritize inspections.

6.3 Defined Mechanical Configuration

The M16 × 1.5 mounting thread and 100 mm case length provide clearly identified mechanical dimensions for installation planning.

These dimensions are particularly important when replacing a probe in an existing machine. The case length must fit the available mounting space, while the threaded section and probe position must allow the required sensing gap to be established.

6.4 Durable Construction

The AISI 304 stainless-steel case provides mechanical strength and resistance to corrosion in many industrial environments. The PPS sensing tip and FEP-insulated cable are part of the probe’s construction.

Actual suitability still depends on the environment, including temperature, moisture, chemical exposure, vibration, and mechanical protection requirements.

6.5 Defined Cable and Connector Arrangement

The 1.0 m total length option and miniature coaxial ClickLoc connector identify important parts of the electrical configuration.

Matching these details to the existing system can reduce installation problems caused by incompatible connectors, unsuitable cable lengths, or an incorrectly configured measurement chain.

6.6 Support for Machinery Condition Assessment

The probe provides measurement data that can be used in a broader machinery condition-monitoring program.

When combined with operating history, other sensor measurements, and engineering analysis, the data can help maintenance personnel identify changes in shaft behavior and plan inspections more effectively.

6.7 Suitable for Dedicated Measurement Points

The threaded mounting arrangement supports installation at a designated measurement point when the machine design provides a suitable mounting provision.

This can help maintain consistent probe positioning, which is important when comparing measurements over time.

7. Brand and Product Series

The 3300 XL 11 mm family is intended for industrial applications that require non-contact proximity measurements. Different models within this family may use different case lengths, threads, cable lengths, armor configurations, and connector options.

The family designation alone does not establish interchangeability. The complete ordering code and the requirements of the installed transducer system should be checked before a replacement is selected.

8. Five Related Models in the Same Series

The following models are comparison candidates from the 3300 XL 11 mm family or a closely related configuration. They are useful for comparing case lengths and construction, but they should not be regarded as automatic replacements for the target model.

Related Model Comparison

330709-000-060-10-02-00 has a shorter case length and may be considered where the mounting arrangement requires less physical length. The available mounting depth and required probe gap must be checked.

330709-000-080-10-02-00 and 330709-000-090-10-02-00 provide shorter case configurations within the same general probe family. They may be useful when comparing alternative installation arrangements.

330709-000-100-10-02-00 is the target configuration, with a 100 mm case length and 1.0 m total length option.

330710-000-100-10-02-00 represents the corresponding armored probe family. Armor can provide additional mechanical protection in suitable installations, but the actual cable and connector arrangement should be confirmed before ordering.

The models listed above are intended as comparison candidates. Confirm the complete ordering code, availability, dimensions, and compatibility before purchasing. The weight values are marked as unconfirmed where an exact figure is not established.

9. Five Related Models from the Same Brand

The following products cover common proximity-measurement and machinery-monitoring functions. Some are complementary components rather than direct substitutes for the target probe.

9.1 3300 XL Proximitor Sensor

The Proximitor Sensor is a key component in the proximity measurement chain. It processes the electrical characteristics of a compatible probe and provides a measurement output for the monitoring system.

When selecting a Proximitor Sensor, check the probe family, cable arrangement, required system length, and monitor input requirements together.

9.2 3300 XL Extension Cable

The extension cable connects the probe to the compatible Proximitor Sensor. Its length and electrical characteristics are important parts of the complete transducer configuration.

A cable should not be selected solely because its connector appears to fit. The probe, cable, and sensor must be compatible as a complete measurement chain.

9.3 3300 XL 8 mm Proximity Probe

The 8 mm proximity probe family also uses non-contact sensing, but it has different probe geometry and sensing characteristics from the 11 mm family.

It may be suitable for installations designed around the 8 mm system. It should not automatically replace an 11 mm probe without checking the sensing system, target geometry, calibration, and required measurement performance.

9.4 3500/42M Monitoring Module

This module belongs to a rack-based machinery monitoring system. Depending on its configuration, it supports vibration and position monitoring using compatible system inputs.

It serves a different role from the proximity probe: the probe senses the target, while the monitoring module handles measurements within the configured monitoring system.

9.5 3500/22M Data Interface

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

The dimensions and weights of these related products depend on the exact hardware version, cable length, and accessories. Verify those details before using them in engineering drawings, purchasing specifications, or shipping calculations.

10. Dimensions and Weight Summary

The 100 mm case length is the key physical dimension when assessing whether the probe fits the intended mounting point. It does not describe the entire probe and cable assembly.

The 1.0 m total length option identifies the cable-length configuration. The actual distance between the probe and the Proximitor Sensor should be checked against the system requirements and cable-routing arrangement.

For weight-sensitive applications, avoid substituting an estimated figure for a verified specification. The supplied unit should be weighed or its exact technical documentation checked if the weight is needed for logistics, inventory management, or engineering calculations.

11. Installation and Maintenance Recommendations

11.1 Verify Mechanical Compatibility

Confirm the M16 × 1.5 thread, 100 mm case length, available mounting depth, and required probe position before installation.

The probe must be mounted securely without interfering with the rotating shaft or nearby components.

11.2 Set the Probe Gap Correctly

Set the probe gap according to the instructions for the complete transducer system. An unsuitable gap can affect the measurement signal and may prevent the system from operating within its intended linear range.

11.3 Check the Cable and Connector

Verify that the 1.0 m probe configuration, standard cable, miniature coaxial ClickLoc connector, and Proximitor Sensor form a compatible arrangement.

Inspect the cable and connector for damage. Avoid sharp bends, excessive pulling force, abrasion, and exposure to conditions outside the cable’s intended operating limits.

11.4 Confirm Target Suitability

The probe is designed for a conductive metal target. Target material, diameter, surface condition, and installation geometry can affect measurement performance.

Use the target specifications and installation conditions appropriate to the intended transducer system.

11.5 Evaluate Environmental Conditions

Consider operating temperature, moisture, chemical exposure, vibration, and the need for mechanical protection.

The approval option in the model number should also be checked against site requirements. Do not assume that the 00 option satisfies a hazardous-area certification requirement.

11.6 Perform Commissioning Checks

After installation, verify the probe gap, signal behavior, connector integrity, and monitoring-system configuration according to the applicable instructions.

Establish a baseline under known operating conditions so that subsequent changes can be compared meaningfully.

11.7 Maintain Configuration Records

Record the full probe model, installation location, cable arrangement, associated Proximitor Sensor, and relevant monitoring settings.

Maintaining accurate records helps reduce replacement errors and makes it easier to identify configuration differences during future maintenance.
