2. Detailed Product Parameters

The model number 330709-000-060-50-02-05 identifies a 3300 XL 11 mm probe with a 60 mm case-length option, a 5.0 m cable, a standard-cable ClickLoc connector, and a multiple-approval option.

The final suffix 05 is an important difference from the otherwise similar ...-02-00 model: it denotes a multiple-approval configuration. The exact certification markings and suitability for a particular hazardous area should be confirmed for the supplied unit and the installation jurisdiction.

Weight and dimensions: The 60 mm case length and 5.0 m cable length are the identifiable dimensions of this configuration. An exact, verified weight for the complete probe has not been established here, so a numerical weight should not be treated as confirmed. For formal purchasing, shipping, or inventory records, use the actual unit’s technical drawing or packing documentation.

3. Model Number Breakdown

The full ordering code identifies the mechanical design, cable configuration, connector option, and approval option.

The final 05 suffix is particularly important. It identifies an approval option intended for applicable installations requiring multiple agency approvals. The precise markings and certificates must be checked against the product label and the requirements of the installation site.

The 02 connector-and-cable option should also be retained when replacing an existing probe. A FluidLoc cable version is a different configuration and should not be assumed to be identical.

4. Detailed Product Introduction

4.1 Non-contact measurement principle

The 330709 probe uses eddy-current technology to measure the gap between its sensing tip and a suitable conductive target, commonly a rotating shaft.

As the distance between the probe tip and target changes, the electrical response of the sensing system changes. Compatible transducer electronics convert that response into a usable measurement signal.

Because the probe does not need to touch the shaft during normal operation, it is suitable for continuous monitoring installations where contact-based measurement would be impractical.

4.2 3300 XL 11 mm probe design

The 3300 XL 11 mm series is designed for industrial proximity measurement applications requiring the corresponding probe geometry and measurement range.

Depending on the machine design and monitoring arrangement, this family may be used for shaft vibration, axial-position measurement, differential-expansion measurement, and other supported displacement applications.

The correct measurement function depends on the overall system configuration and installation design. A probe should not be selected solely by its physical appearance or series name.

4.3 M16 × 1.5 mounting thread

This model has an M16 × 1.5 mounting thread and an unarmored case. The threaded mounting arrangement allows the probe to be installed in a compatible holder or machine mounting point.

The 60 mm case-length option is important when checking the available installation depth. Before installation, verify the mounting thread, engagement length, probe clearance, and distance from nearby components.

The probe must remain securely mounted during operation and must not contact the rotating target.

4.4 Five-metre cable arrangement

The 5.0 m cable option gives the specified model a defined total cable length for connection to the compatible measurement electronics.

The cable should be routed to avoid sharp edges, abrasion, excessive heat, and mechanical interference. Its minimum bend radius should be observed, and the connector should be properly seated and secured according to the applicable installation procedure.

The 5 m cable is also part of the electrical configuration. The probe must be matched to the appropriate 5 m Proximitor Sensor arrangement rather than combined indiscriminately with electronics designed for a different cable length.

4.5 Multiple-approval configuration

The 05 suffix distinguishes this version from the otherwise similar model ending in 00. The multiple-approval option is intended for applicable installations requiring the relevant approval markings.

The presence of this suffix does not mean that the probe is automatically suitable for every hazardous location worldwide. The exact certificates, temperature classification, equipment marking, and installation requirements should be verified for the destination site.

4.6 Integration with monitoring equipment

The probe is a sensing component, not a standalone monitoring instrument. A typical measurement system includes the probe, compatible cable components, a Proximitor Sensor, and monitoring equipment.

The resulting signal may be used for shaft-position measurement, vibration monitoring, trend analysis, and alarm functions supported by the connected monitoring system.

Correct component matching, installation, calibration, and configuration are essential to obtaining meaningful measurements.

5. Product Applications

5.1 Steam turbines

Steam turbines may use proximity systems to monitor shaft vibration, axial position, and other machine movements specified in the monitoring design.

Measurements can help operators and maintenance personnel observe changes during start-up, changes in load, normal operation, and shutdown. The exact sensor location and measurement function depend on the turbine’s construction and monitoring requirements.

5.2 Gas turbines

Gas turbines operate under demanding mechanical and thermal conditions. Shaft-related measurements can contribute to the assessment of rotor behavior and help identify changes that warrant further investigation.

The probe should be installed only where its mechanical and environmental limits meet the requirements of the machine. The temperature rating of the complete measurement system must be considered, not just that of the probe.

5.3 Centrifugal compressors

Centrifugal compressors are used in industrial process plants, gas-processing facilities, and utility systems. Suitable proximity probes can provide shaft-position or vibration-related measurements for compatible monitoring equipment.

The resulting data can be compared with established operating trends to help maintenance teams investigate abnormal vibration, changing rotor behavior, or other machinery concerns.

5.4 Reciprocating compressors

Selected reciprocating compressor installations use proximity probes for rod-position or rod-drop measurements. Such applications require careful consideration of the measurement range, target geometry, mounting position, and the monitoring system’s configuration.

The 3300 XL 11 mm family may be relevant where the required measurement range and installation requirements are compatible with the system.

5.5 Pumps and electric motors

Large pumps and motors may require shaft-related measurements as part of a condition monitoring arrangement.

A proximity probe can provide non-contact measurements when the machine design, shaft material, mounting location, and associated electronics are suitable. The probe configuration must match the intended measurement point.

5.6 Generators and other rotating machinery

Generators and other rotating equipment may use shaft-position or vibration measurements to monitor rotor behavior.

The probe can supply measurement information to compatible electronics, allowing monitoring equipment to record changes and compare them with established operating conditions.

5.7 Industrial condition monitoring

In industrial plants, proximity measurements can contribute to condition-based maintenance programs. Trend information can help maintenance teams decide when a machine needs closer inspection.

The readings should be interpreted alongside machine speed, load, bearing conditions, temperature, and other relevant operating information. A probe measurement by itself does not identify every possible mechanical fault.

6. Product Advantages

6.1 Non-contact sensing

The probe measures the position of a suitable conductive target without requiring physical contact during normal operation. This avoids the contact wear associated with mechanical sensing devices and makes the technology suitable for rotating machinery.

6.2 Defined mechanical dimensions

The M16 × 1.5 mounting thread and 60 mm case-length option provide clear mechanical identifiers for installation planning and replacement selection.

These details help engineers compare the replacement probe with the existing installation and check whether the mounting point and available clearance are suitable.

6.3 Five-metre cable configuration

The 5.0 m cable option provides a defined connection length for installations requiring the associated electronics to be positioned away from the probe.

Maintaining the correct cable length and matching it with compatible system electronics helps preserve the intended measurement configuration.

6.4 Integration with industrial monitoring systems

The probe is designed to operate within a compatible proximity measurement system. This allows it to contribute to continuous monitoring, measurement trending, and machinery protection functions supported by the connected equipment.

6.5 Suitable for a range of rotating machinery

The 3300 XL 11 mm family can be used in several types of industrial machinery where the measurement requirements are appropriate. This includes selected turbine, compressor, and other rotating-equipment applications.

The suitability of an individual probe depends on the machine design, required measurement function, target material, mounting configuration, and environmental conditions.

6.6 Easier spare-parts identification

The complete model number identifies the selected case length, cable length, connector type, and approval option.

Recording the complete part number in a maintenance database helps prevent ordering errors, especially where several probes from the same family are installed on one machine.

6.7 Approval option for applicable installations

The multiple-approval configuration can be relevant where the installation requires the appropriate agency markings. This helps procurement personnel identify the intended approval variant.

The actual approval documents and product markings should still be checked before installation in a regulated or hazardous area.

7. Five Recommended Models from the Same Series or Related Configurations

The following options are useful for comparing case lengths, connector and cable configurations, and mounting arrangements within the same product family. They are not all direct replacements for the specified model.

Model selection guidance

330709-000-040-50-02-05 has a shorter case than the main model. It may suit an installation designed for a 40 mm case, but it should not be substituted without checking the required mounting depth and probe clearance.

330709-000-050-50-02-05 uses a 50 mm case. It is another comparison option when the installation has a different required case length.

330709-000-060-50-02-00 has the same general mechanical and cable configuration but a different approval suffix. Confirm the required approval markings before choosing it.

330709-000-060-50-12-05 uses the FluidLoc cable configuration rather than the standard cable option. The cable type and connector arrangement must match the installation requirements.

330710-000-060-50-02-05 is an armored related model. Armor may provide additional mechanical protection in suitable installations, but the external dimensions and installation clearances differ from the unarmored version.

The complete part number, cable type, mounting thread, case length, and approval requirements should be checked before purchasing any alternative.

8. Five Recommended Models from the Same Brand

8.1 330180-50-00 — Proximitor Sensor

The Proximitor Sensor is the associated electronics component used with a compatible proximity probe and cable arrangement. It provides the required interface between the probe and the monitoring equipment.

When selecting it for the 330709 probe, verify the cable-length configuration and the complete system requirements. The 5 m probe should be used with the corresponding compatible 5 m Proximitor Sensor arrangement.

8.2 330130-040-00-00 — Extension Cable

An extension cable is used to connect compatible transducer components when the installation requires a specific distance between the probe and associated electronics.

Cable length, connector type, and electrical characteristics must match the intended measurement system. The exact cable specification should be checked before ordering.

8.3 330101-00-08-10-02-00 — 8 mm Proximity Probe Configuration

The 3300 XL 8 mm family provides a related option for non-contact shaft measurement. It is relevant when the machine design and measurement requirements call for an 8 mm probe system.

The 8 mm and 11 mm families have different geometries and system characteristics. This model should not be treated as a direct replacement for the 11 mm probe without engineering verification.

8.4 3500/42M — Machinery Monitoring Module

The 3500/42M is a monitoring module intended for compatible machinery monitoring systems. It processes supported measurement inputs and performs monitoring functions according to the installed system configuration.

It serves a different role from the 330709 probe. The probe measures the target, while the monitoring module handles compatible input signals as part of the overall monitoring arrangement.

8.5 3500/22M — Rack Interface Module

The 3500/22M is an interface module used in compatible monitoring racks. It supports communication and access to rack information according to the configured system.

It is not a sensing probe and cannot replace the 330709 directly. It may be relevant when maintaining or expanding the monitoring infrastructure that receives measurements from compatible sensors.
