Introduction
The Bently Nevada 330707-00-62-10-01-00 is a 3300 XL 11 mm Proximity Probe designed for reliable, non-contact measurement of shaft vibration and displacement on critical rotating machinery. It belongs to the 330707 series, which uses a 5/8-18 UNF thread and unarmored construction.
This particular configuration is built around a 6.2-inch overall case length, 1.0 m integral cable, and a miniature coaxial ClickLoc connector with connector protector. The extended case makes it a practical choice for deeper mounting arrangements, while the 11 mm sensing tip provides the approximately 4 mm (160 mil) linear range associated with the 3300 XL 11 mm transducer system.
For industrial maintenance teams, this model offers a strong combination of long-reach mechanical geometry, non-contact sensing, and flexible machinery-monitoring capability. It can be integrated with the appropriate 3300 XL 11 mm extension cable and Proximitor Sensor as part of a complete measurement chain.

Applications
Turbine Shaft Monitoring
The 3300 XL 11 mm system is widely suited to critical turbine applications requiring accurate shaft vibration and displacement measurement. Its non-contact design allows continuous monitoring without mechanical contact with the rotating shaft.
Radial Vibration Measurement
The probe can be positioned radially against a suitable shaft target to monitor vibration and shaft position. The 11 mm sensing tip provides the extended measurement range needed for applications where an 8 mm system may not provide sufficient reach.
Axial Position Monitoring
The 3300 XL 11 mm platform is designed for applications including axial or thrust-position measurement, making it useful for monitoring critical rotor movement.
Differential Expansion
Compatible 3300 XL 11 mm arrangements can be used for ramp differential-expansion measurements on steam turbines, where relative movement between rotor and stator is important.
Reciprocating Compressor Monitoring
The system can support suitable rod-position and rod-drop measurements on reciprocating compressors, where the longer sensing range is especially useful.
Keyphasor Applications
The probe can be integrated into suitable Keyphasor arrangements to provide a phase reference for synchronous vibration analysis and rotational-speed measurement.
Deep-Mount Installations
The 6.2-inch case length makes this model particularly attractive for applications requiring a longer probe body or deeper mounting position than shorter 330707 configurations can provide.
Machinery Protection Systems
When paired with the correct 3300 XL 11 mm Proximitor Sensor and extension cable, the probe can form part of a complete monitoring system used for alarm, trending, diagnostic, and machinery-protection functions.
Advantages
Extended 6.2-Inch Case
The 6.2-inch case gives this model a substantial reach compared with shorter 2.5-, 3.0-, or 4.0-inch versions. It is a useful choice when the physical installation requires additional probe length.
11 mm Sensing Tip
The 11 mm tip provides a nominal 4 mm linear measurement range, offering more reach than the standard 3300 XL 8 mm system.
5/8-18 UNF Thread
The 5/8-18 UNF mounting interface makes this model suitable for compatible imperial-thread machinery installations.
Connector Protector
The 01 connector option includes a ClickLoc connector protector, helping safeguard the connection area during installation and service.
Non-Contact Technology
Eddy-current measurement provides accurate shaft displacement information without physical contact. This makes the technology well suited to continuously operating rotating equipment.
1 m Integral Cable
The 1.0 m cable provides a convenient connection length for installations where the Proximitor Sensor is positioned relatively close to the probe location.
Stainless Steel Construction
The probe case uses AISI 304 stainless steel, providing a durable mechanical housing for demanding industrial environments.
Wide Application Range
One 3300 XL 11 mm system can support radial vibration, position, axial position, Keyphasor, tachometer, and other compatible measurements.
Strong Replacement Potential
For an existing 330707 installation, matching the complete 00-62-10-01-00 configuration provides a more dependable replacement strategy than choosing a probe based solely on its 11 mm diameter.
Technical FAQs
1. What is the Bently Nevada 330707-00-62-10-01-00?
It is a 3300 XL 11 mm Proximity Probe using a 5/8-18 UNF thread, unarmored construction, 6.2-inch case, 1 m cable, and ClickLoc connector with protector.
2. What does the 62 option specify?
The 62 option specifies a 6.2-inch overall case length, equivalent to approximately 157.5 mm.
3. What does the first 00 mean?
The first 00 identifies a 0-inch unthreaded length. The 3300 XL ordering system allows the unthreaded section to be selected separately from overall case length.
4. What mounting thread does this probe use?
The 330707 family uses a 5/8-18 UNF thread and is the unarmored version of the 3300 XL 11 mm probe family.
5. How long is the integral cable?
The 10 configuration specifies a 1.0 m (3.3 ft) cable.
6. What does the 01 connector option mean?
The 01 option specifies a miniature coaxial ClickLoc connector with connector protector and standard cable.
7. Is this probe armored?
No. The 330707 is an unarmored 5/8-18 UNF probe. The corresponding armored 5/8-18 UNF family is 330708.
8. What is the linear measurement range?
The 3300 XL 11 mm system provides a nominal 4 mm (160 mil) linear range and a nominal output scale factor of 3.94 V/mm (100 mV/mil).
9. What is the operating frequency range?
The 3300 XL 11 mm transducer system is designed for position or vibration measurements across approximately 0 to 8 kHz.
10. Can this model replace a shorter 330707 probe?
Not automatically. Although the probes may share the same 5/8-18 UNF mounting family, the 6.2-inch case length changes the installation geometry. Clearance, insertion depth, target position, cable routing, and the original probe's complete ordering code should be verified before substitution.
