Introduction
The Bently Nevada 330703-000-060-10-02-00 3300 XL 11 mm Proximity Probe is a precision non-contact displacement sensor designed for demanding rotating-machinery monitoring applications. As part of the 3300 XL 11 mm Proximity Transducer System, it is used to detect shaft vibration, displacement, position, and other dynamic movements without physical contact with the monitored shaft.
This particular configuration is built around an M14 × 1.5 metric mounting thread, a 60 mm overall case length, 0 mm unthreaded length, and a 1.0 m integral cable. The probe uses a miniature coaxial ClickLoc connector with standard cable, while the final 00 designates the configuration without an additional agency-approval option.
The larger 11 mm probe tip provides a longer linear measurement range than the standard 3300 XL 8 mm system, making this model particularly attractive for applications such as axial position, steam-turbine differential expansion, reciprocating-compressor rod position, tachometer, zero-speed, and Keyphasor measurements.

The 3300 XL 11 mm system is specifically intended for applications in which its longer linear range is beneficial. Bently Nevada's system description highlights axial/thrust position, steam-turbine ramp differential expansion, reciprocating-compressor rod position or rod drop, tachometer/zero-speed, and Keyphasor applications.
For complete operation, the probe forms one part of a matched transducer chain consisting of the 3300 XL 11 mm probe, 3300 XL 11 mm extension cable, and 3300 XL 11 mm Proximitor Sensor.
Advantages
Extended Measurement Range
The 11 mm sensing platform offers a longer linear range than the standard 3300 XL 8 mm system. This makes the 330703 family especially valuable for machinery applications where shaft displacement or axial movement requires additional measurement range.
60 mm Probe Configuration
The 60 mm case length gives this version a longer physical configuration than 40 mm and 50 mm variants. It can be an excellent choice when the machinery mounting arrangement requires additional probe body length.
Metric M14 × 1.5 Mounting
The metric M14 × 1.5 thread provides straightforward installation into compatible metric probe mounting locations and is well suited to machinery using metric mechanical standards.
1-Meter Integral Cable
The factory-integrated 1.0 m cable gives installers practical routing distance from the sensing location to the extension-cable connection while maintaining a clean, standardized assembly.
ClickLoc Connector
The miniature coaxial ClickLoc connector provides a purpose-built interface between the probe and extension cable. The 02 configuration is the standard ClickLoc arrangement without the additional connector protector used by option 01.
Robust Industrial Materials
The probe case uses AISI 304 stainless steel, while the probe tip uses polyphenylene sulfide (PPS). These materials provide a durable mechanical package suitable for industrial machinery installations.
Non-Contact Technology
Eddy-current sensing allows the probe to monitor shaft movement without touching the rotating surface. This eliminates wear at the sensing interface and makes the technology well suited to high-speed rotating equipment.
Broad Machinery Coverage
A single 3300 XL 11 mm platform can support vibration, displacement, axial position, phase-reference, tachometer, and zero-speed measurements, providing useful flexibility for machinery-monitoring projects.
Straightforward Replacement Identification
The complete 330703-000-060-10-02-00 code clearly identifies the mechanical and electrical configuration. This reduces the risk of selecting an apparently similar probe with an incompatible case length, connector, cable, or approval configuration.
Technical FAQs
1. What is the Bently Nevada 330703-000-060-10-02-00?
It is a 3300 XL 11 mm Proximity Probe with an M14 × 1.5 thread, 60 mm case length, 1.0 m integral cable, standard ClickLoc connector, and no additional agency approval option.
2. What does the 330703 model number indicate?
The 330703 base model identifies the metric M14 × 1.5, unarmored 3300 XL 11 mm probe family.
3. What does “000” mean?
The 000 portion specifies a 0 mm unthreaded length.
4. What does “060” mean?
The 060 portion specifies the 60 mm overall case length.
5. How long is the integral cable?
The 10 configuration provides a 1.0 m (3.3 ft) total integral cable length.
6. What connector does this probe use?
The 02 option specifies a miniature coaxial ClickLoc connector with standard cable.
7. Does this version have special agency approvals?
No additional approval option is selected. The final 00 identifies the “Not required” agency-approval configuration.
8. What is the recommended target size?
A reference specification for the 3300 XL 11 mm system gives a recommended minimum target size of approximately 30.5 mm (1.2 in) diameter for a flat target.
9. What is the nominal output sensitivity?
The 3300 XL 11 mm transducer system provides approximately 3.94 V/mm (100 mV/mil) output for non-contact vibration and displacement measurements.
10. Can the 60 mm probe replace a shorter 330703 probe?
Only after confirming the mechanical installation. Although several 330703 models share the same M14 × 1.5 thread, the case length, unthreaded length, cable configuration, connector option, and approvals can differ. A 60 mm probe should therefore be selected only when its physical dimensions match the existing installation.
