Introduction
The Bently Nevada 330703-000-060-10-02-05 3300 XL 11 mm Proximity Probe is a precision non-contact eddy-current probe designed for continuous monitoring of shaft vibration, displacement, and position in critical rotating machinery.
This configuration combines an M14 × 1.5 metric mounting thread, 0 mm unthreaded length, 60 mm overall case length, and a 1.0 m integral cable. The 02 configuration uses a miniature coaxial ClickLoc connector with standard cable, while the final 05 identifies the multiple-approval configuration.
The 3300 XL 11 mm platform is particularly valuable where a longer linear measurement range is needed. Typical uses include axial/thrust position, steam-turbine differential expansion, reciprocating-compressor rod position or rod drop, tachometer, zero-speed, and Keyphasor measurements.

Applications
The 330703-000-060-10-02-05 is intended for continuous, non-contact monitoring of conductive rotating targets. Its extended-range 11 mm sensing platform makes it particularly useful in applications where shaft movement must be measured accurately over a comparatively broad linear range.
Typical applications include:
-
Steam turbine shaft vibration monitoring
-
Axial/thrust position measurement
-
Steam-turbine differential expansion
-
Compressor shaft displacement
-
Reciprocating-compressor rod position
-
Rod-drop monitoring
-
Generator shaft vibration
-
Pump and motor vibration monitoring
-
Keyphasor phase-reference signals
-
Tachometer measurement
-
Zero-speed detection
-
Rotor position monitoring
-
Bearing and machinery protection
-
Online condition monitoring
The complete 3300 XL 11 mm transducer system is specified for position or vibration measurements from 0 to 8 kHz and provides a nominal 3.94 V/mm (100 mV/mil) output.
For a complete operating channel, the probe is used with the appropriate 3300 XL 11 mm extension cable and Proximitor Sensor. The probe, cable, and sensor are designed as a matched transducer system.
Advantages
Extended 11 mm Measurement Range
The 11 mm probe design offers a longer linear range than the standard 3300 XL 8 mm platform. This is a major advantage for applications involving axial position, displacement, and differential expansion.
60 mm Case Configuration
The 60 mm case provides additional physical reach compared with shorter 330703 variants. This can be useful when the available mounting arrangement requires a longer probe body.
Metric M14 × 1.5 Thread
The M14 × 1.5 mounting thread makes this probe a natural fit for machinery using metric mounting hardware and provides a clean mechanical installation.
1-Meter Integral Cable
The 1.0 m integral cable gives practical routing distance between the probe and extension-cable connection without requiring field modification of the sensing assembly.
Secure ClickLoc Connection
The ClickLoc connector is designed to lock into position and help prevent the connection from loosening during machinery operation. The 02 option provides the standard connector arrangement without the separate connector protector specified by option 01.
Multiple-Approval Configuration
The final 05 suffix identifies the multiple-approval option. This makes the configuration attractive for projects where the machinery installation requires the applicable agency-approved version of the 3300 XL 11 mm probe family.
Durable Construction
The probe uses an AISI 304 stainless-steel case and PPS tip material. The probe cable uses a 75 Ω triaxial FEP-insulated construction, providing a robust package for industrial machinery monitoring.
Non-Contact Sensing
Eddy-current technology measures shaft movement without physical contact. This avoids mechanical wear at the sensing point and makes the technology well suited to high-speed rotating equipment.
Proven Machinery-Monitoring Architecture
The 3300 XL 11 mm system integrates the probe with its extension cable and Proximitor Sensor to provide a complete displacement and vibration measurement chain. This architecture is well suited to critical machinery protection and condition-monitoring applications.
Technical FAQs
1. What is the Bently Nevada 330703-000-060-10-02-05?
It is a 3300 XL 11 mm Proximity Probe featuring an M14 × 1.5 thread, 60 mm case length, 1.0 m integral cable, standard ClickLoc connector, and multiple agency approvals.
2. What does 330703 indicate?
The 330703 base model identifies the metric M14 × 1.5, unarmored 3300 XL 11 mm probe configuration.
3. What does “000” mean?
The 000 section specifies a 0 mm unthreaded length. Metric 3300 XL probes use length increments defined by the ordering system.
4. What does “060” mean?
The 060 section identifies the 60 mm overall case length.
5. How long is the integral cable?
The 10 option specifies a 1.0 m (3.3 ft) integral cable.
6. What connector does this model use?
The 02 option specifies a miniature coaxial ClickLoc connector with standard cable. Option 01 is the similar configuration with an additional connector protector.
7. What does the final “05” mean?
The final 05 identifies the Multiple Approvals configuration. The alternative 00 option means that agency approval is not required.
8. What is the recommended probe gap?
The standard 3300 XL 11 mm system uses a nominal 2.5 mm (100 mil) gap under the specified calibration conditions.
9. What is the linear measurement range?
The 3300 XL 11 mm transducer system provides approximately 4 mm (160 mil) of linear measurement range, with a nominal scale factor of 100 mV/mil (3.94 V/mm).
10. Can this probe replace a 330703-000-060-10-02-00?
Mechanically, both configurations share the same basic M14 × 1.5, 60 mm, 1 m, ClickLoc arrangement. However, the final suffix differs: 05 is the multiple-approval version, while 00 is the version without an agency-approval option. Replacement selection should therefore account for the hazardous-area and certification requirements of the actual installation.
