Compact Metric Eddy Current Probe for Precision Shaft Vibration and Position Monitoring
The Bently Nevada 330103-00-06-05-02-02 3300 XL 8 mm Proximity Probe is a high-precision, non-contact displacement sensor designed for monitoring rotating machinery shaft vibration, radial displacement, and axial position. It is part of the proven 3300 XL 8 mm Proximity Transducer System, using eddy current sensing technology to provide reliable machine protection and condition monitoring.
The 330103 series is the metric-thread, non-armored version of the 3300 XL 8 mm probe family. This specific configuration features an M10 × 1 thread, 60 mm overall case length, 0.5-meter cable, miniature coaxial ClickLoc™ connector with standard cable, and a special agency approval option (-02 suffix configuration).

Applications
The 330103-00-06-05-02-02 proximity probe is commonly used for monitoring critical rotating equipment, including:
-
Steam turbines
-
Gas turbines
-
Centrifugal compressors
-
Generators
-
Large industrial motors
-
Pumps
-
Gearboxes
-
Turboexpanders
-
Refinery and petrochemical machinery
-
Power generation equipment
The probe measures the gap between the probe tip and the rotating shaft surface, allowing the monitoring system to detect:
-
Shaft vibration
-
Rotor displacement
-
Shaft eccentricity
-
Thrust position
-
Mechanical faults developing in rotating equipment
Key Features and Benefits
Metric M10 × 1 Thread Design
Provides compatibility with machinery manufactured using metric mounting standards.
Compact 60 mm Probe Body
The 60 mm case length provides installation flexibility where a longer probe body is required but space remains limited.
0.5 Meter Cable
Suitable for installations where the Proximitor Sensor or extension connection point is located close to the machine.
ClickLoc™ Connector
Provides a secure, vibration-resistant electrical connection for industrial environments.
Non-Contact Measurement
Eddy current technology eliminates mechanical wear because the probe does not physically contact the rotating shaft.
3300 XL System Compatibility
Works with compatible 3300 XL Extension Cables and 3300 XL Proximitor Sensors to create a complete machinery protection system.
Frequently Asked Questions
1. What is the Bently Nevada 330103-00-06-05-02-02 used for?
It is used to measure shaft vibration, radial displacement, and axial position on rotating machinery using eddy current technology.
2. Is this an armored probe?
No. The 330103 series is a non-armored metric probe. Armored metric versions belong to the 330104 series.
3. What thread does this probe use?
It uses an M10 × 1 metric thread.
4. What does the "06" represent?
The 06 option indicates a 60 mm overall case length.
5. What does the "05" cable option indicate?
The 05 option indicates a 0.5-meter (1.6 ft) total cable length.
6. What connector is used?
It uses a miniature coaxial ClickLoc™ connector with standard cable.
7. What additional components are needed?
A complete system normally requires:
-
3300 XL Proximity Probe
-
Compatible extension cable (if required)
-
3300 XL Proximitor Sensor
8. Where is it typically installed?
It is commonly installed on turbine, compressor, generator, and other high-value rotating machinery where continuous shaft monitoring is required.
