Product Overview
Compact Metric Design with Proven 3300 XL Technology
The 330103-00-03-05-02-05 converts the distance between the probe tip and the rotating shaft surface into a proportional electrical signal. This enables accurate measurement of both dynamic vibration movement and static shaft position changes, supporting advanced machinery protection and predictive maintenance programs.
The probe is typically installed as part of a complete 3300 XL 8 mm Proximity Transducer System, which includes:
-
3300 XL 8 mm Proximity Probe
-
3300 XL Extension Cable
-
3300 XL Proximitor® Sensor
This complete system provides dependable vibration and position monitoring for fluid-film bearing machines, turbines, compressors, pumps, and other rotating assets.

Product Advantages
Metric Mounting Flexibility
The M10 x 1 metric thread allows direct installation on equipment using international mechanical standards, making the probe highly suitable for global OEM applications.
High-Accuracy Non-Contact Measurement
The eddy current sensing principle eliminates mechanical contact with the rotating shaft, reducing wear while providing continuous and repeatable measurement performance.
Compact 30 mm Probe Body
The 30 mm overall case length provides installation flexibility where mounting space is limited while maintaining the sensing performance of the 3300 XL 8 mm platform.
Industrial-Grade Construction
The stainless-steel probe housing and PPS sensing tip provide excellent resistance to temperature variation, vibration, and industrial operating conditions.
Hazardous Area Compatibility
The Option 05 approval configuration supports installations requiring CSA, ATEX, and IECEx certification for industrial hazardous locations.
