330105-02-12-20-02-00 Full Technical Overview


1. Product Title

330105-02-12-20-02-00 3300 XL 8 mm Reverse Mount Proximity Probe


2. Brand

This product belongs to a globally recognized industrial condition monitoring and machinery protection technology brand widely used in vibration monitoring, shaft displacement measurement, and predictive maintenance systems for rotating equipment.


3. Product Series

3300 XL 8 mm Proximity Transducer System (Reverse Mount Type)

This series is designed for high-accuracy non-contact measurement of shaft vibration and position in critical rotating machinery such as turbines, compressors, pumps, and motors.


4. Product Introduction

The 330105-02-12-20-02-00 is an 8 mm reverse mount proximity probe designed for continuous monitoring of rotating machinery conditions.

It uses eddy current sensing technology, which measures distance variations between the probe tip and conductive metal shaft surfaces without physical contact.

The reverse mount structure is intended for installations with limited axial space or where conventional mounting is not suitable.

This probe is typically used as part of a full 3-component system:

  • Proximity probe
  • Extension cable
  • Proximitor signal conditioning module

Together, they provide stable and accurate vibration monitoring for machinery protection and predictive maintenance.
