Product Overview
In modern industrial plants, reliable monitoring of rotating machinery is essential for preventing equipment failures, improving operational efficiency, and extending machine service life. The Bently Nevada 330195-02-12-05-CN 3300 XL 8 mm ETR Reverse Mount Probe is a precision proximity probe designed for non-contact measurement of shaft vibration, displacement, and position in critical rotating equipment.
The Bently Nevada 330195-02-12-05-CN belongs to the 3300 XL 8 mm Extended Temperature Range (ETR) Reverse Mount Probe series. This probe is designed for applications where installation flexibility, high measurement accuracy, and reliable operation in demanding industrial environments are required.
Using advanced eddy current sensing technology, the probe detects variations in the distance between the probe tip and the rotating shaft surface. These changes are converted into electrical signals that provide important information about shaft movement, vibration behavior, and equipment operating conditions.
The reverse mount design allows the probe to be installed in applications where traditional front-mounted proximity probes cannot be easily installed due to mechanical limitations or restricted access.
The Bently Nevada 330195-02-12-05-CN configuration includes:
This proximity probe is commonly applied in turbines, compressors, generators, pumps, motors, and other high-value rotating machinery requiring continuous condition monitoring.
With a total length of 0.5 meters and a weight of 0.162 kg, the Bently Nevada 330195-02-12-05-CN provides a compact and reliable solution for industrial machinery protection and predictive maintenance systems.

Function and Working Principle
The Bently Nevada 330195-02-12-05-CN operates based on eddy current proximity measurement technology, providing accurate and reliable non-contact shaft monitoring.
During operation, the probe creates an electromagnetic field around the sensing tip. When the rotating shaft moves relative to the probe, the distance variation changes the electromagnetic field intensity. The system converts these changes into electrical output signals that represent shaft displacement and vibration characteristics.
The working process includes:
- Creating an electromagnetic sensing field
- Detecting changes in shaft position
- Measuring probe-to-shaft clearance
- Converting mechanical movement into electrical signals
- Delivering monitoring data to protection systems
The probe is capable of monitoring:
- Radial shaft vibration
- Axial shaft displacement
- Rotor position changes
- Mechanical clearance variations
- Rotating equipment operating conditions
This enables early identification of abnormal machine behavior and supports predictive maintenance strategies.
