Product Overview
The Bently Nevada 330196-05-30-50-05 3300 XL 8 mm ETR Reverse Mount Probe is a high-precision proximity sensor designed for continuous condition monitoring of critical rotating machinery. It provides accurate non-contact measurement of shaft vibration, displacement, and position, making it an important component in industrial machinery protection and predictive maintenance systems.
As part of the 3300 XL 8 mm Extended Temperature Range (ETR) Reverse Mount Probe series, the Bently Nevada 330196-05-30-50-05 is engineered for applications requiring reliable performance, extended cable length, and flexible installation options in demanding industrial environments.
The probe uses eddy current proximity sensing technology to measure the distance between the probe tip and the rotating shaft surface. Changes in shaft movement are converted into electrical signals, which can be analyzed by monitoring systems to evaluate machine health and detect abnormal operating conditions.
The reverse mount design allows installation in machinery where standard probe mounting methods are difficult due to limited space, mechanical structure restrictions, or special equipment configurations.
The Bently Nevada 330196-05-30-50-05 configuration includes:
With its extended 5-meter cable length, this proximity probe is suitable for large industrial equipment where the monitoring system is installed away from the measurement point.

Function and Working Principle
The Bently Nevada 330196-05-30-50-05 operates using eddy current measurement technology, providing accurate shaft monitoring without physical contact.
During operation, the probe generates a high-frequency electromagnetic field around the sensing tip. When the rotating shaft moves closer or farther from the probe, the electromagnetic field changes. These changes are converted into electrical signals proportional to shaft position and vibration.
The measurement process includes:
- Creating an electromagnetic sensing field
- Detecting shaft displacement changes
- Measuring probe-to-shaft distance
- Converting mechanical movement into electrical output
- Sending condition monitoring signals 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 allows operators and maintenance engineers to identify potential equipment problems before serious failures occur.
