Product Overview
The Bently Nevada 330196-05-30-10-RU 3300 XL 8 mm ETR Reverse Mount Probe is a high-performance proximity measurement device designed for accurate non-contact monitoring of rotating machinery. It is widely used in industrial equipment protection systems for measuring shaft vibration, displacement, and position.
The probe is part of the 3300 XL 8 mm Extended Temperature Range (ETR) Reverse Mount Probe series, which is designed for applications requiring reliable performance under demanding industrial conditions. The reverse mount configuration provides installation flexibility in machines where standard probe mounting methods are not suitable.
The Bently Nevada 330196-05-30-10-RU uses eddy current sensing technology to detect the distance between the probe tip and the rotating shaft surface. The measured displacement changes are converted into electrical signals and transmitted to machinery monitoring systems for condition analysis and protection.
This proximity probe is commonly installed on critical rotating equipment such as turbines, compressors, generators, pumps, motors, and other high-value industrial machinery.
The Bently Nevada 330196-05-30-10-RU configuration includes:
The probe provides reliable shaft monitoring performance and supports predictive maintenance strategies by helping operators detect abnormal vibration and mechanical conditions before equipment failure occurs.

Function and Working Principle
The Bently Nevada 330196-05-30-10-RU operates based on eddy current proximity measurement technology. Unlike contact sensors, the probe measures shaft movement without physical contact, reducing mechanical wear and improving long-term reliability.
During operation:
- The probe generates an electromagnetic field around the sensing tip.
- The rotating shaft changes the electromagnetic field according to its distance from the probe.
- The system converts these changes into proportional electrical signals.
- The monitoring system analyzes the signals to determine vibration and shaft position conditions.
The probe can measure:
- Radial shaft vibration
- Axial shaft displacement
- Rotor position changes
- Mechanical clearance variations
- Rotating equipment operating conditions
This measurement capability allows maintenance teams to identify issues such as imbalance, misalignment, bearing problems, and abnormal shaft movement.
