Product Overview
In critical industrial environments, accurate monitoring of rotating equipment is essential for preventing unexpected failures and improving maintenance efficiency. The Bently Nevada 330701-00-40-10-12-05 3300 XL 11 mm Eddy Current Probe is a non-contact displacement sensor designed for high-performance machinery vibration monitoring and protection applications.
The probe uses advanced eddy current sensing technology to measure the relative distance between the probe tip and a conductive rotating shaft surface. By detecting changes in the electromagnetic field, the sensor converts shaft movement into electrical signals that can be analyzed by machinery monitoring systems.
The 3300 XL 11 mm Eddy Current Probe is widely used in critical rotating equipment where continuous monitoring of shaft vibration, position, and mechanical condition is required. Typical applications include steam turbines, gas turbines, compressors, generators, pumps, and other large industrial machines.
The Bently Nevada 330701-00-40-10-12-05 features a 1-meter total cable length configuration, providing flexible installation options for machinery protection systems while maintaining accurate signal transmission.

Function and Working Principle
The Bently Nevada 330701-00-40-10-12-05 operates using eddy current measurement technology.
The probe generates a high-frequency electromagnetic field at the sensing tip. When the rotating shaft moves closer to or farther away from the probe, the electromagnetic characteristics change. These changes are converted into electrical signals representing the shaft displacement.
The monitoring system uses these signals to evaluate machine operating conditions and identify abnormal mechanical behavior.
1. Non-Contact Shaft Measurement
The probe measures shaft movement without physical contact.
This provides several advantages:
- No mechanical wear between sensor and shaft
- Suitable for high-speed rotating equipment
- Continuous online monitoring capability
- Stable measurement performance during operation
2. Vibration Monitoring Function
The probe provides accurate vibration measurement data for machinery protection.
It helps monitor:
- Rotor imbalance
- Shaft misalignment
- Mechanical looseness
