Product Overview
The Bently Nevada 330173-00-04-20-02-05 3300 5 mm Proximity Probe is a precision non-contact displacement sensor designed for continuous monitoring of rotating machinery shaft vibration, displacement position, and mechanical operating conditions.
As a member of the Bently Nevada 3300 5 mm Proximity Probe family, this sensor is widely used in industrial machinery protection, predictive maintenance, and condition monitoring systems. It provides accurate measurement of shaft movement by detecting changes in the gap between the probe tip and the rotating shaft surface.
The Bently Nevada 330173-00-04-20-02-05 model features a 5 mm sensing tip, a total length of 2 meters, and a weight of approximately 0.646 kg. The extended length design provides greater installation flexibility for large industrial equipment where the measurement point is located away from the monitoring system.
With eddy current sensing technology, this proximity probe enables reliable non-contact measurement without mechanical contact with rotating components. It helps improve equipment reliability, support early fault detection, and optimize maintenance planning for critical machinery.

Working Principle
The Bently Nevada 330173-00-04-20-02-05 Proximity Probe operates through eddy current sensing technology to measure shaft displacement and vibration without direct physical contact.
The probe generates an electromagnetic field around the sensing tip. When the rotating shaft moves due to vibration, imbalance, misalignment, thermal expansion, or other mechanical changes, the distance between the shaft surface and the probe changes.
The sensor detects these variations and converts them into electrical signals representing shaft movement and operating conditions.
The measurement process includes:
- Generating an electromagnetic sensing field
- Detecting changes in shaft position
- Converting displacement changes into electrical signals
- Transmitting monitoring information to protection systems
This technology provides:
- Accurate shaft displacement measurement
- Continuous vibration monitoring
- Stable signal output
- Reliable operation in industrial environments
