Product Overview
The 330101-00-28-90-02-00 belongs to the Bently Nevada 3300 XL 8 mm eddy current proximity probe series. This non-contact sensor measures shaft radial vibration, shaft position and rotor axial displacement on rotating machinery by detecting changes in eddy current fields between the probe tip and conductive target surfaces. It eliminates mechanical contact wear issues common with contacting measurement devices and delivers continuous real-time dynamic data to monitoring systems. Vibration analysts, turbomachinery maintenance teams and DCS system integrators rely on this probe for reliable condition monitoring of critical rotating equipment. The 90-degree elbow cable construction simplifies installation inside tight bearing housings and confined machinery enclosures.
Application Scenarios
- Steam & Gas Turbine Monitoring: Installed at bearing housings to capture shaft radial vibration data. Continuous measurement enables early detection of unbalance, misalignment and bearing degradation to prevent catastrophic turbine failures.
- Centrifugal Compressor Condition Surveillance: Tracks rotor vibration and shaft position for petrochemical and gas processing compressors. The wide operating temperature range accommodates high-temperature compressor casing environments.
- Industrial Generator Sets: Monitors generator rotor vibration and gap variation. Measurement signals feed into online machinery protection systems to trigger alarms or automatic trips when vibration thresholds are exceeded.
