Industrial-Grade Precision Monitoring for Critical Rotating Assets
The Bently Nevada 330101-00-79-10-02-05 3300 XL 8 mm Proximity Probe is a high-reliability eddy-current sensor engineered for continuous, non-contact measurement of shaft vibration, displacement, and position in rotating machinery. As part of the industry-standard 3300 XL proximity system, it delivers stable signal performance, strong environmental tolerance, and long service life in demanding industrial applications.
This configuration (…79-10-02-05) is typically associated with a 7.9-inch class probe geometry and a 1.0-meter system cable with standard ClickLoc connector and agency-approved configuration, making it suitable for turbomachinery installations requiring extended probe reach and certified industrial deployment. It is widely used in condition monitoring systems where accuracy and long-term stability directly impact operational safety and uptime.
Built with stainless steel housing and a PPS sensing tip, the probe is designed to maintain consistent performance under high vibration, temperature variation, and harsh process environments.
