Stable High-Accuracy Monitoring for Critical Rotating Machinery
The Bently Nevada 330101-02-24-10-02-05 3300 XL 8 mm Proximity Probe is a precision eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and position in industrial rotating equipment. As part of the trusted 3300 XL proximity transducer system, it delivers stable signal output, high repeatability, and long-term durability in demanding operational environments.
This configuration is commonly associated with a 2.4-inch class probe case length and a 1.0-meter system cable with ClickLoc connector and standard approval configuration, making it suitable for a wide range of turbomachinery and general-purpose industrial monitoring applications. It is widely used in condition monitoring systems where measurement accuracy and mechanical reliability are essential for safe and efficient operation.
Built with stainless steel housing and a PPS (Polyphenylene Sulfide) sensing tip, this probe is engineered for harsh industrial environments involving vibration, temperature fluctuation, and continuous operation.
