Reliable High-Precision Sensing for Demanding Rotating Machinery
The Bently Nevada 330101-30-60-10-02-00 3300 XL 8 mm Proximity Probe is a robust eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, displacement, and axial position in industrial rotating equipment. As part of the widely trusted 3300 XL system, it delivers stable signal output, high accuracy, and long-term durability in harsh operating environments where machinery protection is critical.
This configuration (30-60-10-02-00) is generally associated with a 3.0-inch class probe geometry, 6.0-inch case length, 1.0-meter system cable, ClickLoc connector, and standard non-certified configuration option, making it suitable for installations that require extended mechanical reach and deeper probe insertion into bearing housings or turbine assemblies. Based on 3300 XL system ordering conventions, the “30-60” variant is commonly selected for heavy-duty machinery monitoring where rigid mounting and stable clearance alignment are required.
Built with stainless steel housing and a PPS sensing tip, the probe is engineered for high resistance to vibration, thermal cycling, and industrial contamination while maintaining consistent measurement performance.
