High-Performance Precision Sensing for Critical Rotating Machinery
The Bently Nevada 330101-13-37-10-12-05 3300 XL 8 mm Proximity Probe is a robust eddy-current transducer designed for continuous, non-contact measurement of shaft vibration, displacement, and position in high-value rotating equipment. As part of the trusted 3300 XL series, it delivers stable signal output, strong electrical noise immunity, and long-term measurement consistency in demanding industrial environments.
This configuration (…13-37-10-12-05) is commonly associated with a 1.3-inch class probe geometry, 3.7-inch case length, 1.0-meter system cable, 1.2-inch mounting configuration variant, and agency-approved industrial certification option, making it suitable for heavy-duty turbomachinery installations requiring deeper probe insertion and reinforced mechanical stability. It is widely applied in predictive maintenance systems where precision and uptime directly affect plant safety and productivity.
Constructed with stainless steel housing and a PPS sensing tip, the probe is engineered to withstand vibration stress, corrosive environments, and continuous 24/7 industrial operation.
