330101-00-08-10-11-CN | Bently Nevada 8 mm Probe 1.0 m Cable

What Is the 330101-00-08-10-11-CN?

When machine vibration threatens uptime, the 330101-00-08-10-11-CN from Bently Nevada delivers precise displacement measurement. This 3300 XL 8 mm probe uses a 3/8-24 UNF thread and comes without armor. Its 1.0 metre (3.3 feet) total length includes a miniature coaxial ClickLoc connector with connector protector and FluidLoc cable. The patented TipLoc molding method creates a robust bond between the probe tip and body, while the CableLoc design provides 330 N (75 lbf) pull strength. This probe is made in the U.S.A. and carries agency approval option CN for country-specific certifications.

A distinctive spec is the patented FluidLoc cable option that prevents oil and other liquids from leaking out of the machine through the cable interior. This feature directly reduces maintenance calls and fluid loss in rotating machinery.

Real-World Applications

Maintenance engineers rely on the 330101-00-08-10-11-CN for radial vibration monitoring in turbines, compressors, and pumps. Its 2 mm linear range covers the typical vibration gap of -9 Vdc (approximately 1.27 mm). The 7.87 V/mm scale factor provides consistent readings across temperature changes from 0°C to +45°C. In addition, the rugged PPS tip and stainless steel case withstand harsh industrial environments. For example, a petrochemical plant can use this probe to detect early bearing wear before unplanned shutdowns occur.

Installation Guide

Mount the probe using the 3/8-24 UNF thread into a standard mounting hole. Ensure the target surface is clean and within the linear range of 0.25 to 2.3 mm (10 to 90 mils). For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. The maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Always follow the manufacturer's manual for proper gap setting to -9 Vdc.

Maintenance and Reliability

Regularly inspect the probe cable and connector for wear or damage. The FluidLoc cable option reduces the risk of oil leaks, lowering fluid replacement costs over time. Because the probe is not pressure tested before shipment, verify the pressure seal if your application involves differential pressure. The Viton O-ring seals the probe tip to the case. For extended temperature ranges, the probe tip withstands up to +218°C (+425°F). Routine checks of the probe resistance (7.59 ±0.50 Ω for 1.0 m length) help confirm integrity.
