Product Introduction
When vibration monitoring demands robust probe performance, the Bently Nevada 330191-00-33-15-CN 3300 XL 8 mm ETR probe delivers patented TipLoc and CableLoc designs to prevent probe tip detachment and cable failure. This industrial automation module is built for severe-service environments, featuring a 3/8-24 UNF thread without armor and a total length of 1.5 metres (4.9 feet). The 3300 XL series improves over previous designs with a stronger bond between the probe tip and body, plus a cable that withstands 330 N (75 lbf) pull strength.

Industry Applications
The Bently Nevada 330191-00-33-15-CN is ideal for vibration monitoring on turbines, compressors, pumps, and fans in power generation, oil and gas, and manufacturing facilities. Its 8 mm diameter provides a thicker PPS encapsulation for superior coil protection, while the larger case offers enhanced physical robustness against abuse. The FluidLoc cable option prevents oil leakage from machines, making it suitable for lubricated rotating equipment.
Maintenance & Reliability
Built with a patented TipLoc molding method and CableLoc design, the Bently Nevada 330191-00-33-15-CN minimizes common failure points such as probe tip separation and cable pull-out. The Viton O-ring seals differential pressure between the tip and case, reducing the need for frequent recalibration. Operate within the specified temperature schedule to maximize service life—for T1 classification, ambient temperature can range from -55°C to +232°C.
Selection Guide & Purchasing Advice
Before ordering the Bently Nevada 330191-00-33-15-CN, verify the required thread (3/8-24 UNF), total length option (1.5 m), and agency approval (CN=Country Specific Approval). This module is supplied new in factory packing with a 12-month warranty. For reliable sourcing and fast delivery, choose PLC Source PRO for your industrial automation spares.
