Product Overview
When a vibration monitoring system requires reliable displacement measurement, the Bently Nevada 330191-00-40-10-05 provides robust performance with patented durability features. This 3300 XL 8 mm ETR probe includes a thicker encapsulation of the probe coil in molded PPS plastic for enhanced ruggedness. The patented TipLoc molding method creates a stronger bond between the probe tip and body, while the CableLoc design delivers 330 N (75 lbf) pull strength to prevent cable detachment.

Applications
The Bently Nevada 330191-00-40-10-05 is ideal for measuring shaft vibration and displacement in turbines, compressors, pumps, and other rotating machinery. Its 8 mm diameter provides thicker encapsulation for extra protection against physical abuse. The optional FluidLoc cable prevents oil leakage, making it suitable for lubricated environments. With CSA, ATEX, and IECEx approvals, this probe meets global safety standards for hazardous areas.
Installation Guidance
When installing the Bently Nevada 330191-00-40-10-05, ensure the probe thread engages no more than 0.563 in (3/8-24 UNF). Tighten the connector to 0.565 N•m (5 in•lbf). The Viton O-ring provides a differential pressure seal between probe tip and case. For 1.0 m total length systems, no extension cable is required. Verify that the probe case is securely mounted to avoid vibration loosening.
Maintenance & Reliability
The probe’s robust design minimizes maintenance needs. Temperature classifications allow operation from -55°C to +232°C depending on rating. Regularly inspect the cable and connectors for signs of wear. The gold-plated connectors resist corrosion. The thick PPS tip and stainless steel case withstand harsh industrial environments. Routine checks ensure long-term reliability.
Buying Guide
When ordering, verify the unthreaded length (00 = 0.0 in), overall case length (40 = 4.0 in), total length (10 = 1.0 meter), and agency approval (05 = CSA, ATEX, IECEx). PLC Source PRO supplies new original units in factory packing with a 12-month warranty.
