Industrial Applications
The Bently Nevada 330191-40-75-15-05 proximity probe is ideal for monitoring shaft vibration and position in critical rotating machinery such as steam turbines, compressors, and pumps. Its 8 mm diameter provides thicker coil encapsulation and a more robust tip, reducing the risk of damage from physical abuse. The CableLoc design delivers 330 N pull strength, ensuring the cable remains securely attached even under high stress. This probe is suitable for use in hazardous areas with its CSA, ATEX, and IECEx approvals.
Installation and Setup Guidance
When installing the Bently Nevada 330191-40-75-15-05, ensure the thread engagement does not exceed 0.563 inches on a 3/8-24 UNF hole. Tighten the connector to a maximum torque of 0.565 N·m. The probe uses a Viton O-ring for sealing; note that probes are not pressure tested before shipment. For 1-meter total length systems, no extension cable is required. The unthreaded length is 4.0 inches, and the overall case length is 7.5 inches.
Maintenance and Reliability
This Bently Nevada 330191-40-75-15-05 probe features a patented TipLoc molding method that creates a robust bond between probe tip and body, reducing maintenance needs. The CableLoc design prevents cable pull-out. Optional FluidLoc cable prevents oil wicking, extending service life. Regular inspection of the cable and connector is recommended. With appropriate care, the probe delivers reliable performance in demanding environments.
Selection Guide and Purchasing Advice
Before purchasing the Bently Nevada 330191-40-75-15-05, verify that the thread size (3/8-24 UNF), unthreaded length (4.0 in), overall case length (7.5 in), total length (1.5 m / 4.9 ft), and agency approval option (05 = CSA, ATEX, IECEx) meet your system requirements. PLC Source PRO supplies this item new in original factory packing with a 12-month warranty, ensuring you receive a genuine, reliable component for your automation needs.
