Product Overview
The Bently Nevada 330105-02-12-15-02-05 is a reverse-mount, non-contact proximity probe from the 3300 XL 8 mm series. Designed for precise static and dynamic measurements (such as shaft position and vibration), it is widely used in fluid-film bearing machinery. It offers superior robustness, API 670 compliance, and complete system interchangeability.
Applications
-
Shaft vibration and position monitoring
-
Keyphasor and speed measurements
-
Overspeed protection (when paired with proper configurations)
-
Monitoring of rotating equipment in turbines, compressors, and pumps
-
Suitable for confined mounting due to reverse-mount design
Advantages
-
Reverse mount for limited space installations
-
API 670 compliant performance
-
Fully interchangeable components (probe, cable, Proximitor)
-
Improved RFI/EMI immunity
-
Patented TipLoc and CableLoc designs ensure durability
-
FluidLoc cable option available for oil ingress protection
-
ClickLoc connectors ensure secure, tool-free connection
