Description：

The Bently Nevada 330901-05-65-05-11-05 is a 3300 XL NSv Reverse Mount Probe engineered for machinery protection and condition monitoring applications where installation space is limited or the monitored shaft has a small target area. As part of the 3300 XL NSv Transducer System, it operates with a compatible NSv extension cable and Proximitor sensor to deliver accurate, non-contact displacement measurements in demanding industrial environments.

The 330901-05-65-05-11-05 features an average scale factor of 7.87 V/mm (200 mV/mil), providing the standard output commonly used by eddy current proximity transducer systems. This output ensures reliable compatibility with Bently Nevada monitoring systems while delivering stable and repeatable measurement performance for critical machinery protection applications.

Compared with standard 3300 XL 5 mm and 8 mm transducer systems, the NSv probe offers enhanced side-view capability and improved performance when monitoring smaller targets. Although its 1.5 mm (60 mils) linear measurement range is shorter than that of standard 3300 XL probes, it exceeds the linear range available from the earlier 3000-series 190 Transducer System, offering improved measurement accuracy and greater application flexibility.
