Bently Nevada 330905-00-25-05-12-CN 3300 NSv Proximity Probe

Frequently asked questions
Q:Which transducer system is compatible with the 330905-00-25-05-12-CN?
A:This probe is designed to operate with the 3300 XL NSv Proximitor Sensor and the matching 3300 NSv extension cable to form a complete measurement system.

Q:What are the configuration details of this model?
A:Model 330905-00-25-05-12-CN includes 0 mm unthreaded length, 2.5 in case length, 0.5 m total length, Miniature ClickLoc connector with FluidLoc cable, and the CN approval option.

Q:Why choose the NSv probe instead of a standard 5 mm or 8 mm probe?
A:The NSv design is intended for installations with counterbore, side-view, rear-view, or other mechanical restrictions where standard proximity probe systems cannot be easily installed.

Description

The Bently Nevada 330905-00-25-05-12-CN is a 3300 NSv proximity probe designed for use as part of the 3300 XL NSv Proximity Transducer System. This configuration features an M10 × 1 threaded probe body without stainless-steel armor, a 2.5-inch case length, a 5-meter total probe cable, a Miniature ClickLoc connector with standard cable and FluidLoc cable option, and multiple international approvals (CN option). It is intended for machinery where installation space is limited and where conventional 5 mm or 8 mm proximity transducer systems cannot be easily applied. The probe works with the matching 3300 XL NSv Proximitor Sensor and extension cable to provide stable, non-contact measurement of shaft vibration and position. It is commonly used on centrifugal air compressors, refrigeration compressors, process gas compressors, and other rotating equipment that require reliable monitoring in confined mounting locations. The NSv system is also suitable for small shaft diameters and restricted side-view, rear-view, or counterbore installations while maintaining compatibility with the standard 7.87 V/mm (200 mV/mil) output used by Bently Nevada eddy-current transducer systems.
