The primary uses for the 3300 XL NSv Transducer System arefor areas where counter bore, sideview, or rearviewrestrictions limit the use of standard Bently Nevada 3300 and3300 XL 5 and 8 mm Transducer Systems. It is also ideal forsmall target applications, such as measuring radial vibrationon shafts smaller than 51 mm (2 in) or axial position on flattargets smaller than 15 mm (0.6 in). It is primarily used in thefollowing applications on fluid-filmed bearing machineswhere a small shaft or reduced side-view is present:

Radial vibration and radial position measurements 

Axial (thrust) position measurements*

Tachometer and zero speed measurements

Phase reference (Keyphasor signals)

Frequently Asked Questions

Q1: What is the Bently Nevada 330903-00-09-05-02-CN?

A1: It is a proximity probe used for non-contact measurement of shaft vibration and displacement in rotating machinery condition monitoring systems.

Q2: What is the 330903-00-09-05-02-CN supply voltage requirement?

A2: The 330903-00-09-05-02-CN probe operates on a nominal supply voltage of −24 V DC.

Product Applications

Oil & Gas: Used in centrifugal air compressors, refrigeration compressors, and process gas compressors. These equipment have compact internal spaces. The NSv probe, with its "narrow side view" feature, can effectively reduce measurement interference when the shaft diameter is small (such as less than 30mm) or there are surrounding blind holes.

Power Generation: Monitors the radial vibration and axial displacement of steam turbines, water turbines, and associated rotating auxiliary equipment to ensure asset protection and condition monitoring, preventing significant losses due to bearing wear or unplanned shutdowns.

Heavy Industry Manufacturing: In heavy rotating machinery in industries such as petrochemicals and smelting, it is used to detect early signs of faults in real time and optimize equipment operation efficiency.
