The 330905-00-18-05-02-CN is a 3300 NSv series reverse mount proximity probe. This series is specifically engineered for monitoring applications in narrow spaces or on small-diameter shafts. The reverse mount design allows the probe to be threaded into the housing from the rear.
Phase reference (Keyphasor signals)
Axial (thrust) position measurements
Tachometer and zero speed measurements
The 3300 XL NSv Proximity Transducer system is intended for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements. The primary uses for the 3300 XL NSv Transducer System are for areas where counter bore, sideview, or rearview restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems. It is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in). The 3300 XL NSv Transducer System design allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 XL NSv system may use the existing probe, extension cable, and monitoring system with 3300 XL NSv Proximitor Sensor.

Textile Industry
Measuring radial runout of rotors with extremely small shaft diameters.
When using the 330905-00-18-05-02-CN probe, it is critical to pair it with a dedicated 3300 NSv Proximitor. Mixing it with standard 8mm Proximitors will cause severe linear distortion. Due to its reverse-mount design, ensure secure threading with the probe housing and calibrate the gap voltage (typically -10Vdc) to the center of the 60-mil linear range. Furthermore, as it carries the -CN certification, strict adherence to Chinese explosion-proof standards is mandatory in hazardous areas. Regularly inspect the ClickLoc connectors to prevent signal drift caused by oil ingress or poor contact.
It is a 3300 XL series 8mm Reverse Mount Proximity Probe with Chinese Agency Approvals, manufactured by Bently Nevada.
What does NSv stand for in 330905-00-18-05-02-CN?
It stands for "Narrow Space," designed for small-diameter shafts or applications with restricted installation space.
What is the primary use of 330905-00-18-05-02-CN?
It is used for non-contact measurement of radial vibration, axial position, or speed of small rotating machinery.
What is the sensitivity of 330905-00-18-05-02-CN?
Its standard sensitivity is 7.87 V/mm (200 mV/mil).
Why is 330905-00-18-05-02-CN preferred for small shafts?
Because NSv technology effectively reduces non-linear errors caused by the curvature of small-diameter shafts.
