Product Overview

The 330905-02-10-05-02-CN is a specialized 3300 NSv (Narrow Sideview) proximity probe engineered by Bently Nevada for high-precision monitoring in restricted spaces. This eddy-current sensor is specifically designed for applications where standard 5 mm or 8 mm proximity systems encounter side-view or rear-view interference. By utilizing a compact tip design, the 330905-02-10-05-02-CN can accurately measure shaft vibration and position on targets that are physically smaller than those required by standard transducers. This model features a rugged armored cable and metric M10x1 threading, ensuring survivability in harsh industrial environments while maintaining the high-fidelity signal required for critical machinery protection.

Essential Hardware Configuration and Parameters

Industrial Utility and Targeted Applications

The 3300 NSv system is the industry standard for monitoring small-diameter shafts and confined bearing housings. The 330905-02-10-05-02-CN is particularly effective for radial vibration measurements on shafts smaller than 51 mm (2 inches) or axial thrust measurements on targets smaller than 15 mm (0.6 inches). It is commonly deployed on high-speed centrifugal compressors, small pumps, and specialized turbine auxiliary equipment. Because the NSv probe tip has a smaller electromagnetic "footprint," it is less sensitive to "cross-talk" from adjacent metal surfaces, allowing it to be installed in tight counterbores where standard 8 mm probes would suffer from signal saturation or inaccurate gapping.

FAQ

Q: What makes the 3300 NSv different from the standard 3300 XL series?

A: The NSv (Narrow Sideview) is designed for small targets and tight spaces. Standard probes require a larger target area to form a stable magnetic field; the NSv probe can provide accurate data on much smaller shaft diameters and targets with limited side-clearance.

Q: Is the 330905-02-10-05-02-CN compatible with standard 3300 XL extension cables?

A: No, the 3300 NSv probes require specific NSv extension cables and Proximitor sensors. The electrical characteristics are optimized for the smaller tip diameter and are not interchangeable with standard 3300 XL 8 mm system components.

Q: Does the "CN" suffix affect the technical performance of the probe?

A: The CN suffix typically denotes regional certification or compliance markers for the Chinese market. The core technical specifications, such as frequency response and linearity, remain identical to the global 330905 series.

Q: What is the benefit of the armored cable on this model?

A: The stainless steel armor prevents the coaxial cable from being pinched, cut, or crushed during installation or operation. This is especially vital in small machinery where cables must be routed through sharp-edged conduits or tight internal compartments.

Q: Can this probe be used for speed sensing or Keyphasor applications?

A: Yes, the 330905-02-10-05-02-CN is highly effective as a Keyphasor or tachometer sensor. Its ability to focus on a small target makes it excellent for detecting small notches or keyways on high-speed shafts.
