Product Overview

The Bently Nevada 330910-03-16-10-02-00 is a specialized 3300 NSv (Narrow Side view) proximity probe engineered for applications where standard sensor envelopes are too large. This high-precision eddy current sensor is designed to provide non-contacting displacement and vibration data in restricted mounting spaces. It is particularly effective for observing small-diameter shafts or targets where "side-view" interference from surrounding metal must be minimized. Featuring an armored cable for enhanced mechanical protection and a miniature ClickLoc coaxial connector, this probe ensures stable signal transmission for critical machinery protection systems.

Specialized Engineering Deployments

Small Shaft Radial Vibration

The 3300 NSv series is the primary choice for monitoring shafts with diameters smaller than 51 mm (2 inches). Standard 8mm probes often suffer from "cross-talk" or distorted signals on small curvatures; the 330910-03-16-10-02-00 is specifically calibrated to ignore side-view interference, ensuring accurate vibration readings.

Centrifugal Compressor Protection

In high-speed compressors where internal clearances are extremely tight, this probe monitors radial position and shaft stability. Its armored cable prevents damage from high-velocity oil flow and mechanical debris within the bearing housing.

Thrust Position in Restricted Housings

Used to monitor axial movement in small turbines or auxiliary pumps. The M10x1 reverse-mount or narrow-view configuration allows the probe to be positioned in recessed areas where a standard probe would be physically impossible to install.

Cryogenic and High-Heat Environments

With a wide operational temperature envelope, this probe remains stable in extreme industrial climates, making it suitable for both cold-service pumps and hot-service steam turbine supervisory instrumentation (TSI).

FAQ

Q: What makes the "NSv" version different from a standard 3300 XL probe?

A: NSv stands for "Narrow Side view." These probes are designed for much smaller targets and narrower mounting gaps. They use a different Proximitor and are specifically intended for shafts smaller than 2 inches in diameter where a standard probe would provide inaccurate data.

Q: Is the 330910-03-16-10-02-00 interchangeable with standard 8mm extension cables?

A: No. The 3300 NSv series has specific electrical characteristics. You must use it with a dedicated 3300 NSv extension cable and a 3300 NSv Proximitor to ensure the correct scale factor and linear range.

Q: How does the stainless steel armor benefit the installation?

A: The armor provides superior crush resistance and protects the fluoropolymer-insulated lead from being cut or abraded during installation or by the movement of parts within the machine casing.

Q: Can this probe be used as a tachometer sensor?

A: Yes. Due to its high frequency response (up to 10 kHz), it is excellent for sensing gear teeth or shaft notches to provide RPM data and phase reference signals (Keyphasor) to a 3500 series monitoring rack.

Q: Does this model carry hazardous area certifications?

A: Yes, as part of the Bently Nevada 3300 system, these probes are designed to meet international standards such as ATEX and IECEx for use in intrinsically safe environments when paired with the correct safety barriers.
