Product Overview

The 330901-00-09-05-02-00 is a specialized transducer from the Bently Nevada 3300 NSv (Narrow Side View) series, engineered for high-accuracy displacement monitoring in machinery where space is severely restricted. This eddy current sensor is specifically designed to work in environments with narrow counterbores or where the probe must be mounted in close proximity to adjacent metal surfaces that would interfere with standard 8mm probes. By utilizing a smaller tip and a focused magnetic field, this probe provides precise radial vibration and axial position data, ensuring compliance with API 670 standards for machinery protection and reliability.

Primary Hardware Attributes and Physical Dimensions

The technical construction of this probe focuses on chemical resistance and mechanical stability within tight tolerances.

• Housing Dimensions: 1.8 cm x 1.6 cm x 123 cm (shipping/sleeve reference)

• Tip Material: High-performance Polyphenylene Sulfide (PPS)

• Connection Type: Miniature coaxial ClickLoc connector for rapid, secure coupling

• Mounting Threads: 1/4-28 UNF interface

• Signal Standards: Designed for seamless integration with 3300 NSv Proximitor Sensors

Core Industrial Deployment Scenarios

This proximity probe is the preferred choice for rotating equipment where the target area is limited or the installation port is narrow.

• Small Shaft Monitoring: Ideal for measuring vibration on shafts with diameters under 51 mm (2 inches) where standard sensors lose linearity.

• Tight Counterbores: Specifically used in machinery where the probe must be recessed into a hole with very little side clearance.

• Fluid-Filmed Bearings: Monitoring the oil film thickness and shaft stability in high-speed auxiliary turbines and pumps.

• Thrust Measurement: Tracking axial movement on small collars or shaft shoulders in centrifugal compressors.

• TSI Integration: Serving as a front-end sensor for Turbine Supervisory Instrumentation to provide early warning of mechanical wear.

FAQ

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

The NSv or "Narrow Side View" probes are designed with a tighter magnetic field pattern, allowing them to provide accurate readings in narrow spaces where a standard probe would suffer from "side-view" interference from surrounding metal.

Q: Is the 0.5-meter cable length sufficient for all installations?

This 0.5-meter length is typically used as the "lead-out" portion that connects to an extension cable, which then leads to the Proximitor sensor located in a nearby junction box.

Q: Can the PPS tip withstand exposure to industrial lubricants?

Yes, the Polyphenylene Sulfide (PPS) tip is highly resistant to moisture, synthetic oils, and the chemical additives commonly found in industrial lubrication systems.

Q: What is the benefit of the ClickLoc connector used on this model?

The ClickLoc connector is a miniature coaxial design that prevents accidental disconnection due to vibration while remaining small enough to be pulled through narrow conduits during installation.

Q: Does this probe require a specific type of Proximitor?

Yes, it must be paired with a 3300 NSv Proximitor. Using it with a standard 3300 XL or 8mm Proximitor will result in incorrect calibration and inaccurate vibration data.
