Description

The 330901-00-90-10-02-05 is a specialized, high-performance transducer within the 3300 NSv Proximity Probes series by Bently Nevada. This 3300 NSv Proximity Probe is specifically engineered for critical machinery applications where "Narrow Sideview" (NSv) capabilities are essential. Unlike standard sensors, the 330901-00-90-10-02-05 is designed to operate with high precision in confined geometries, such as tight counterbores or restricted internal machine housings, where side-wall interference would typically degrade the signal of a standard 8mm probe. As a cornerstone of the 3300 NSv Proximity Probes lineage, this model features a 90 mm overall case length and a 0-inch unthreaded length, providing a robust and streamlined form factor for flush-mount installations.

The technical core of the 330901-00-90-10-02-05 involves a sophisticated eddy current principle that delivers a linear voltage signal proportional to the gap between the probe tip and a conductive target. In the 3300 NSv Proximity Probes ecosystem, this probe is optimized for small-diameter shafts (less than 51 mm or 2 inches), where it maintains exceptional linearity across a 1.5 mm (60 mils) range. This makes the 330901-00-90-10-02-05 an ideal 3300 NSv Proximity Probe for high-speed turbo-expanders, small centrifugal compressors, and refrigeration units.

Applications

The 330901-00-90-10-02-05 is primarily utilized for radial vibration and axial position monitoring in small-bore machinery. Due to its "Narrow Sideview" (NSv) design, it is the preferred choice for industrial refrigeration compressors and air centrifugal units where the mounting location is inside a narrow counterbore. These 3300 NSv Proximity Probes can be installed in tight structural pockets without the signal being distorted by the surrounding metal, providing accurate shaft motion data that standard probes cannot capture.

This probe is highly effective for monitoring high-speed shafts with small diameters (under 2 inches). In turbo-expanders and precision pumps, the shaft curvature often compromises the linearity of standard sensors. The 330901-00-90-10-02-05 overcomes this by concentrating the sensing field, allowing for precise gap measurement and vibration analysis. This ensures that even the smallest imbalances or bearing misalignments are detected early, safeguarding high-value rotating assets from catastrophic failure.

The 330901-00-90-10-02-05 serves as a critical phase reference and speed sensing tool (Keyphasor) in harsh thermal environments. With a 1.0-meter total length and a 1.0 mm recommended gap setting, it accurately triggers off small timing notches or keyways on a rotating shaft. Its wide temperature rating allows it to function near turbine exhausts or in cryogenic cooling systems, providing the synchronized data necessary for 1X vibration vectors and overspeed protection systems.

Specifications

Competitive Advantage

1. Superior Resistance to Side-View Interference

The 330901-00-90-10-02-05 features a specialized "Narrow Sideview" geometry that is a hallmark of the 3300 NSv Proximity Probes. This allows the probe to be recessed or flush-mounted in metal housings that would normally cause signal "cross-talk" or saturation in larger probes. This capability drastically simplifies machine design and sensor retrofitting in congested mechanical environments.

2. Enhanced Mechanical Protection and Connectivity

This model is equipped with the Miniature coaxial ClickLoc connector along with a specialized connector protector. This advantage prevents the sensor from vibrating loose in high-G environments and protects the electrical interface from moisture, oil, and dust. This ensures a stable 45 Ω output resistance and maintains signal integrity over its 1.0-meter integrated cable, reducing maintenance intervention.

3. Precision Linearity on Small Targets

Unlike general-purpose 8mm sensors that struggle with target curvature, the 330901-00-90-10-02-05 is factory-tuned for high linearity on shafts smaller than 51 mm. This precision allows for more accurate vibration resolution, enabling maintenance teams to identify subtle changes in machine health that would be "averaged out" or missed by less specialized proximity sensors.
