The Bently Nevada 330902-36-89-05-01-00 is a high-precision proximity probe belonging to the 3300 NSv (Narrow Side view) series. This transducer is specifically designed for industrial applications where installation space is restricted or where target diameters are smaller than standard 8 mm probes can accommodate. It is primarily utilized for radial vibration, axial thrust position, and speed measurements on small-bore rotating machinery, such as centrifugal compressors, aero-derivative gas turbines, and specialized industrial pumps. The 3300 NSv system is engineered to provide a linear voltage output over a defined range when paired with a matching Proximitor Sensor, ensuring reliable machinery protection and diagnostic data for Plant Asset Management.
The model string 330902-36-89-05-01-00 defines the physical dimensions and electrical configuration of the probe:
330902: 3300 NSv Proximity Probe, 3/8-24 UNF thread, without armor.

89: Overall Case Length Option of 8.9 inches.
05: Total Length Option of 0.5 meter (1.67 feet).
01: Connector Option specifying a miniature coaxial ClickLoc connector with an integrated connector protector and standard cable.
00: Agency Approval Option; no specific hazardous area certifications required for this unit.

| Shipping Weight | 1.5 kg |
What are the primary applications for the 3300 NSv series?
The NSv series is optimized for targets as small as 0.25 inches (6.35 mm) in diameter. It is used when a standard 8 mm probe would experience "side-view" interference from surrounding metal or when the shaft diameter is too small for a standard sensor to maintain linearity.
Can I use this 0.5-meter probe with a 9.0-meter extension cable?
No. The total system length (probe plus extension cable) must match the Proximitor Sensor's calibration. For a 0.5-meter probe, you would typically use a 4.5-meter extension cable to achieve a 5.0-meter total system length, or a 6.5-meter cable for a 7.0-meter system.
How does the connector protector benefit the installation?
The 01 connector option includes a protector that prevents the miniature coaxial ClickLoc connector from becoming contaminated by oil, moisture, or dust. It also provides mechanical strain relief to prevent the connector from vibrating loose during machine operation.
The 330902-36-89-05-01-00 features a 3/8-24 UNF thread. During installation, ensure the mounting hole is tapped cleanly and free of debris. Use a lubricant that is compatible with the machine's environment. The 3.6-inch unthreaded portion is designed to pass through the machine housing or bracket without thread engagement, allowing for easier adjustment of the probe gap.
Proper transducer performance depends on the mechanical "Gap" between the probe tip and the target. Connect the probe to the Proximitor and monitor the DC voltage. For the 3300 NSv system, the probe should be adjusted until the Proximitor outputs the specific center-gap voltage (typically -10.0 VDC). Secure the locknut once the gap is established to prevent the probe from backing out due to thermal expansion or vibration.
The standard cable on the 330902-36-89-05-01-00 is FEP insulated but does not include stainless steel armor. To prevent mechanical damage, route the probe cable through rigid or flexible conduit immediately upon exiting the machine housing. Observe the minimum bend radius of 25.4 mm (1.0 inch) to prevent internal dielectric damage which can cause signal noise or "spiking" in vibration data.
