Product Brief: Bently Nevada 330101-00-60-10-02-00 (3300 XL 8mm Right-Angle Probe System)
The 330101-00-60-10-02-00 is a complete 3300 XL 8mm Proximity Probe System from Bently Nevada (GE Measurement & Control). This specific configuration features a right-angle (90°) probe tip design, which is used in applications where straight probe access is limited due to space constraints or interference with other machine components. The system includes the probe tip, integral cable, and Proximitor (driver/oscillator/demodulator) as a factory-matched set.
This system is used for non-contact eddy current measurement of shaft relative vibration, axial (thrust) position, eccentricity, and differential expansion in rotating machinery, particularly in tight bearing housings or retrofit applications.

Application Scenarios (use cases)
| Application Area | Description |
|---|---|
| Steam Turbine (Tight Bearing Housing) | Right-angle probe allows mounting when radial clearance to bearing housing cover is limited (e.g., older turbine retrofits). |
| Gas Turbine Compressor Section | Access through existing ports without removing adjacent piping or instrumentation – short 60mm case reduces interference. |
| Centrifugal Compressor (Retrofit) | Replacing older 7200 or 3300 standard probes with right-angle version to avoid oil drain ports or bolt bosses. |
| Generator End Windings (Limited Access) | Right-angle probe fits between stator bars or cooling ducts where straight probe cannot align. |
| Hydro Turbine Guide Bearing | Short case + right-angle cable exit allows mounting inside oil bath thrust bearing housings with limited clearance. |
| Turboexpander (LNG / Cryogenic) | Compact machinery skids often require right-angle probes for shaft monitoring at inlet/outlet ends. |
| Large Gearbox Bearing Monitoring | Used on high-speed pinion bearing housings where straight probe would interfere with gear mesh area. |
| Test Stand / Bearing Development Rig | Right-angle design simplifies installation in experimental rigs with complex housing geometries. |
Notes
This is a right-angle probe – the integral cable exits at 90° from the probe tip axis. This is not a standard straight probe.
60 mm case length is shorter than standard (typically 80 mm), reducing the probe's protrusion into the housing.
Complete system – includes the Proximitor (driver). No additional components are needed to connect to a compatible monitor (e.g., 3500/40, 3500/42, 1900/65A).
The 10 meter cable length is integral and cannot be extended without signal degradation. For longer runs, use extension cable 330190-X0-00 (up to 305 m total).
The BNC connector (suffix 02) connects directly to standard 3300 XL Proximitor input. For terminal block connections, order suffix 03.
Right-angle probes have the same electrical performance as straight probes – no sensitivity or linear range derating.
Not intrinsically safe by itself. For hazardous area (Class I, Div 1/Zone 1) installations, use Bently Nevada IS barrier (e.g., 3300 XL IS system) or 3500/42M monitor with internal barriers.
Target material calibration is for AISI 4140 steel. For other materials (e.g., stainless steel, titanium, Inconel), consult Bently Nevada for correction factors or custom calibration.
Probe tip gap setting – static gap should be set at mid-range (approximately -10 VDC output) to maximize dynamic measurement range.
