Key Features:
Reverse Mount Design: Optimized for installations with limited space, allowing the probe cable to exit away from the measurement target .
High-Temperature Capability: Operates reliably in extreme thermal environments up to 177°C, making it suitable for turbine and compressor applications .
Interchangeable Components: All 3300 XL 8 mm system components are backward compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm components, eliminating the need for matching parts .
Precision Measurement: Offers a sensitivity of 200 mV/mil (7.87 V/mm) and a linear range of 2 mm, ensuring accurate detection of shaft vibration and position changes .
Hazardous Area Approvals: Certified with CSA, ATEX, and IECEx for use in potentially explosive environments .
Within the Bently Nevada 3300 XL 8 mm probe family, the primary distinction lies in the mounting thread size and the probe's mechanical dimensions. The 330105 series uses a 3/8-24 UNF thread. For comparison, the 330101 features a M8 x 1 metric thread, and the 330103 features an M10 x 1 metric thread .
| Model No. | Thread Type | Application / Notes |
|---|---|---|
| 330105-02-12-05-12-05 | 3/8-24 UNF | Target model; reverse mount, 0.5m length, ClickLoc connector, hazardous area approvals . |

| 330105-02-12-90-12-05 | 3/8-24 UNF | Same as target model but with a 9.0 meter total length . |
| 330101-02-12-05-12-05 | M8 x 1 | Metric thread for installations requiring an M8 x 1 thread . |
| 330103-02-12-05-12-05 | M10 x 1 | Metric thread for installations requiring an M10 x 1 thread . |
Q1: What does the suffix "02-12-05-12-05" represent?
The suffix specifies the probe's mechanical and electrical options:
02: 0.2 inch unthreaded length .
12: 1.2 inch case length .
05: 0.5 meter total probe length .
12: Miniature ClickLoc connector with FluidLoc cable .
05: CSA, ATEX, IECEx hazardous area approvals .
Q2: What is the primary application of this probe?
It is used for non-contact measurement of shaft relative vibration, axial position, and speed on fluid-film bearing machines, including turbines, compressors, and fans .
Q3: What is the recommended initial gap voltage for installation?
The recommended initial gap voltage for the 3300 XL 8 mm system is -10 VDC ±1 VDC . This ensures the probe operates within its linear measurement range.
Q4: Can I mix this probe with a non-XL 3300 series extension cable?
Yes, all 3300 XL 8 mm transducer system components are backward-compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm components . However, for optimal performance and to maintain API 670 compliance, using the full 3300 XL system is recommended.
