The 330103-00-10-10-02-CN is a 3300 XL series 8mm eddy current proximity probe manufactured by Bentley Nevada in the United States. It is mainly used for non-contact, high-precision vibration and displacement monitoring of large rotating machinery.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable with other non XL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Thermal and Gas Power Generation Industry
Installed on high-capacity steam turbine generators, gas turbines, and large feedwater pumps to perform non-contact measurement of axial displacement (thrust) and radial shaft vibration, preventing rotor-to-stator friction.
Oil and Gas Extraction and Transportation
Used for monitoring dynamic bearing wobble and machine Keyphasor (speed) on large natural gas centrifugal compressors, reciprocating compressors, and crude oil export pumps along long-distance pipelines.
Hydroelectric Power
Installed at the water guide bearings and thrust runners of large hydro-generator units to measure large-amplitude, low-frequency shaft swing.
Nuclear Power Industry
Used in the conventional island of nuclear power plants for safety monitoring of shaft thermal expansion and dynamic vibration on main turbine units, main feedwater pumps, and Main Coolant Pump (MCP) drive-end motors.
Paper and Pulping Industry
Used for non-contact displacement analysis of paper machine dryer drive shafts, large pulping pumps, and high-speed rewinder main drive bearings to prevent paper breaks caused by excessive vibration.
When using the 330103-00-10-10-02-CN, ensure it operates strictly within the rated temperature range of -51 °C to +177 °C. Never pull, cut, or splice its integrated 1.0-meter armored cable, and maintain a bend radius of ≥ 25.4 mm during routing. During installation, always monitor the gap voltage via the Proximitor (typically around -10 Vdc) to ensure the tip is centered within its 2.0 mm linear sensing range. Lastly, always install a connector protector after mating to prevent degradation from bearing housing oil mist and moisture.
What is the operating principle of 330103-00-10-10-02-CN?
It operates on the Eddy Current principle.
How is 330103-00-10-10-02-CN used in industry?
It is typically reverse-mounted and secured onto the bearing housings of large rotating machinery (such as heavy-duty steam turbines, compressors, and fans) using specialized brackets.
What is the purpose of the 02 (Armored Cable) option in this model?
The 02 option designates an integrated Stainless Steel Armor sleeve. It effectively protects the internal coaxial cable from mechanical abrasion, sharp cutting edges, or accidental crushing in harsh petrochemical and power plant environments, significantly improving cable durability.
What happens if the cable is bent due to space constraints when installing 330103-00-10-10-02-CN?
The bend radius limit must be strictly followed. The minimum bend radius for the armored cable is 25.4 mm (1.0 inch). Over-bending will damage the internal coaxial structure and alter capacitance properties, leading to severe measurement errors.
