Product Details
The 330103-00-09-20-02-00 is an 8 mm eddy-current proximity probe from the Bently Nevada 3300 XL series designed for non-contact vibration and relative position measurement in rotating machinery. This model features an M10 x 1 metric thread profile without outer armor, a 0 mm unthreaded length, a 90 mm overall case length, and a 2.0-meter total cable length. It is equipped with a miniature coaxial ClickLoc connector and operates without requiring specialized hazardous-area agency approvals.
Mechanical Configuration and Suffix Breakdown
The base model 330103 designates the standard unarmored 3300 XL 8 mm proximity probe configuration. The initial -00 option specifies an unthreaded length of 0 mm, while the -09 option establishes a 90 mm overall case length for installation depth. The -20 code defines a total cable length of 2.0 meters (6.6 feet). The -02 option indicates a standard cable terminated with a miniature coaxial ClickLoc connector, and the final -00 code denotes standard agency approval without hazardous-area certification.
Signal Characteristics and System Integration
Operating on eddy-current principles, the probe senses the gap distance between its polyphenylene sulfide (PPS) tip and a conductive machine shaft, supporting standard -10 VDC gap voltage calibration. It yields a linear measurement range between 0.25 mm and 2.3 mm with a sensitivity of approximately 7.87 V/mm (200 mV/mil). The coaxial construction suppresses cross-talk and maintains stable rotor-dynamic signal transmission through industrial wiring pathways.
Field Installation Guidelines
- Maintain straight routing of the 2.0-meter cable to preserve coaxial impedance.
- Align the probe tip perpendicular to the rotor surface for accurate displacement measurement.
- Avoid tight bends near the ClickLoc connector to maintain coaxial geometry.
- Ground shielding at the driver end only to prevent ground-loop interference.
- Verify gap voltage during commissioning to confirm correct mechanical positioning.

Frequently Asked Questions
Q: Must the probe be paired with a specific extension cable length?
A: Yes. Eddy-current probes require exact cable length matching to maintain correct -10 VDC gap voltage calibration.
Q: Can the probe be installed near high-current conductors?
A: It is not recommended. Electromagnetic fields may distort the sensing field and affect measurement linearity.
Q: Is the probe suitable for high-temperature bearing housings?
A: The operating temperature range of -52 deg C to +177 deg C supports typical fluid-film bearing environments.

Tech & Buying Guide
Designing Robust SCADA Systems for Electrical Substation Automation
Electrical substation automation requires rigorous engineering standards to guarantee uninterrupted power distribution and grid stability. Therefore, control engineers must design supervisory control and data acquisition (SCADA) architectures with absolute precision. In my 15 years of commissioning power protection and substation automation systems, I have witnessed how meticulous SCADA design prevents catastrophic grid failures. Below, I outline the critical engineering practices required to build reliable substation SCADA solutions.
Demystifying Earthing, Grounding, and Bonding in Industrial Process Plants
Industrial automation networks, power distribution systems, and complex control loops rely heavily on proper grounding to maintain operational integrity. Therefore, control engineers and electrical specialists must thoroughly understand the distinctions between earthing, grounding, and bonding. In my 15 years of commissioning distributed control systems (DCS) and factory automation architectures, I have encountered numerous mysterious equipment failures caused by improper grounding practices. Below, I clarify these essential concepts and outline the industry standards governing industrial electrical safety.
Empowering Predictive Maintenance in PLC and SCADA Systems Through Maintenance Management
Industrial automation networks constantly generate vast streams of diagnostic data before major equipment failures occur. Therefore, integrating control systems with maintenance management platforms is essential for maximizing plant uptime. In my 15 years of commissioning programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) networks, I have witnessed how raw alarms sit unnoticed in controller buffers. Bridging the gap between automation software and computerized maintenance management systems (CMMS) transforms early warning signals into actionable work orders. Below, I examine how this integration drives predictive maintenance across modern industrial facilities.
