Bently Nevada 330103-00-03-15-01-CN 8mm Proximity Transducer System – 3300 XL Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft displacement, catastrophic bearing failure, unplanned downtime, and in worst cases, irreversible damage to turbines, compressors, or pumps worth millions of dollars. In high-stakes industrial environments — power generation, oil & gas, petrochemical — the absence of a reliable proximity transducer is not a minor gap. It is a safety and operational crisis. The Bently Nevada 330103-00-03-15-01-CN is the precision instrument that stands between normal operation and disaster.
The 330103-00-03-15-01-CN is an 8 mm eddy-current proximity transducer within Bently Nevada’s industry-defining 3300 XL Series — the global benchmark for continuous machinery protection systems. Designed for radial shaft vibration, axial position, and differential expansion measurement, this transducer system is trusted in over 100 countries across power plants, LNG terminals, refineries, and rotating equipment OEM platforms. Its 3300 XL lineage ensures backward compatibility with existing Bently Nevada monitoring infrastructure while delivering the measurement accuracy demanded by API 670 machinery protection standards.

System Integration & Compatible Parts
The 330103-00-03-15-01-CN operates as part of a complete 3300 XL transducer system. Ensure compatibility with the following components:
- Proximitor® Sensor: 3300 XL series (e.g., 330180, 330181) — must be matched to the 8 mm probe system.
- Extension Cable: Included in this part number configuration (15 m); verify total cable length against your installation gap voltage requirements.
- Monitoring Modules: Compatible with 3500 Series Machinery Protection System racks (3500/40M, 3500/42M, 3500/45, 3500/46M).
- Target Material: AISI 4140 steel or equivalent; consult Bently Nevada calibration data for non-standard target materials.
- Mounting Hardware: Standard 3300 XL probe mounting brackets and lock nuts — verify thread specification (M10 x 1 mm standard).
