Bently Nevada 3300 XL Proximitor Sensor System Replacement for 330103-00-06-10-02-00
The Bently Nevada 330103-00-06-10-02-00 is a high-precision 3300 XL Proximitor Sensor designed for critical vibration and position monitoring. This sensor conditions eddy current signals into a linear voltage output, supporting predictive maintenance and Turbine Supervisory Instrumentation (TSI) for high-speed rotating assets.
Product Description
Precision Signal Conditioning for Machinery Protection
The Bently Nevada 330103-00-06-10-02-00 represents a specialized configuration of the 3300 XL Proximitor Sensor, a cornerstone of modern Turbine Supervisory Instrumentation (TSI). Because accurate signal processing is vital for machinery protection, this sensor performs two critical tasks: it provides the high-frequency excitation for the proximity probe and subsequently conditions the returning signal. By converting the complex eddy current fluctuations into a stable, linear DC voltage, the Proximitor allows monitoring systems to measure exact shaft vibration and position. Consequently, this device enables industrial plants to transition from reactive repairs to a data-driven predictive maintenance model.
Advanced Internal Circuitry and Calibration-Free Design
To ensure maximum signal integrity, the sensor utilizes advanced internal circuitry that compensates for cable length and environmental temperature shifts. When a probe detects a change in the gap between its tip and the target shaft, the Proximitor generates an output voltage that directly corresponds to that displacement. Furthermore, this 3300 XL model features a sophisticated design that eliminates the need for external calibration when using matched 8mm probes and extension cables. Because the housing uses an integral mounting plate or DIN rail options, it simplifies installation within local junction boxes or centralized control cabinets.
Robust Performance in Harsh Industrial Environments
The 330103-00-06-10-02-00 also maintains a high signal-to-noise ratio, which is essential for detecting the subtle harmonic vibrations that precede bearing failure. Moreover, its robust construction ensures reliable operation near heavy industrial equipment where electromagnetic interference is common. By delivering a constant 7.87 V/mm (200 mV/mil) scale factor, the sensor provides the precise resolution required for monitoring high-speed compressors, steam turbines, and large-scale pumps. Therefore, integrating this Proximitor into your facility’s monitoring framework significantly enhances equipment lifespan and prevents catastrophic mechanical failures.

330703-00-100-10-11-CN | Bently Nevada | 3300 XL 11 mm Proximity Probes
Technical Overview
The Bently Nevada 330703-00-100-10-11-CN is an 11 mm eddy current proximity probe designed for non-contact displacement and vibration measurement on rotating machinery. It functions as a core component of the 3300 XL 11 mm Transducer System, which also includes a matched extension cable and a 3300 XL 11 mm Proximitor Sensor. The system operates on the eddy current principle, where the Proximitor Sensor emits a high-frequency radio frequency (RF) signal through the probe and extension cable. This signal radiates from the probe tip, creating an electromagnetic field. When a conductive target, such as a machine shaft, enters this field, eddy currents are induced on its surface. These currents create a secondary magnetic field that opposes the primary field, causing a measurable change in the RF signal's impedance. The Proximitor Sensor demodulates this signal to produce a DC voltage directly proportional to the gap between the probe tip and the target surface. This analog voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500 series, for real-time analysis of radial vibration, axial position, and shaft speed. The 330703-00-100-10-11-CN features a robust stainless steel case and a chemically resistant Polyphenylene Sulfide (PPS) tip, ensuring reliability in harsh industrial environments.

Operational Capabilities
The 330703-00-100-10-11-CN proximity probe is engineered for high reliability in demanding industrial applications, particularly within Oil & Gas and Power Generation sectors. Its 11 mm tip provides a larger linear measurement range and is well-suited for monitoring large shaft diameters or applications requiring a greater standoff distance. The probe's construction ensures operational integrity across a wide temperature range, with the probe tip rated for -51 °C to +177 °C (-60 °F to +351 °F). The 3300 XL system design provides enhanced immunity to radio frequency interference (RFI/EMI), minimizing the risk of signal corruption from nearby motors, generators, or radio sources. The gold-plated ClickLoc™ connector ensures a secure, corrosion-resistant connection that prevents intermittent signals caused by vibration. When installed and maintained according to manufacturer specifications, the system demonstrates high Mean Time Between Failures (MTBF) and is a critical component for machinery protection systems (MPS) and condition monitoring programs, compliant with standards such as API 670.

Technical FAQ
Q: What systems is the 330703-00-100-10-11-CN compatible with?
A: The 330703-00-100-10-11-CN probe must be used as part of a complete Bently Nevada 3300 XL 11 mm Transducer System. This requires a matching 3300 XL 11 mm Proximitor Sensor (e.g., part number 330780) and a 3300 XL 11 mm extension cable. It is not interchangeable with components from 5 mm or 8 mm transducer systems, as the scale factor and linear range are different. The complete transducer system provides a voltage output compatible with Bently Nevada monitoring systems, including the 3500 and 3300 series, as well as third-party PLCs, DCS, and data acquisition systems designed to accept a 3-wire, -24 Vdc powered eddy current probe input.
Q: What are the installation requirements?
A: Proper installation is critical for accurate measurements. The probe must be mounted perpendicular to the observed shaft surface using a rigid bracket. The target area on the shaft must be smooth (typically 0.4 to 0.8 µm / 16 to 32 µin Ra), free of chrome or other non-conductive plating, and clear of any residual magnetism or electrical runout. The probe must be gapped correctly by adjusting its distance to the shaft until the Proximitor Sensor output voltage is at the center of the linear range, typically -10.0 Vdc. The probe case locknut should be torqued to the specified value to prevent loosening. The integral cable and any extension cable should be secured to avoid strain on the connectors and routed away from high-voltage power cables to minimize interference.
