3300 XL 11mm Eddy Current Probe 330703-000-100-10-11-00 by Bently Nevada

Brief Product Description

This industrial eddy current sensor measures critical shaft displacement without making physical contact. It operates within the 3300 XL 11mm system to track large-scale vibration trends.

Product Description

The Bently Nevada 330703-000-100-10-11-00 represents a high-performance 11mm proximity probe from the trusted 3300 XL portfolio. Because this sensor utilizes a larger 11mm tip diameter, it provides an extended linear measurement range compared to conventional 8mm variants. This device delivers an accurate voltage output profile of 3.94 V/mm (100 mV/mil) when combined with a matching Proximitor sensor and extension cable.

Core Functional Applications

Turbine Supervisory Instrumentation (TSI) networks integrate this probe to handle demanding displacement tracking tasks. The expanded linear spectrum makes it ideal for machinery that undergoes large axial movements or thermal expansion.

• Axial thrust position monitoring on large-scale utility steam and gas turbines
• Ramp differential expansion tracking to evaluate casing and rotor thermal growth
• Radial vibration measurements for oversized shaft assemblies and fluid-film bearings
• Phase reference signaling via Keyphasor configuration for diagnostic timing data
• Rod position and rod drop monitoring in high-pressure reciprocating compressors

Technical Characteristics and Design Features

This proximity probe incorporates heavy-duty mechanical engineering to survive the punishing environments found inside industrial machine casings. The physical build features an M14 x 1.5 threaded body that simplifies rigid mounting during setup. Additionally, gold-plated ClickLoc coaxial connectors seal the electrical connection against oil, moisture, and chemical contamination.

• Extended measurement range allows tracking across wider gap variances
• Seamless integration into existing 3300 XL 11mm system configurations
• Robust tip chemistry protects the internal coil from harsh automated processes
• Mechanical construction withstands elevated operating temperatures and high case pressures
• Global hazardous area certifications include options for ATEX, IECEx, and CSA compliance
