Product Overview

The 330104-14-19-10-11-00 is a high-precision eddy current proximity transducer belonging to the Bently Nevada 3300 XL 8 mm series. This metric-threaded armored probe is designed for non-contacting displacement measurements, converting the distance between the probe tip and a conductive target into a linear voltage signal. It is a critical component for Turbine Supervisory Instrumentation (TSI), facilitating continuous monitoring of radial vibration, axial thrust, and shaft position. This specific configuration is optimized for deep-reach installations, featuring extended unthreaded and case lengths to accommodate specialized machine housing requirements.

Durability and Mechanical Engineering

This 3300 XL probe incorporates patented manufacturing technologies to ensure longevity in the most taxing industrial environments. The probe tip is constructed from high-performance Polyphenylene Sulfide (PPS) plastic, which is hermetically bonded to the sensor body using the TipLoc molding process. This ensures a vacuum-tight seal that resists chemical degradation and thermal cycling.

The CableLoc design provides superior pull-out strength of up to 330 N (75 lbf), while the flexible stainless steel armor shields the coaxial lead from mechanical abrasion and accidental severing during machine maintenance. Additionally, the system maintains a standard scale factor of 7.87 V/mm (200 mV/mil) for AISI 4140 steel targets.

Industrial Applications and System Integration

The 330104-14-19-10-11-00 is a foundational tool for machinery health monitoring and predictive maintenance:

• Vibration Monitoring: Ideal for measuring radial shaft vibration in fluid-film bearing machines such as compressors and turbines.

• Position Sensing: Used for axial thrust measurements to prevent rotor-to-stator contact.

• Speed Detection: Functionally compatible as a Keyphasor sensor for RPM and phase angle measurements.

• System Compatibility: Fully interchangeable with 3300 XL Proximitor sensors and extension cables. It also maintains backward compatibility with legacy 3300 series 5 mm and 8 mm components.

• EMI/RFI Immunity: Advanced circuitry ensures high signal-to-noise ratios even in high-interference environments, meeting CE requirements without specialized shielded conduit.
