Product Overview

The 330703-000-100-10-01-CN is a high-precision non-contacting displacement sensor from the Bently Nevada 3300 XL 11 mm series. This probe is specifically engineered for industrial applications that require a wider linear measurement range than standard 8 mm sensors can provide. By utilizing eddy current technology, it accurately tracks radial vibration and axial thrust position on large-scale rotating machinery. This specific configuration features a metric M14 x 1.5 threaded body and is optimized for the Chinese industrial market, ensuring compliance with regional regulatory standards while maintaining the global performance benchmarks of the 3300 XL transducer family.

Technical Configuration

The model 330703-000-100-10-01-CN is defined by the following technical parameters:

• Probe Diameter: 11 mm tip for extended linear range.

• Thread Specification: M14 x 1.5 metric threads, non-armored cable.

• Unthreaded Length: 0 mm (fully threaded case).

• Overall Case Length: 100 mm.

• Total System Length: 1.0 Meter (approx. 3.3 feet).

• Connector Option: Miniature coaxial ClickLoc connector with integrated connector protector (01 option).

• Agency Approval: CN-specific certification for regional industrial compliance.

• Linear Range: 4.0 mm (160 mils) when used with a matching 3300 XL 11 mm Proximitor.

Performance and Durability Characteristics

Built to operate within Turbine Supervisory Instrumentation (TSI) systems, the 330703 series offers several engineering advantages:

• Extended Measurement Envelope: Provides nearly double the linear range of 8 mm systems, essential for monitoring large rotors with significant thermal expansion or axial float.

• Chemical and Oil Resistance: The probe tip is constructed from high-grade Polyphenylene Sulfide (PPS) and is chemically bonded to the stainless steel body (TipLoc technology) to prevent process fluid ingress.

• Mechanical Integrity: Features CableLoc technology, providing a minimum of 220 N (50 lb) of pull strength between the probe and the cable to prevent accidental disconnection or signal failure in high-vibration environments.

• Gold-Plated ClickLoc Connectors: The self-locking coaxial connectors are gold-plated to ensure a low-impedance, corrosion-resistant electrical path, critical for maintaining signal fidelity over long service lives.

  
  

Primary Industrial Applications

This 11 mm proximity probe is a vital component for the protection of high-capital assets, including:

• Steam and Gas Turbines: Measuring thrust bearing wear and axial displacement in large-frame power generation units.

• Hydroelectric Generators: Monitoring shaft dynamic motion and radial vibration on large-diameter vertical or horizontal shafts.

• Industrial Compressors: Providing early warning of rotor imbalance or misalignment in heavy-duty process air and gas compressors.

• Predictive Maintenance: Generating real-time data for Bently Nevada 3500 series racks and System 1 software to optimize machinery uptime.
