Product Overview

The 330101-00-80-10-02-00 is a high-precision eddy current proximity sensor from Bently Nevada’s 3300 XL series. This 8 mm probe is engineered for non-contacting displacement measurements, converting the physical gap between the probe tip and a conductive target into a linear voltage signal. As a core component of Turbine Supervisory Instrumentation (TSI), it provides critical data for radial vibration, axial thrust position, and eccentricity monitoring in high-speed rotating machinery. This specific configuration features a 3/8-24 UNF threaded body with an 8.0-inch case length, making it ideal for deep-reach installations through machine housings or bearing pedestals.

Technical Configuration

• Linear Range: 2.0 mm (80 mils)

• Scale Factor: 7.87 V/mm (200 mV/mil) when paired with a 3300 XL Proximitor

Advanced Engineering and Durability

The 3300 XL 8 mm probe system incorporates several proprietary manufacturing improvements to ensure long-term stability and resistance to harsh industrial environments:

• TipLoc Molding: A patented process that creates a molecular-level bond between the Polyphenylene Sulfide (PPS) tip and the stainless steel body, preventing delamination and ensuring a vacuum-tight seal against oil and moisture.

• CableLoc Mechanism: A robust internal anchoring system providing 330 N (75 lbf) of pull strength, protecting the coaxial lead from mechanical strain during installation.

• Gold-Plated ClickLoc: The probe utilizes a corrosion-resistant, gold-plated miniature coaxial connector that locks securely with an audible "click," ensuring a vibration-proof connection without specialized tools.

• FluidLoc Technology: The integrated lead is designed to prevent the "wicking" of process fluids through the cable to the Proximitor sensor, maintaining signal integrity.

Industrial Applications and Integration

The 330101-00-80-10-02-00 is a foundational element for machinery health monitoring and is fully compliant with API 670 standards:

• Machinery Protection: Essential for monitoring fluid-film bearing equipment such as steam turbines, centrifugal compressors, and high-speed pumps.

• System Compatibility: Components are fully interchangeable; probes, extension cables, and Proximitor sensors of the same system length can be swapped without manual bench calibration.

• Keyphasor Capability: Optimized for providing timing and speed reference signals for phase angle measurements and RPM tracking.

• RFI/EMI Immunity: Advanced circuitry ensures stable signals in high-interference environments, meeting European CE requirements without the use of specialized shielded conduit.
