Product Overview

The 330101-00-36-15-02-05 is a high-precision eddy current proximity sensor from the Bently Nevada 3300 XL series. This 8 mm probe is engineered for non-contacting displacement sensing, converting the physical gap between the probe tip and a conductive target into a linear voltage signal. As a critical component of Turbine Supervisory Instrumentation (TSI), it is primarily used for monitoring radial vibration, axial thrust position, and speed (Keyphasor) on high-speed rotating assets. This specific configuration features a 3.6-inch case length and a 1.5-meter integrated cable, offering a versatile solution for mid-depth machinery housing installations.

Proprietary Engineering and Reliability

This 3300 XL probe incorporates several patented design features to ensure longevity in the most taxing industrial environments:

• TipLoc Molding: A molecular-level chemical bond is formed between the probe tip and the stainless steel body. This vacuum-tight seal prevents moisture ingress and oil wicking, which are common causes of probe failure in turbomachinery.

• CableLoc Mechanism: This internal anchoring system provides 330 N (75 lbf) of pull strength, shielding the coaxial lead from mechanical strain during installation or high-vibration operation.

• Corrosion Resistance: The probe body is constructed from AISI 300 series stainless steel, and the tip is made of high-performance Polyphenylene Sulfide (PPS) plastic for superior chemical resistance.

• Enhanced RFI/EMI Immunity: Optimized circuitry ensures stable measurements even in high-interference environments, meeting European CE standards without specialized shielded conduits.

System Integration and Compliance

The 330101-00-36-15-02-05 is a foundational element for machinery protection and is fully compliant with API 670 standards:

• Total Interchangeability: All 3300 XL components are interchangeable. Probes, extension cables, and Proximitor sensors of the same system length can be swapped without manual bench calibration.

• Backward Compatibility: Electrically and physically compatible with legacy 3300 series (5 mm and 8 mm) components, facilitating cost-effective facility upgrades.

• Industrial Application: Optimized for monitoring fluid-film bearing equipment such as steam turbines, centrifugal compressors, and high-pressure pumps.

• Hazardous Area Readiness: Certified for deployment in Zone 0, 1, and 2 environments, making it suitable for global oil, gas, and power generation sectors.
