Product Overview

The 330101-00-77-15-02-00 is a high-precision eddy current proximity probe from Bently Nevada’s flagship 3300 XL 8 mm series. This non-contacting sensor is designed for the continuous monitoring of critical machinery, specifically targeting fluid-film bearing equipment. It excels in capturing both static displacement (thrust position) and dynamic vibration data. Engineered to meet the rigorous API 670 standards, this probe ensures maximum reliability and linear accuracy in high-temperature industrial environments. Its primary role within a Turbine Supervisory Instrumentation (TSI) system is to provide early warning of mechanical wear or shaft instability, effectively reducing the risk of catastrophic equipment failure.

Hardware Design and Durability

The construction of the 330101-00-77-15-02-00 features advanced mechanical bonding technologies. It incorporates the patented TipLoc molding process, which creates a robust seal between the probe tip and the body, and the CableLoc design, which provides a minimum pull strength of 330 N (75 lbf) to protect the connection between the probe and its lead cable. These features, combined with the gold-plated ClickLoc coaxial connector, ensure high-integrity signal transmission and resistance to corrosion and moisture infiltration.

System Integration and Benefits

As part of the 3300 XL ecosystem, this probe offers unparalleled flexibility for industrial facilities:

• Interchangeability: Probes, extension cables, and Proximitor sensors can be swapped without the need for bench calibration or matching individual components.

• Backward Compatibility: This XL-generation probe is electrically compatible with legacy 3300 5 mm and 8 mm proximity systems.

• Versatile Measurement: Ideal for use as a Keyphasor reference for speed measurements or for monitoring radial vibration and eccentricity.

• Environmental Resistance: Designed to operate reliably in the presence of oil, steam, and water, making it suitable for gas and steam turbines, compressors, and pumps.
