Product Overview

The Bently Nevada 330103-00-17-10-02-05 represents the pinnacle of non-contacting displacement measurement, specifically engineered for the critical protection of rotating machinery. As an integral component of the 3300 XL Proximity Transducer System, this 8mm probe provides high-fidelity analog signals to the Bently Nevada 3500 Monitoring System. It excels in detecting shaft vibration, axial position, and speed in high-performance fluid-film bearing machines such as steam turbines, centrifugal compressors, and industrial pumps. Its rugged construction ensures sub-micron precision even in volatile atmospheres, making it an indispensable asset for Emergency Shutdown (ESD) systems and predictive maintenance programs in the global energy and petrochemical sectors.

Suffix Logic and Technical Profile

Mechanical and Electrical Configuration

The specific nomenclature 330103-00-17-10-02-05 defines an imperial-threaded probe body with hazardous area certifications.

• -00 (Unthreaded Length): Indicates a 0.0-inch unthreaded section, allowing the 3/8-24 UNF body to be fully threaded for versatile depth adjustment.

• -17 (Overall Case Length): Specifies a 1.7-inch total threaded case length, optimized for mid-range bearing housing access.

• -10 (Total Length): Represents a 1.0-meter (3.3 feet) total cable length, requiring a matching extension cable to complete a 5m or 9m calibrated system.

• -02 (Connector Option): Features a miniature coaxial connector with a specialized brass cable protector for enhanced mechanical durability and fluid resistance.

• -05 (Agency Approval): Provides multi-certified protection (ATEX, IECEx, CSA) for intrinsically safe installations in explosive atmospheres.

Performance Parameters

Field Deployment Protocol

Gap Voltage Adjustment

Proper mechanical gapping is critical for signal resolution. Engineers must set the physical distance between the probe tip and the shaft while monitoring the DC bias voltage. For the 3300 XL series, a Gap Voltage of -10.00 VDC typically marks the center of the linear range. Use a digital voltmeter at the Proximitor output to verify this value during commissioning.

Coaxial Integrity and Routing

Maintain a minimum cable bend radius of 25.4 mm (1.0 inch) to prevent damage to the delicate coaxial dielectric. Always utilize the integrated brass connector protector to shield the interface from turbine oil and moisture. Ensure the cable shield is grounded only at the 3500 rack end to eliminate ground loops that can corrupt high-frequency vibration data.

Advanced Engineering Value

Thermal Stability in Volatile Zones

The 330103-00-17-10-02-05 utilizes advanced polyphenylene sulfide (PPS) tip materials and high-temperature coaxial cabling. This design ensures that the probe maintains its 200 mV/mil sensitivity regardless of thermal cycling in the machine casing. With the -05 certification, this precision remains stable even in Class I, Division 1 and Zone 0 environments.

Seamless TSI Integration

As a cornerstone of Turbine Supervisory Instrumentation (TSI), this probe integrates natively with Honeywell Experion PKS and existing Bently Nevada 3500 architectures. It captures the wide-frequency analog data necessary for advanced diagnostics, including orbit plots and shaft centerline trending, providing the technical authority needed for critical plant decision-making.

Machinery Monitoring FAQ

Q1: Can I use this 1.0-meter probe with a 5-meter Proximitor sensor?

A1: Yes, but you must pair it with a 4.0-meter extension cable. The 3300 XL system requires a total electrical length of exactly 5.0 or 9.0 meters. Any mismatch will result in significant scale factor errors.

Q2: What is the primary benefit of the -05 Agency Approval?

A2: The -05 suffix indicates the probe is multi-certified for hazardous areas. It allows for safe operation in explosive atmospheres when used with the appropriate intrinsically safe (IS) barriers.

Q3: How do I identify if the probe tip is damaged?

A3: Inspect for cracks in the PPS tip or deep scores on the face. Electrically, a DC gap voltage that stays at the "high" or "low" rail despite mechanical adjustment often indicates an internal coil failure or moisture contamination.

Q4: Is the -02 connector protector necessary?

A4: While the probe functions without it, the protector is vital in bearing housings. It prevents oil ingress into the coaxial connection, which is the leading cause of signal "glitch" and intermittent data loss in DCS interfaces.
