Brand New Bently Nevada 330702-00-26-10-11-05. In Stock, Original Pack, Sealed. High-range 11mm probe for 3500 system. Model Number verified. Fast Shipping.

Product Overview

The Bently Nevada 330103-00-14-50-02-00 is a cornerstone of the 3300 XL 8mm Proximity Transducer System, engineered for unparalleled reliability in machinery protection. This 8mm proximity probe serves as a critical sensory input for the Bently Nevada 3500 monitoring platform, providing high-precision data on shaft vibration, axial position, and speed. Designed for the most demanding Turbine Supervisory Instrumentation (TSI) applications, it enables plant operators to detect micro-level mechanical deviations before they escalate into catastrophic failures. Its non-contacting eddy current technology ensures stable performance in high-speed rotating assets such as steam turbines, centrifugal compressors, and large pumps, forming a vital link in Emergency Shutdown (ESD) and predictive maintenance infrastructures.

Component Configuration Matrix

Understanding the Part Number Suffixes

The specific suffix logic for the 330103 series determines the mechanical footprint and cable profile required for successful site integration.

-00 (Unthreaded Length)

This indicates a 0.0-inch unthreaded body section. The 3/8-24 UNF body remains fully threaded to allow for maximum installation flexibility and depth adjustment within the probe bracket or housing.

-14 (Overall Case Length)

Specifies a 1.4-inch total threaded case length. This dimension provides the necessary reach for medium-depth mounting scenarios while maintaining a rigid profile to resist vibration-induced signal noise.

-50 (Total Length)

Represents a 5.0-meter (16.4 feet) total integrated cable length. This specific configuration is designed to connect directly to a 5-meter Proximitor sensor without the need for an additional extension cable, reducing potential failure points in the signal path.

-02 (Connector Option)

Equipped with a miniature coaxial connector and an integrated brass cable protector. This hardware enhancement significantly improves the mechanical durability of the connection point and prevents oil or moisture ingress from grounding the signal.

-00 (Agency Approval)

Designates the standard version without specific hazardous area certifications, ideal for general industrial applications where explosive gas protection is not a site requirement.

Technical Specifications

Field Calibration and Commissioning

Mechanical Gap Alignment

Achieving accurate vibration readings depends entirely on the initial mechanical gap. Engineers must set the physical distance between the probe tip and the shaft while monitoring the DC Gap Voltage at the Proximitor. For a standard 3300 XL system, a voltage of -10.00 VDC indicates the probe is positioned at the center of its linear region. Finalize the locknut torque only after verifying this voltage to prevent the sensor from "clipping" during high-amplitude vibration events.

Cable Handling and Routing

The 5.0-meter integrated cable requires careful routing to maintain signal integrity. Technicians should maintain a minimum bend radius of 25.4 mm (1.0 inch). Always ensure the cable is secured within conduit or along tray systems to prevent physical damage. Ground the cable shield only at the 3500 monitoring rack end to prevent ground loops that introduce electrical interference into the vibration spectrum.

High-Performance Engineering Traits

Signal Stability in Extreme Environments

The 330103-00-14-50-02-00 utilizes advanced polyphenylene sulfide (PPS) for the probe tip, providing exceptional resistance to synthetic lubricants, caustic chemicals, and intense thermal cycling. This material choice ensures the 200 mV/mil scale factor remains stable over years of operation, even when exposed to the high temperatures inside turbine casings.

Seamless DCS and TSI Integration

This transducer system bridges the gap between mechanical motion and digital oversight. It integrates natively with Honeywell Experion PKS, Emerson DeltaV, and other leading DCS platforms via the Bently Nevada 3500 interface. By delivering wide-frequency response signals, it enables sophisticated diagnostics including orbit plots and shaft centerline trending, empowering maintenance teams with actionable machinery intelligence.

Technical Knowledge Base

Q1: Can I use this 5.0-meter probe with a 9.0-meter Proximitor?

A1: No. The system must be electrically matched. A 5.0-meter probe is designed for a 5-meter system. Using it with a 9-meter Proximitor will cause significant scale factor errors and inaccurate vibration readings.

Q2: What is the benefit of the -02 connector protector?

A2: The brass protector shields the delicate coaxial connection from turbine oil and moisture ingress. It also provides mechanical strain relief, which is vital in high-vibration areas to prevent the cable from loosening.

Q3: How do I identify a failing 330103 probe?

A3: Monitor the DC bias. If the voltage rails to 0V or -24V regardless of the mechanical gap, it typically indicates a short or an open circuit in the internal coil or the integrated cable.

Q4: Is the 3300 XL series backward compatible?

A4: Yes, the 3300 XL 8mm components are generally compatible with non-XL 3300 5mm and 8mm systems, though we recommend replacing the entire transducer string to ensure maximum linearity and performance.
