Product Overview

The Bently Nevada 330103-00-04-10-02-05 stands as a cornerstone of the 3300 XL 8mm Proximity Transducer System, delivering unparalleled reliability in non-contact displacement and vibration measurements. Engineered specifically for critical rotating machinery, this probe converts shaft motion into a high-fidelity electrical signal that the 3500 Monitoring System or Distributed Control Systems (DCS) can interpret for early fault detection. It excels in harsh industrial environments, providing essential data for radial vibration, axial position, and speed measurements on turbines, compressors, and pumps. By offering a standard linear range of 2.0 mm (80 mils), this probe ensures that even subtle mechanical instabilities are detected before they escalate into costly catastrophic failures or unplanned outages.

Model Configurator and Suffix Logic

The part number 330103-00-04-10-02-05 follows a strict engineering code to define mechanical fit and hazardous area compliance.

00 (Unthreaded Length): This indicates a 0.0-inch unthreaded portion, meaning the probe body features full threads for maximum mounting flexibility within a bracket or housing.

04 (Overall Case Length): Specifies an overall case length of 0.4 inches. This compact design facilitates installation in tight mechanical clearances where a standard long-body probe would interfere with internal components.

10 (Total Length): Defines a 1.0-meter (3.3 feet) total cable length. For system calibration, this must match the expected input of the associated Proximitor Sensor to maintain the 200 mV/mil scale factor.

02 (Connector and Cable Option): Includes a miniature coaxial connector with a standard cable. The connector features a gold-plated center pin for superior signal conductivity and corrosion resistance.

05 (Agency Approval): Designates multiple approvals, including CSA, ATEX, and IECEx certifications for use in intrinsically safe and non-incendive hazardous areas.

Engineering Installation Guide

Achieving peak performance requires precise mechanical gapping. Utilize a calibrated digital multimeter to monitor the DC Gap Voltage from the Proximitor. For most 3300 XL applications, the probe is gapped to -10.0 VDC, representing the center of the linear region. Ensure the target material is AISI 4140 steel; any deviation in metallurgy will require a scale factor correction in the 3500 rack configuration.

Route the coaxial cable through a dedicated conduit to shield the high-impedance signal from electromagnetic interference. Maintain a minimum bend radius of 25.4 mm (1 inch). Over-tightening the probe during installation can damage the threads or internal coil; always use the specified torque values for the mounting bracket or probe housing. If installing in a wet or oily environment, utilize connector protectors to prevent moisture ingress at the coaxial junction.

Machinery Protection Advantages

The 330103-00-04-10-02-05 is designed for seamless integration with Turbine Supervisory Instrumentation (TSI) and Honeywell Experion PKS platforms. Its advanced Ryton® probe tip is chemically resistant to synthetic lubricants and high-temperature steam, ensuring longevity in the most punishing machinery environments. The 3300 XL technology effectively suppresses "cross-talk" between adjacent probes, allowing for high-density mounting in radial bearings. This reliability is vital for the automated logic of Emergency Shutdown Systems (ESD), where a stable signal prevents both missed trips and nuisance alarms.

Delivery Information

Delivery time: 3-5 days when payment finish, BY DHL/FEDEX/UPS.

We provide "Original Pack" assurance, shipping every unit in its factory-sealed anti-static industrial packaging to maintain calibration integrity and ensure the probe arrives in pristine condition.

Technical FAQs

Q1: Can I pair this 1.0-meter probe with a 9.0-meter extension cable?

A1: Yes. The 3300 XL system is designed for a total electrical length of 5.0 or 9.0 meters. A 1.0-meter probe is typically paired with a 4.0-meter or 8.0-meter extension cable to reach the Proximitor Sensor.

Q2: What happens if the gap voltage is set outside of -10.0 VDC?

A2: If the gap is too close (e.g., -4.0 VDC) or too far (e.g., -16.0 VDC), the probe enters the non-linear region, leading to distorted vibration readings and potentially triggering a "Not OK" status in the monitor.

Q3: Is the 330103-00-04-10-02-05 compatible with older 3300 series Proximitors?

A3: While it may function, the 3300 XL probe is optimized for 3300 XL Proximitor Sensors. Using it with non-XL components may result in a scale factor shift from the standard 200 mV/mil.

Q4: How does the "05" approval affect installation?

A4: The "05" approval means the probe is certified for hazardous areas worldwide. You must follow the specific control drawings provided by Bently Nevada to maintain the system's Intrinsically Safe (IS) rating.
