330103-00-08-05-02-05 Bently Nevada 3300 XL 8mm Probe

Product Overview

The Bently Nevada 330103-00-08-05-02-05 is a high-performance 8mm proximity probe optimized for the Series 3300 XL transducer system. Engineered for non-contacting measurement of shaft vibration and position, this model features an extended 80mm case length and a fully unthreaded design for specific mounting requirements. The 0.5-meter integral cable utilizes the gold-plated ClickLoc connector system, providing a robust, moisture-resistant link to extension cables. With its ability to operate in temperatures ranging from -52 to +177 Degrees Celsius, this probe is the industry benchmark for reliability in critical rotating equipment monitoring.

Core Technical Advantages

Superior Chemical and Thermal Resistance

The probe tip is constructed from high-grade Polyphenylene sulfide (PPS), while the housing is made from 303/304 stainless steel. This combination ensures maximum resistance to industrial corrosive agents and maintains signal integrity in extreme thermal conditions. For high-pressure environments, a built-in Viton O-ring provides a reliable differential pressure seal between the tip and the case.

Global Compliance for Hazardous Areas

Equipped with multi-agency approvals (CSA, ATEX, and IECEx), the 330103-00-08-05-02-05 is suitable for use in Class I, Zone 0 and Division 1 environments. It meets Intrinsic Safety (ia) and Non-incendive (nA, ec) requirements, allowing for safe deployment in proximity to explosive gases (Groups A, B, C, D) and dust (Groups E, F, G).

Precision Measurement Performance

This probe provides a clear linear range of 2.0 mm (80 mils), optimized for radial vibration gap settings of -9 Vdc. The advanced design ensures less than a 3% change in Average Scale Factor (ASF) even in 93% relative humidity, delivering stable, repeatable data to your Bently Nevada monitoring system.

Technical Specifications

Installation and Maintenance

• Gap Calibration: For radial vibration monitoring, set the initial gap to -9 Vdc (approximately 1.27 mm) against the target surface.
• Mounting Torque: Ensure the thread engagement does not exceed 15mm to avoid mechanical distortion of the sensor case.
• Pressure Sealing: While equipped with a Viton O-ring, avoid exposing the probe to temperatures below -34 Degrees Celsius if a pressure-tight seal is required for the application.

Technical FAQs

Q1: What does the 00 unthreaded length option imply?

A1: An unthreaded length of 00 means the entire 80mm case is threaded with M10x1, allowing for maximum flexibility in depth adjustment during installation.

Q2: What is the recommended shipping weight for logistics?

A2: The net probe weight is approximately 0.34 kg. For shipping, we recommend calculating based on 0.55 kg to account for protective anti-static packaging and a reinforced industrial carton.

Q3: How far can the field wiring be extended?

A3: You can run up to 305 meters (1,000 feet) of 3-conductor shielded triad cable between the Proximitor Sensor and the monitor without significant signal loss.
