Bently Nevada 330104-03-09-50-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime strikes rotating machinery, the Bently Nevada 330104-03-09-50-02-CN 3300 XL 8 mm Proximity Probe provides the precise, reliable measurements needed to prevent catastrophic failures. This probe is part of the proven 3300 XL series, designed for non-contact vibration and position monitoring in turbines, compressors, and pumps. With its armored construction and country-specific approval (CN), it meets rigorous safety and performance standards, reducing the risk of costly production halts.

Technical Specifications Breakdown

The 330104-03-09-50-02-CN offers a total length of 5.0 meters (16.4 feet) with a miniature coaxial ClickLoc connector, ensuring secure and quick installation. Its probe tip is made of polyphenylene sulfide (PPS), providing excellent chemical resistance and durability. The probe case is constructed from AISI 303 or 304 stainless steel, offering robust protection in harsh environments. The nominal probe DC resistance is 8.73 ± 0.50 Ω, ensuring consistent signal transmission. These specs translate to reliable performance over long cable runs, reducing signal degradation and maintenance costs.

Industry Applications

In the oil and gas sector, this probe monitors shaft vibration in large compressors, enabling early detection of bearing wear. For power generation, it tracks turbine rotor position, preventing contact with stationary parts. The probe’s ability to seal differential pressure between tip and case (using a Viton O-ring) makes it ideal for high-pressure steam environments. By catching issues early, operators avoid expensive emergency repairs and extend equipment life.

Installation & Setup Guidance

Install the 330104-03-09-50-02-CN with the probe gapped at 1.27 mm (50 mils) to an AISI 4140 steel target for optimal accuracy. Use the M10 x 1 thread for secure mounting. Ensure the extension cable and Proximitor sensor are genuine 3300 XL 8 mm components to maintain system accuracy. Proper installation minimizes false readings and reduces calibration time, directly lowering labor costs.

Maintenance & Reliability

The PPS tip and stainless steel case resist corrosion and wear, extending service intervals. Periodic inspection of the cable and connector for damage is recommended. The probe operates reliably across a wide ambient temperature range (e.g., T3: -55°C to +120°C for EPL Ga/Gc). This durability reduces replacement frequency, offering a lower total cost of ownership over the equipment’s life.

Compatibility & Integration

This probe accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe and extension cable. It requires a -17.5 Vdc to -26 Vdc power supply (12 mA max consumption) and delivers a sensitivity of less than 2 mV change per volt change in input voltage. When used with intrinsic safety barriers or galvanic isolators, it supports hazardous area installations (Class I, Zone 0). This flexibility allows integration into existing monitoring systems without major redesign, saving engineering costs.

Buying Guide & Purchasing Advice

Before ordering, verify the total length option (50 = 5.0 m) and connector type (miniature coaxial ClickLoc) match your application. Confirm the agency approval (CN) meets your regional requirements.
