Bently Nevada 330104-06-14-10-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

When unplanned downtime threatens production targets, the Bently Nevada 330104-06-14-10-02-CN 3300 XL 8 mm proximity probe provides the precise, reliable measurements you need. This probe is part of the trusted 3300 XL series, designed for non-contact vibration and position sensing on rotating machinery such as turbines, compressors, and pumps. Built with a rugged AISI 303 or 304 stainless steel case and a polyphenylene sulfide (PPS) tip, it withstands harsh industrial environments. The 330104-06-14-10-02-CN includes armor for added cable protection, making it suitable for demanding field installations.

Technical Specifications

The 330104-06-14-10-02-CN features a 6 mm unthreaded length and a 14 mm overall case length, with a total length of 1.0 meter (3.3 feet). It uses a miniature coaxial ClickLoc connector with FluidLoc cable, ensuring a secure and reliable connection. The probe tip material is polyphenylene sulfide (PPS), and the case material is AISI 303 or 304 stainless steel. Nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 ohms for the 1.0 meter length. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

This proximity probe excels in monitoring shaft vibration and axial position in critical rotating equipment. In a steam turbine train, for example, the 330104-06-14-10-02-CN provides early warning of bearing wear or imbalance, allowing maintenance engineers to schedule repairs before catastrophic failure. Its armored cable resists abrasion in high-vibration areas, reducing false readings and extending service life. The probe's robust construction also suits centrifugal compressors in oil and gas facilities, where reliable data is essential for safety and efficiency.

Installation and Setup Guidance

For accurate measurements, mount the 330104-06-14-10-02-CN with the recommended gap of 1.27 mm (50 mils) from an AISI 4140 steel target. Ensure the probe tip is clean and free of debris before installation. Use the miniature coaxial ClickLoc connector to attach the extension cable securely. Route the armored cable away from sharp edges and high-temperature surfaces to prevent damage. Verify the system power supply meets the requirements of -17.5 Vdc to -26 Vdc for non-incendive circuits, with a maximum consumption of 12 mA. For barrier installations, use -23 Vdc to -26 Vdc.

Maintenance and Reliability

From a maintenance engineer's perspective, the 330104-06-14-10-02-CN offers straightforward care. Periodically inspect the probe tip for wear or contamination, and clean it gently with a soft cloth if needed. Check the Viton O-ring seal integrity during routine outages to maintain pressure sealing. The stainless steel case resists corrosion, but verify that cable armor remains intact in high-moisture areas. Regular calibration checks against the AISI 4140 steel target ensure system accuracy. This proactive approach minimizes unexpected failures and extends probe life.

Compatibility and Integration

The 330104-06-14-10-02-CN integrates seamlessly with Bently Nevada 3300 XL 8 mm Proximitor sensors and extension cables. It accepts input from 3300-series 5 mm or 8 mm probes. The system delivers a sensitivity of less than 2 mV change in output voltage per volt change in input voltage, with an output resistance of 50 ohms. For best performance, use only genuine 3300 XL 8 mm components. Contact plcmatrix.com to verify compatibility with your existing monitoring system.

Selection Guide and Purchasing Advice

Before ordering the 330104-06-14-10-02-CN, confirm your required probe length and connector type. This model includes a 1.0 meter cable with a miniature coaxial ClickLoc connector and armor. Verify that your Proximitor sensor matches the 8 mm probe specification.
