Bently Nevada 330104-00-17-90-02-CN 3300 XL 8 mm Proximity Probe, Metric

Product Overview

The Bently Nevada 330104-00-17-90-02-CN is a 3300 XL 8 mm proximity probe designed for precise, non-contact vibration and position measurement in rotating machinery. This metric probe features an M10x1 thread with armor, a 170 mm overall case length, and a 9.0-meter (29.5 feet) cable with a miniature coaxial ClickLoc connector. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel, ensuring durability in demanding conditions. As a maintenance engineer, you will appreciate its robust design and straightforward installation, which minimize downtime and simplify routine checks.

Technical Specifications

The 330104-00-17-90-02-CN offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target and extending to 2.3 mm (90 mils), corresponding to –1 to –17 Vdc. The recommended gap setting for radial vibration is –9 Vdc, approximately 1.27 mm (50 mils). The nominal probe DC resistance (RPROBE) is 9.87 ± 0.50 ohms for the 9.0-meter length. Field wiring accepts 0.2 to 1.5 mm² (16 to 24 AWG) with a maximum cable length of 305 meters (1,000 feet) between the probe and monitor. The probe operates and stores in temperatures from –52°C to +177°C (–62°F to +350°F), with extended range options available for the tip and cable. It withstands 93% humidity per IEC 68-2-3 with less than 3% change in Average Scale Factor.

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of turbines, compressors, pumps, and motors in oil and gas, power generation, and heavy manufacturing. Its PPS tip and stainless steel case resist harsh chemicals and high temperatures, making it suitable for critical rotating assets where reliability is paramount. The 9.0-meter cable length allows flexible placement away from the machine, while the ClickLoc connector ensures secure, quick connections during installation or replacement.

Installation & Setup Guidance

Mount the probe with the M10x1 thread, ensuring a maximum thread engagement of 15 mm. Use a 3-conductor shielded triad cable with tinned wiring for field connections. Set the gap to –9 Vdc (approximately 1.27 mm) for radial vibration monitoring. Verify the probe is not pressure tested before shipment; if a pressure seal test is required, contact the custom design department. For intrinsic safety, install with approved zener barriers per drawing 141092 or galvanic isolators for Class I, Zone 0 environments.

Maintenance & Reliability

From a maintenance perspective, the 330104-00-17-90-02-CN requires minimal upkeep. Inspect the probe and cable periodically for physical damage, especially near the connector and thread. Avoid exposing the probe to temperatures below –34°C (–30°F) to prevent premature pressure seal failure. The Viton O-ring seal maintains differential pressure integrity, but regular visual checks are recommended. For extended life, keep the probe tip clean and free from debris.
