Bently Nevada 330103-08-13-10-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330103-08-13-10-02-CN provides precise, reliable measurement. This 3300 XL 8 mm proximity probe, metric version, is engineered for continuous monitoring of shaft displacement and vibration in critical rotating equipment. With a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, it withstands harsh industrial environments.

Technical Specifications

The 330103-08-13-10-02-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). The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils). Nominal probe DC resistance (RPROBE) is 7.59 ± 0.50 ohms for the 1.0 meter length. The probe case thread is M10x1 with a maximum thread engagement of 15 mm.

Industry Applications

This probe excels in steam turbines, gas turbines, compressors, and pumps where early detection of shaft vibration prevents catastrophic failure. In a typical power generation environment, the 330103-08-13-10-02-CN delivers consistent performance across a wide temperature range: -52°C to +177°C for standard probes, and up to +218°C at the tip for extended range versions. Its robust design reduces false alarms and maintenance costs, offering long-term value for plant operators.

Installation & Setup Guidance

Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. Maximum cable length between the probe and monitor is 305 meters (1,000 feet). For radial vibration monitoring, set the gap to -9 Vdc. Ensure the probe tip is clean and the target surface is smooth for accurate readings. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.

Maintenance & Reliability

Routine inspection of the probe cable and connector is recommended. The miniature coaxial ClickLoc connector provides secure, repeatable connections. The probe exhibits less than a 3% change in Average Scale Factor (ASF) after 56 days in 93% humidity per IEC 68-2-3, demonstrating excellent moisture resistance. For pressure-sensitive applications, note that probes are not pressure tested before shipment; contact the custom design department if testing is required.

Compatibility & Integration

The 330103-08-13-10-02-CN integrates seamlessly with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. When used with intrinsically safe zener barriers (per drawing 141092) or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga requirements. For non-incendive circuits (per drawing 140979), it qualifies for Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. This flexibility makes it suitable for hazardous area installations.

Selection Guide & Purchasing Advice

Before ordering, verify the unthreaded length (80 mm), overall case length (130 mm), and total length (1.0 meter) match your application. The 330103-08-13-10-02-CN includes a miniature coaxial ClickLoc connector and standard cable. For replacement or new installations, consult plcmatrix.com for availability and lifecycle status.
