Bently Nevada 330104-12-17-10-01-05 3300 XL 8 mm Proximity Probe

Product Overview

When your rotating machinery demands precise shaft vibration and position measurements, the Bently Nevada 330104-12-17-10-01-05 3300 XL 8 mm proximity probe delivers reliable performance. This metric probe features an M10x1 threaded case with armor, a 120 mm unthreaded length, and a 170 mm overall case length. The 1.0 meter (3.3 feet) total length includes a miniature coaxial ClickLoc connector with connector protector and standard cable. With CSA, ATEX, and IECEx approvals, this probe suits hazardous area installations.

Technical Specifications

The 330104-12-17-10-01-05 operates with a nominal probe DC resistance of 7.59 ± 0.50 ohms at 1.0 m length. Its linear range spans 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 approximately –1 to –17 Vdc. The recommended gap setting for radial vibration is –9 Vdc, approximately 1.27 mm (50 mils). The probe tip material is polyphenylene sulfide (PPS), and the probe case material is AISI 303 or 304 stainless steel. The probe case thread is M10x1 with a maximum thread engagement of 15 mm. Probe weight is 323 g/m (11.4 oz).

Industry Applications

Engineers rely on the 330104-12-17-10-01-05 for critical rotating machinery monitoring in oil and gas, power generation, and heavy industrial plants. Its 2 mm linear range and –1 to –17 Vdc output provide accurate shaft vibration and position data for turbines, compressors, and pumps. The CSA, ATEX, and IECEx approvals enable installation in Zone 0, Zone 2, and Class I/II/III hazardous locations when paired with appropriate intrinsic safety barriers or non-incendive circuits per Bently Nevada drawings.

Installation Guidance

For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned conductors. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Refer to frequency response graphs for signal rolloff at high frequencies with longer cables. The probe seals differential pressure between tip and case using a Viton O-ring; probes are not pressure tested before shipment. Contact Bently Nevada custom design if pressure seal testing is required.

Maintenance and Reliability

The 330104-12-17-10-01-05 operates reliably across a standard temperature range of –52°C to +177°C (–62°F to +350°F). Extended temperature range probes handle –52°C to +218°C (–62°F to +425°F) at the tip and –51°C to +260°C (–60°F to +500°F) for cable and connector. Exposing the probe to temperatures below –34°C (–30°F) may cause premature pressure seal failure. The probe shows less than 3% change in Average Scale Factor when tested in 93% humidity per IEC 68-2-3 for up to 56 days. Periodic inspection of the probe tip and cable for physical damage is recommended.

Selection and Purchasing Advice

Before ordering the 330104-12-17-10-01-05, verify your required thread size (M10x1), unthreaded length (120 mm), overall case length (170 mm), total length (1.0 m), connector type (miniature coaxial ClickLoc with protector), and agency approvals (CSA, ATEX, IECEx).
