Bently Nevada 330104-00-07-05-01-05 3300 XL 8 mm Proximity Probe

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 330104-00-07-05-01-05 provides precise measurement. This 3300 XL 8 mm proximity probe uses a metric M10x1 thread and includes armor for durability. It delivers a linear range of 2 mm (80 mils) for accurate displacement readings. Designed for harsh industrial environments, it carries CSA, ATEX, and IECEx approvals.

Technical Specifications

The probe operates with a nominal DC resistance of 7.45 ± 0.50 ohms at 0.5 meter length. Its standard temperature range spans -52°C to +177°C (-62°F to +350°F). An extended range option supports probe tip temperatures up to +218°C (+425°F) and cable temperatures up to +260°C (+500°F). The probe case material is AISI 303 or 304 stainless steel, and the tip is polyphenylene sulfide (PPS). Maximum thread engagement is 15 mm. Recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils).

Industry Applications

This proximity probe excels in rotating machinery monitoring, such as turbines, compressors, and pumps. Its 2 mm linear range and high-temperature capability suit steam turbines and gas compressors. The CSA/ATEX/IECEx approvals allow installation in hazardous areas, including Class I, Zone 0 and Zone 2 environments when used with appropriate barriers or isolators.

Installation & Setup Guidance

Mount the probe using the recommended torque of 11.2 N·m (100 in·lbf) and do not exceed 33.9 N·m (300 in·lbf). Use 3-conductor shielded triad cable with tinned field wiring. Maximum field wiring length is 305 meters (1,000 feet) between the probe and monitor. Set the gap to -9 Vdc for radial vibration measurement. Ensure the probe tip is clean and the target surface is smooth.

Maintenance & Reliability

Inspect the probe cable and connector periodically for damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent pressure seal failure. The probe seals differential pressure with a Viton O-ring; contact the custom design department if pressure testing is required. The probe weight is 323 g/m (11.4 oz).

Selection Guide & Purchasing Advice

Verify the thread type (M10x1), cable length (0.5 meter), and agency approvals (CSA, ATEX, IECEx) match your application. For hazardous area use, confirm the correct intrinsic safety barrier or galvanic isolator per drawing 141092 or non-incendive circuit per drawing 140979. plcmatrix.com offers this Bently Nevada 330104-00-07-05-01-05 with expert support.
