Description

The 330904-05-14-05-02-05 is a 3300 XL NSv proximity probe with an M8 x 1 thread and integral stainless steel armor. This configuration features a 50 mm unthreaded length (Option 05), a 140 mm case length (Option 14), and a 0.5 meter total system length (Option 05). Designed for 3300 XL NSv transducer systems, this probe utilizes a miniature coaxial ClickLoc connector (Option 02) and includes Multiple Agency Approvals (Option 05).

The 3300 XL NSv proximity transducer system is engineered for applications where space constraints or small target geometry limit the effectiveness of standard probes. It is suitable for radial vibration and axial position measurements on small-bore machinery, aeroderivative turbines, and high-speed equipment. The NSv system is compatible with 3300 NSv extension cables and 3300 XL NSv Proximitor sensors, providing precise non-contact displacement measurement in demanding industrial environments.

Features

• Threaded Configuration: M8 x 1 thread, armored, compliant with 330904 base model specifications.
• Dimensions: 50 mm unthreaded length; 140 mm case length.
• Cable and Connector: 0.5 meter total length with miniature coaxial ClickLoc connector and standard cable.
• Robust Design: Features TipLoc molding for a reliable bond between the probe tip and body, and CableLoc design for 220 N (50 lb) pull strength.
• Approvals: Multiple Agency Approvals (CSA, ATEX, IECEx) for hazardous area operation.

Applications

• Radial vibration and radial position measurements on fluid-filmed bearing machines.
• Axial (thrust) position measurements for small target applications.
• Tachometer and zero-speed measurements.
• Phase reference (Keyphasor) signal generation.
• Machinery with tight installation requirements, such as centrifugal air and refrigeration compressors.

Installation Guidelines

• Ensure the probe is installed with the correct gap as specified in the 3300 XL NSv Proximitor sensor manual.
• Use connector protectors on the probe-to-extension cable connection to prevent fluid ingress.
• Verify hazardous area installation requirements comply with relevant Bently Nevada drawings (e.g., 141092 for intrinsic safety).
• Mounting hardware for the Proximitor sensor (panel or DIN rail) should be selected based on the specific system assembly requirements.

Compliance and Certifications
