Description

The 330901-20-32-10-02-05 is a 3300 XL NSv Proximity Probe, part of the 3300 XL NSv Proximity Transducer System, specifically configured with a 2.0 meter (78.7 in) total length (Option C: 10), a Miniature ClickLoc connector with standard cable (Option D: 02), and agency approvals compliant with CSA, ATEX, and IECEx hazardous area standards (Option E: 05). This probe features a 5 mm tip diameter (Option B: 32) and a 2.0 inch (51 mm) unthreaded length (Option A: 20). It is engineered for non-contact displacement measurement, particularly in applications where a reduced target area or tight clearances necessitate the NSv technology. This probe is designed for use in the 3300 XL NSv Proximity Transducer System, which includes 3300 XL NSv Probes, the 330980 3300 XL NSv Proximitor Sensor, and 330930 3300 XL Extension Cables. The system provides an output that is directly proportional to the distance between the probe tip and the observed conductive surface, making it suitable for machinery vibration and position monitoring in challenging environments.

Features

• Option A: 20 (2.0 in or 51 mm) unthreaded length.
• Option B: 32 (5 mm) probe tip diameter.
• Option C: 10 (2.0 meters or 78.7 in) total probe and integral cable length.
• Option D: 02 designates a Miniature ClickLoc connector with standard cable.
• Option E: 05 provides CSA, ATEX, and IECEx hazardous area approvals.
• Non-contact measurement for machinery vibration and position.
• Suitable for applications with reduced target area or tight clearances (NSv technology).
• Compatible with 330980 3300 XL NSv Proximitor Sensors and 330930 3300 XL Extension Cables.

Applications

• Machinery vibration monitoring in small-bore or tight clearance areas.
• Shaft axial position measurement on rotating equipment.
• Relative shaft vibration monitoring.
• Aeroderivative gas turbines and other high-speed machinery with limited target geometry.
• Used in conjunction with 3300 XL NSv Proximitor Sensors for protection and condition monitoring systems.

Installation Guidelines

Ensure proper grounding and shielding practices are followed for the 3300 XL NSv system to minimize electrical noise interference. Route the integral probe cable and extension cable to avoid sharp bends and mechanical stress. The probe must be gapped correctly to the machinery shaft, ensuring the target surface is conductive and within the linear range of the transducer system. For hazardous area installations, adhere strictly to the requirements outlined by the CSA, ATEX, and IECEx certifications specific to Option E: 05. Prevent moisture ingress at cable connections.

Compliance and Certifications

• CSA: Approved for hazardous areas.
• ATEX: Approved for hazardous areas.
• IECEx: Approved for hazardous areas.
• CE Mark: Complies with applicable European Union directives.
• EAC: Customs Union certification.
