Bently Nevada 330904-00-18-10-01-05 3300 NSv Proximity Probe

Description

Fully threaded M8x1 metric steel probe body with stainless steel armor (Option 330904), having 0 mm unthreaded length (Option 00), 180 mm overall case length (Option 18), 1.0 m total length (Option 10), and a ClickLoc connector with connector protector (Option 01) specifies this 330904-00-18-10-01-05 configuration of the 3300 NSv proximity probe.

Designed for tight clearances and reduced target areas, this armored probe provides mechanical protection against debris and physical damage in harsh rotating machinery environments. Unlike non-armored models, the integrated stainless steel armor on this unit safeguards the coaxial cable, while the ClickLoc connector protector prevents moisture and contaminant ingress. The Option 05 designation ensures compliance with multiple international hazardous area standards, making it suitable for global industrial installations.

Features

• Option 330904 Base Design: Combines an M8x1 metric thread with robust, flexible stainless steel armor to withstand physical abrasion and debris.
• 0 mm Unthreaded Length (Option 00): Fully threaded body profile maximizes installation flexibility within compact metric tap holes.
• 180 mm Overall Case Length (Option 18): Long case design allows the probe to reach recessed shaft targets through deep machinery casings or sleeves.
• 1.0 m Total Cable Length (Option 10): Direct 1.0-meter integrated probe lead length connects seamlessly to an extension cable.
• ClickLoc Connector with Protector (Option 01): Features a miniature male coaxial ClickLoc connector pre-installed with a fluorosilicone connector protector to block moisture and chemical ingress.
• Option 05 Multiple Approvals: Certified for intrinsically safe and non-incendive installations under CSA, ATEX, and IECEx agency approvals.
• Eddy-Current Sensing Technology: Specifically designed for tight targets with an Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil).

Applications

The 330904-00-18-10-01-05 probe is engineered for high-speed rotating machinery with limited physical access or narrow target geometries. Typical application environments include:

• Radial vibration and axial position monitoring on shafts smaller than 20 mm (0.8 inches).
• Small-bore machinery, high-speed gearboxes, and aeroderivative gas turbines.
• Centrifugal compressors and industrial pumps requiring ruggedized metric-threaded sensors.
• Harsh chemical, petrochemical, and power generation environments demanding armored cable protection.
• Hazardous areas requiring certified intrinsically safe (Ex ia) instrumentation.

Installation Guidelines

• Thread Engagement Limit: For M8x1 probe cases, the maximum thread engagement length is 12 mm. Avoid exceeding this to prevent binding during installation.
• Probe Case Torque: For M8x1 probe cases, the recommended torque is 5.1 N-m (45 in-lb), and the maximum rated torque is 7.3 N-m (65 in-lb). Do not over-torque.
• Minimum Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for both armored and unarmored cable portions to prevent signal attenuation or physical damage.
• Connector Connection: Ensure that the ClickLoc connectors are kept clean and dry. Use the pre-installed connector protector (Option 01) to seal the female/male connection.
• System Length Matching: Ensure that the combined length of the probe and the extension cable matches the total calibrated length of the 3300 XL NSv Proximitor Sensor (either 5.0 m or 7.0 m).

Compliance and Certifications

• EMC: European Community Directive 2014/30/EU, standards EN 61000-6-2 (Immunity) and EN 61000-6-4 (Emissions) for Industrial Environments.
