Bently Nevada 330902-00-60-10-02-05 3300 NSv Proximity Probe

Description

Option 00 (0.0 in unthreaded length) and Option 60 (6.0 in overall case length) specify this stainless-steel armored 1/4-28 UNF threaded configuration — 330902-00-60-10-02-05 3300 NSv proximity probe.

This transducer probe is armored with stainless steel to protect the FEP-insulated coaxial cable from mechanical wear and abrasion in demanding industrial areas, separating it from the standard unarmored 330901 variant. Featuring a 1.0 m (39 in) total probe length and a miniature coaxial ClickLoc connector, this configuration is optimized for tight-clearance, small-bore rotating machinery installations requiring multi-agency hazardous area approvals (Option 05).

Features

• 1/4-28 UNF-2A thread with integrated stainless steel armor to protect against physical wear and abrasion.
• 0.0 in unthreaded length (fully threaded case) paired with 6.0 in overall case length.
• 1.0 meter (39 in) integrated probe cable terminated with a miniature coaxial ClickLoc connector.
• Option 05 multiple agency approvals for hazardous industrial zones.
• Gold-plated brass ClickLoc connectors designed to resist loosening over time.
• Polyphenylene sulfide (PPS) tip material with robust patented TipLoc molding.

Applications

• Small-bore rotating machinery monitoring.
• Aeroderivative gas turbine vibration and position sensing.
• High-speed equipment installations with restricted target geometry.
• Centrifugal compressors and industrial pumps with limited mounting clearances.

Installation Guidelines

• Probe Thread Engagement: Maximum recommended thread engagement for 1/4-28 UNF-2A threads is 0.375 in. Do not exceed this limit to avoid binding.
• Probe Case Torque: Tighten standard mount cases to a recommended torque of 5.1 N m (45 in lb). Do not exceed the maximum rated torque of 7.3 N m (65 in lb).
• Connector Protection: Use of connector protectors is recommended for all probe-to-extension cable connections to prevent liquid ingress.
• Cable Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) for the armored cable during routing.
• Pressure Seal Integrity: Exposing the probe to temperatures below -34 degC (-30 degF) for sustained periods may cause premature failure of the pressure seal.

Compliance and Certifications

• European Community Directives: EMC Directive 2014/30/EU, RoHS Directive 2011/65/EU
• EMC Standards: EN 61000-6-2, EN 61000-6-4
• Functional Safety: SIL 2 (HFT = 0), SIL 3 (HFT = 1)
• Hazardous Area Approvals: Approved for Class I, Division 1 & 2 and Zone 0, 1 & 2 environments when used with compatible barriers.
