Датчики приближения Bently Nevada 330901-00-09-05-02-00 3300 NSv

Description

Option 00 (0.0 in unthreaded length) and Option 09 (0.9 in case length) specify the configuration of this 3300 NSv proximity probe — 330901-00-09-05-02-00. This standard mount, non-armored probe features a 1/4-28 UNF thread and is used in machinery with tight physical clearance and reduced target area constraints, such as small centrifugal air compressors, refrigeration compressors, and process gas compressors. With a short 0.9-inch fully threaded case and a 0.5-meter (20-inch) total probe length, this configuration allows for non-contact displacement measurement in highly restricted internal enclosures where standard-sized probes cannot be installed.

This variant uses a standard 75-ohm coaxial cable with a miniature ClickLoc coaxial connector (Option 02) without an integrated connector protector, facilitating compact cable routing. Because it is optioned with no agency approvals (Option E = 00), this probe is used for general-purpose, non-hazardous industrial installations. It is compatible with the Bently Nevada 330980 Proximitor Sensor and 330930 extension cables, providing a standard scale factor of 7.87 V/mm (200 mV/mil) over a 1.5 mm (60 mils) linear range when paired as a complete transducer system.

Features

• Option 00 specifies a fully threaded probe case with 0.0 inches of unthreaded length for maximum mounting flexibility.
• Option 09 provides a compact 0.9-inch overall case length suitable for tight internal installation envelopes.
• Option 05 provides a 0.5-meter (20-inch) FEP-insulated coaxial cable, minimizing routing slack inside the machine housing.
• Option 02 provides a miniature coaxial ClickLoc connector with a standard unarmored cable, enabling secure, click-to-lock connections.
• Option 00 specifies that agency approvals are not required, serving cost-effective general-purpose installations.
• Standard 1/4-28 UNF thread without stainless steel armor for straightforward mounting in pre-tapped bores.
• Polyphenylene sulfide (PPS) tip material with patented TipLoc molding ensures a robust bond between the probe tip and case.
• Patented CableLoc design provides up to 220 N (50 lb) of cable pull strength.

Applications

• Small-bore machinery and high-speed rotating equipment with tight spatial constraints.
• Centrifugal air compressors and refrigeration compressors.
• Process gas compressors and fluid-filmed bearing machinery.
• Radial vibration, radial position, and axial position monitoring on small shaft diameters.

Installation Guidelines

• Gap Setting: Set the probe gap to the nominal target of 1.0 mm (40 mils) or approximately -9.0 Vdc to -10.0 Vdc output at the Proximitor Sensor for axial or radial measurements.
• Thread Engagement: Do not exceed 0.375 inches of thread engagement on 1/4-28 UNF probe cases to avoid potential binding.
• Case Torque: Torque the probe case to 5.1 N m (45 in lb) nominal during installation. Do not exceed the maximum limit of 7.3 N m (65 in lb).
• Cable Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the probe cable to prevent attenuation or damage to the internal FEP insulation.
• Connector Tightening: ClickLoc connectors should be joined finger-tight; do not exceed 0.56 Nm (5 in lb) of torque.
• Moisture Protection: In environments with high humidity or exposure to liquids, protect the ClickLoc connections using silicone tape or connector protectors.

Compliance and Certifications

• RoHS: Compliant with European Community Directive 2011/65/EU and China RoHS standards.
• Electromagnetic Compatibility (EMC): Compliant with EMC Directive 2014/30/EU, standards EN 61000-6-2 (Immunity) and EN 61000-6-4 (Emissions).
• Functional Safety: SIL 2 (HFT=0) and SIL 3 (HFT=1) capable when used as part of a safety instrumented system.
• Agency Approval Option E = 00: General Purpose (no hazardous area approvals required).
