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

Description

The 330902-00-10-10-02-05 configuration specifies a 3300 NSv proximity probe with integrated flexible stainless steel armor, a fully threaded 1/4-28 UNF case (0.0 in unthreaded length and 1.0 in case length), a 1.0 m total cable length, standard coaxial ClickLoc connector, and comprehensive Option 05 multiple hazardous area approvals.

As a critical element of the Bently Nevada 3300 XL NSv Proximity Transducer System, this non-contacting eddy-current sensor is engineered specifically for applications with limited clearance or reduced target geometries, such as small-bore rotating machinery and aeroderivative gas turbines. The robust flexible AISI 302 stainless steel armor shields the 75-ohm coaxial cable against physical damage, mechanical cuts, and industrial wear. It operates by outputting a voltage directly proportional to the distance between the probe tip and the target, enabling highly accurate dynamic shaft vibration, axial position, and speed measurements when paired with a matching 330930 extension cable and a 330980 Proximitor sensor.

Features

• Rugged Stainless Steel Armor (AISI 302): Integrated protective sleeving safeguards the delicate FEP coaxial cable from abrasion and impact.
• Fully Threaded Case Option (00-10): Designed with 0.0 inches of unthreaded length and a 1.0-inch total case length for maximum physical installation versatility in tight spaces.
• 1.0 Meter Lead Cable (Option 10): Provides a practical 1.0 m (39 in) standard FEP-insulated coaxial cable suited for direct cabinet transitions or proximity junctions.
• Miniature ClickLoc Connector (Option 02): Space-saving, low-profile gold-plated brass coaxial connection that ensures high-signal integrity without the added bulk of a connector protector.
• Hazardous Area Certified (Option 05): Factory-equipped with global agency certificates (ATEX, IECEx, cNRTLus) for installation in Class I, Division 1 and Zone 0 explosive atmospheres.
• Polyphenylene Sulfide (PPS) Tip: Molded high-durability polymer tip resists chemical degradation, moisture infiltration, and high-pH solutions.

Applications

• Radial vibration and axial position monitoring on high-speed aeroderivative gas turbines.
• Non-contact displacement tracking on small-bore centrifugal compressors and auxiliary machinery.
• Sensing applications with constrained mounting areas, counterbores, or offset target locations.
• Harsh industrial environments requiring mechanical armoring for cable protection.

Installation Guidelines

• Case Torque Limit: Ensure installation torque for the 1/4-28 thread does not exceed 5.1 N-m (45 in-lb) to prevent thread binding or internal sensor damage.
• Gap Adjustment: Adjust the initial gap using a voltmeter connected to the Proximitor sensor output. Set the distance to match a target reading of approximately -9.0 Vdc (1.0 mm or 40 mils gap).
• Cable Shielding and Routing: Route the armored cable through clean areas away from power conduits. Maintain a minimum bend radius of 25.4 mm (1.0 in) throughout the run.
• Connector Connection: Hand-tighten coaxial connectors until finger-tight (do not exceed 0.56 N-m or 5 in-lb). Apply silicone self-fusing tape to seal out moisture when installed in humid or oily environments.
