Bently Nevada 330902-00-15-10-02-05 3300 NSv Proximity Probe

Description

Option 00 (0.0 inches unthreaded length), Option 15 (1.5 inches overall case length), and Option 02 (miniature coaxial ClickLoc connector with standard cable) define the exact configuration of this 330902-00-15-10-02-05 3300 NSv Proximity Probe. This non-contact transducer is optimized for eddy-current displacement measurements in tight clearances or where target geometry is constrained, such as in small-bore rotating machinery or aeroderivative gas turbines. The built-in stainless steel armor provides robust mechanical protection against physical damage and abrasive environments, shielding the internal 75-ohm coaxial cable without sacrificing flexibility.

Unlike standard unarmored configurations (such as model 330901) or options utilizing a connector protector (such as Option 01), this specific probe relies on standard stainless steel armor and a bare ClickLoc connector for direct-insertion setups. Additionally, the inclusion of Option 05 hazardous area certification extends its safe deployment into environments requiring multiple global agency approvals, including CSA, ATEX, and IECEx standards.

Features

• Option 00 unthreaded design provides a fully threaded 1/4-28 UNF case for precise gap calibration inside standard brackets.
• Option 15 case length provides a 1.5 inch overall threaded envelope suitable for shallow mounting depths.
• Integrated stainless steel armor (model 330902) shields the coaxial cable from harsh physical hazards, pinching, and abrasion.
• Option 10 length defines a 1.0 meter (39 inches) total probe length, minimizing intermediate cable connections inside the machine housing.
• Option 02 miniature coaxial ClickLoc connector provides a secure, low-loss electrical connection to standard extension cables.
• Option 05 agency approval package certifies the probe for intrinsic safety and non-incendive environments under multiple international bodies.

Applications

The 3300 NSv proximity system is designed for machinery with limited target size or tight physical clearances. Typical industrial applications include:

• Radial vibration and axial position measurements on small-diameter shafts under 30 mm (1.2 inches).
• Vibration monitoring on aeroderivative gas turbines with highly congested internal spacing.
• Thrust and radial displacement tracking in high-speed compressors and small-bore centrifugal pumps.
• General industrial rotating equipment requiring non-contact displacement monitoring in hazardous zones.

Installation Guidelines

• Probe Thread Engagement: Maximum recommended thread engagement length for 1/4-28 UNF probe cases is 0.375 inches to avoid mechanical binding.
• Case Torque: Tighten the probe case to a recommended mounting torque of 5.1 N-m (45 in-lb), up to a maximum rating of 7.3 N-m (65 in-lb).
• Cable Bend Radius: Maintain a minimum physical bend radius of 25.4 mm (1.0 inch) for both armored and unarmored probe leads to prevent coaxial shielding degradation.
• Connector Protection: If the connection between the probe and extension cable is exposed to liquids or moisture, use silicone self-fusing tape or a connector protector kit to maintain signal integrity. Do not use silicone tape inside the machine casing.
