Bently Nevada 330910-00-11-10-02-05 3300 NSv Proximity Probes

Description

330910-00-11-10-02-05: 3300 NSv proximity probe, M10x1 metric thread, Option 00 unthreaded length of 0 mm, Option 11 overall case length of 110 mm, Option 10 total length of 1.0 m, Option 02 miniature coaxial ClickLoc connector on standard cable, and Option 05 Multiple Approvals.

This configuration incorporates a rugged, flexible stainless steel armor sleeve over the 1.0 meter coaxial cable, protecting the assembly against mechanical wear, cutting, and abrasion. Operating on eddy-current measurement principles, this proximity probe provides non-contact shaft vibration and axial position measurements in applications with tight clearances. It is used on fluid-filmed bearing machines and high-density installations such as centrifugal air compressors or process gas machinery where space, counterbore, or target size constraints limit the use of larger standard transducers.

Features

• Metric Armor Interface: Features an M10x1 metric threaded body integrated with a flexible AISI 302 stainless steel armor sleeve over the probe cable.
• Fully Threaded Case: Option 00 provides a 0 mm unthreaded section, ensuring full thread engagement for secure mounting.
• Extended Case Reach: Option 11 specifies a 110 mm case length, facilitating deep-set installation in heavy machine casings.
• Standard ClickLoc Connection: Option 02 provides a gold-plated miniature coaxial ClickLoc connector on standard FEP-insulated cable.
• Explosive Area Approval: Option 05 supplies hazardous area approvals from major agencies, enabling installation in intrinsically safe environments.

Applications

• Radial vibration and axial position monitoring on centrifugal air and refrigeration compressors.
• Process gas compressor shaft displacement measurements.
• Vibration monitoring on machinery with limited target geometry or tight counterbore areas.
• Non-contact measurements on small-diameter shafts down to 20 mm.
• High-speed industrial rotating machinery protection systems.

Installation Guidelines

• Gapping: Set the probe gap to 1.0 mm (40 mils) using the Proximitor Sensor DC output voltage to ensure the sensor operates in the middle of its linear range.
• Tightening Torque: Secure the M10x1 threaded body into the machine housing with a recommended torque of 11.3 N m (100 in-lb) and do not exceed the maximum rated limit of 33.9 N m (300 in-lb).
• Routing and Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) along the armored cable routing path to prevent signal degradation or structural damage.
• Connector Care: Ensure ClickLoc connectors remain clean and dry. Keep them free of grease, moisture, and chemical solvents during installation.

Compliance and Certifications

• Hazardous Area Ratings: Intrinsically Safe (Ex ia IIC T5...T1 Ga) and Non-Sparking/Non-Incendive (Ex nA/ec IIC T5...T1 Gc) when connected to certified barriers per Bently Nevada drawings 141092 or 140979.
• Electromagnetic Compatibility: CE Mark compliant with European Directives 2014/30/EU (EN 61000-6-2 and EN 61000-6-4).
• Environmental Safety: RoHS Directive 2011/65/EU and China RoHS EFUP 15-year designation.
• Functional Safety: Certified up to SIL 2 (HFT=0) and SIL 3 (HFT=1) when configured in safety instrumented systems.
