Bently Nevada 330901-00-09-10-02-05 3300 NSv Proximity Probes

Description

Option 00 (0.0 in unthreaded length) and Option 09 (0.9 in case length) specify this standard 1/4-28 UNF unarmored probe configuration — 330901-00-09-10-02-05. This 3300 NSv proximity probe is part of the 3300 XL NSv Proximity Transducer System, used for non-contact displacement measurements in machinery with limited target geometry and tight clearances. With a total length of 1.0 meter (Option 10) and a standard cable without connector protector terminating in a miniature coaxial ClickLoc connector (Option 02), this configuration is suited for compact mounting footprints where side-view clearance is restricted.

The 3300 NSv system features increased chemical resistance compared to previous generations, making it suitable for process compressor installations. Sibling configurations with other options may include stainless steel armor (such as the 330902 base model) or FluidLoc cables for sealing against media leakage, whereas this unarmored standard-cable SKU is selected for direct dry well or internal mounting scenarios with multiple agency approvals (Option 05).

Features

• Thread Configuration: Standard 1/4-28 UNF thread with 0.0 in unthreaded length and 0.9 in overall case length.
• Cable Type: Unarmored standard coaxial probe cable with 1.0 m total length.
• ClickLoc Connector: Gold-plated brass miniature male ClickLoc coaxial connector without connector protector.
• Tip Design: TipLoc molding provides a chemical-resistant bond between the polyphenylene sulfide (PPS) tip and the AISI 304 stainless steel case.
• Secure Cable Attachment: CableLoc mechanism provides 220 N (50 lb) of pull strength between the probe lead and the probe tip.
• Multiple Approvals: Certified under Option 05 for use in hazardous areas with multiple international certifications.

Applications

• Axial position and radial vibration measurements on small-bore machinery.
• Vibration monitoring on aeroderivative gas turbines.
• Displacement measurement in high-speed industrial equipment with limited target geometry.
• Centrifugal process compressors where narrow side-view clearance is required.

Installation Guidelines

• Target Size: Standard calibration is for an AISI 4140 steel flat target with a minimum recommended diameter of 13 mm (0.5 in). Targets smaller than 13 mm may affect the scale factor.
• Clearance: Maintain a minimum separation of 25 mm (1.0 in) for axial position or 23 mm (0.9 in) for radial vibration measurements to prevent electromagnetic cross-talk between probe tips.
• Connector Security: Ensure ClickLoc coaxial connectors are fully locked into position. Do not use connector protectors inside the machine casing.
• Bending Radius: Avoid bending the coaxial cable with a radius less than 25.4 mm (1.0 in) to prevent transmission loss.
• Pressure Seal Warning: Exposing the probe to temperatures below -34 degC (-30 degF) for sustained periods can degrade the Viton pressure seal.
