Description

Option 00 (0.0 in unthreaded length), Option 16 (1.6 in overall case length), Option 10 (1.0 m total length), and Option 01 (miniature ClickLoc connector with connector protector) define the configuration of the 330908-00-16-10-01-05 3300 NSv Proximity Probe. This non-armored probe features a standard 3/8-24 UNF-2A thread body and is optimized for industrial rotating machinery with tight clearances or small shaft targets where standard 5 mm or 8 mm systems cannot be installed. By utilizing standard FEP-insulated coaxial cable without an outer stainless steel armor, this probe minimizes space requirements in compact or congested machine housings. This probe pairs with a 3300 XL NSv Proximitor Sensor and a 330930 extension cable to form a complete eddy-current displacement measurement system. The integrated fluorosilicone connector protector shields the ClickLoc connection joint from moisture, turbine oil, and other contaminants. Option 05 hazardous area certification provides global standard compliance for hazardous environments, enabling safe, long-term operation on high-speed centrifugal compressors, refrigeration compressors, and small-bore aeroderivative turbines.

Features

• 3/8-24 UNF-2A thread configuration without stainless steel armor reduces outer diameter footprint.
• 0.0 in unthreaded length permits full thread engagement across the entire 1.6 in case length.
• 1.0 m total probe lead length offers compact and direct routing inside machine casings.
• Fluorosilicone connector protector pre-installed on the miniature coaxial ClickLoc connector seals out environmental contaminants.
• Option 05 agency approval package simplifies multi-jurisdiction compliance across ATEX, IECEx, and North American hazardous areas.

Applications

• Radial vibration and axial position monitoring on centrifugal air compressors.
• Shaft displacement measurement on small-bore high-speed refrigeration compressors.
• Speed and phase reference (Keyphasor) detection on aeroderivative gas turbines.
• Tight clearance monitoring on fluid-filmed bearing machines with target diameters smaller than 51 mm.

Installation Guidelines

• Standard mount 3/8-24 UNF-2A threads are supplied with a 9/16 inch lock nut and 5/16 wrench flats; tighten within recommended torque limits.
• Ensure the target surface is composed of AISI 4140 steel or matches the specific calibration profile of your 3300 XL NSv Proximitor Sensor.
• Avoid installing standard FEP cable runs near sharp edges; route through protective conduit or secure using cable clamps to prevent mechanical abrasion.
• The ClickLoc coaxial connector should be mated by hand and protected with the pre-fitted fluorosilicone connector sleeve to ensure fluid-tight sealing.
• Avoid exposing the Viton pressure seal to temperatures below -34 degC (-30 degF) for extended durations to maintain structural integrity.
