Description

The 330105-02-12-90-02-00 is a highly accurate eddy current proximity probe from the Bently Nevada 3300 XL 8 mm series, specifically built with a fixed 0.2-inch unthreaded length and a 1.2-inch overall case length utilizing a 3/8-24 UNF threaded body. This precision-engineered device serves as a primary sensor within a machinery protection framework, operating to monitor the precise physical gap between the probe tip and a rotating or reciprocating shaft target. It continuously translates shaft displacement or dynamic mechanical vibration data into proportional high-frequency electrical signals. These signals are transmitted to an external Proximitor sensor for comprehensive asset condition evaluation, enabling critical predictive maintenance across large-scale industrial automation plants.

Features

• Standard backward compatibility and full interchangeability with standard, non-XL 3300 series 5 mm and 8 mm transducer components.
• Optimized reverse mount housing structure featuring a precise 3/8-24 UNF thread pitch.
• FluidLoc cable technology configuration blocks internal line leakage and oil migration through the inner wire core.
• Pre-terminated with a robust, click-locking Miniature ClickLoc coaxial connector interface.
• Superior environmental resistance and signal stability under demanding mechanical and temperature profiles.

Applications

• Continuous radial vibration tracking and axial position tracking on industrial fluid-film bearings.
• Dynamic thrust positioning monitoring for high-speed gas/steam turbines, turbo-compressors, and process pumps.
• Phase speed reference capturing and Keyphasor timing measurements.

Installation Guidelines

• Linear Calibration Range: Ensure proper mechanical gapping prior to system commissioning. For an AISI 4140 target, typical calibration is set at a mid-scale gap of 1.27 mm (50 mils) to match the standard 200 mV/mil Proximitor sensitivity output.
• Mechanical Torque Constraints: Mount the probe casing body firmly into the protection sleeve. Avoid over-tightening past standard industrial engineering specifications for 3/8-24 UNF steel threads to prevent structural body shearing.
• Cable Strain Relief: Securely route the 9.0-metre specialized line through low-noise cable pathways or physical steel conduit lines to avoid tight kinks, pinching, or excessive electromagnetic interference exposure.
• Connector Insulation: Ensure that the ClickLoc termination points remain dry and thoroughly insulated. Use protective boots if needed to guarantee the coaxial shield does not ground out against the surrounding machine structure.
