Quick Detail

Description

The 330705-02-18-90-02-00 3300 XL 11 mm Reverse Mount Probe is a high-precision transducer designed for advanced industrial automation systems, delivering reliable non-contacting vibration and displacement measurements on fluid film bearing machinery. Featuring an 11 mm probe tip, this reverse mount probe provides an extended linear range compared to standard 3300 XL 8 mm probes, ensuring precise axial, radial, and phase measurement capabilities. Equipped with a 9.0-meter (29.5-foot) triaxial FEP-insulated extension cable and optional flexible AISI 302 stainless steel armor, the probe supports harsh industrial environments with operating temperatures from -52°C to +177°C (-62°F to +351°F). The miniature ClickLoc coaxial connector with gold-plated contacts guarantees secure connections and high signal integrity, while the patented TipLoc and CableLoc designs provide robust probe tip bonding and 330 N (75 lb) cable pull strength. With 3/8-24 UNF threads and compatibility with various armored or unarmored probe case configurations, the 3300 XL 11 mm Reverse Mount Probe integrates seamlessly into monitoring systems such as the 3500, delivering accurate Keyphasor, tachometer, zero-speed, rod position, and differential expansion measurements. Its durable construction, including high-strength materials and optional FluidLoc cable sealing, ensures reliable operation in demanding automation environments, while reverse mount configuration enables installation in restricted or confined spaces, providing flexibility for modern industrial setups.

Applications

Axial (Thrust) Position Monitoring

Used in large steam or gas turbines, the reverse mount configuration allows precise axial position measurement, supporting ±50 µm accuracy in high-speed applications.

Differential Expansion Measurement

Enables monitoring of ramp differential expansion in rotating machinery, providing early detection of thermal deformation for predictive maintenance.

Rod Position Monitoring in Reciprocating Compressors

The 3300 XL 11 mm probe measures rod position or rod drop with high linearity over the 11 mm range, ensuring accurate detection of misalignment or wear.

Tachometer and Zero-Speed Sensing

Generates precise phase and speed signals for machinery control systems, enabling accurate rotation speed measurement from 0 to 10,000 RPM.

Phase Reference (Keyphasor) Signal Generation

Provides high-fidelity Keyphasor signals for vibration analysis, improving the reliability of condition-based monitoring systems by over 15% compared to older 7200-series systems.

Specifications

Competitive Advantage

Extended Linear Measurement Range

The 11 mm tip provides longer linear displacement measurement, reducing probe saturation and improving data resolution by 20% over 8 mm probes.

High-Temperature and Harsh Environment Compatibility

Operating range of -52°C to +177°C, combined with optional armored FEP cable, ensures stable performance in extreme industrial conditions.

Robust Mechanical Design

Patented TipLoc and CableLoc designs provide 330 N cable pull strength and secure probe tip bonding, minimizing mechanical failures during vibration exposure.

Reliable Signal Integrity

Gold-plated ClickLoc coaxial connectors maintain high-quality output with less than 2 mV variation per volt of input change, ensuring consistent readings in automation systems.

Flexible Installation Options

Reverse mount configuration with 3/8-24 UNF threads allows integration in confined or obstructed machine areas, enhancing versatility for retrofits and new installations.
