Quick Detail

Description

The 3300 XL 8 mm Proximity Probe (330101-00-75-20-02-05) is a precision eddy current sensor designed for advanced industrial automation and condition monitoring applications. Engineered to deliver highly accurate measurement of both static position and dynamic vibration, the 3300 XL 8 mm probe converts the distance between the probe tip and conductive target into a proportional output voltage, providing reliable monitoring for rotating machinery, compressors, turbines, and fluid-film bearing systems.

This probe features a total length of 2.0 meters (6.6 feet), with a 7.5-inch overall case length and 3/8-24 UNF threaded housing, making it suitable for secure installation in restricted spaces. It operates across a wide temperature range from -52°C to +177°C (-62°F to +350°F) and supports CSA, ATEX, and IECEx certifications, allowing safe use in hazardous environments. The 3300 XL 8 mm probe delivers a linear range of 2 mm (80 mils) with minimal supply sensitivity (less than 2 mV change per volt) and an output resistance of 50 Ω, ensuring stable signal quality under fluctuating electrical conditions.

Mechanically robust, the probe incorporates patented TipLoc molding to strengthen the bond between probe tip and body, and CableLoc technology, which provides 330 N (75 lbf) pull strength to secure the probe cable. Optional FluidLoc cabling prevents leakage of oil or process fluids, maintaining both signal integrity and machinery safety. Fully backward-compatible with non-XL 3300 series 5 mm and 8 mm probes and extension cables, the 3300 XL 8 mm probe simplifies system upgrades while eliminating the need for recalibration or matching of individual components. This combination of accuracy, durability, and environmental resilience makes it a top choice for high-performance industrial automation applications.

Applications

1. Radial Vibration Monitoring
Provides precise measurement of radial vibrations in shafts up to 51 mm (2 in) diameter, helping detect imbalance, misalignment, or bearing wear. Linear range: 2 mm ensures high-resolution diagnostics.

2. Axial (Thrust) Position Measurement
Monitors axial shaft displacement on fluid-film bearings and turbines, preventing excessive thrust loads and protecting critical machinery components.

3. Keyphasor Signal Generation
Generates reliable phase reference signals for high-speed machinery, supporting vibration analysis, speed monitoring, and predictive maintenance programs.

4. Hazardous Environment Operation
Certified to CSA, ATEX, and IECEx standards, enabling safe deployment in chemical plants, refineries, and offshore facilities while maintaining accurate signal measurement.

5. Limited Space Installations
Designed for tight or constrained spaces, including reverse mount, side-view, or counter bore applications, where larger probes cannot fit without compromising performance.

Specifications

Competitive Advantage

1. High-Temperature and Harsh Environment Tolerance
Operates reliably from -52°C to +177°C (-62°F to +350°F), with CSA, ATEX, and IECEx approvals for hazardous industrial settings.

2. Mechanically Robust Design
Patented TipLoc and CableLoc technologies provide secure probe tip-to-body attachment and 330 N pull-strength cable connections, reducing maintenance and downtime.

3. Accurate and Stable Measurement
Linear range of 2 mm and less than 2 mV supply sensitivity guarantee precise detection of both static and dynamic shaft displacement.

4. Flexible System Compatibility
Backward-compatible with 3300 series 5 mm and 8 mm probes and extension cables, enabling seamless system upgrades without the need for recalibration.

5. Protection Against Fluid Contamination
Optional FluidLoc cable prevents oil and process fluids from leaking through the probe cable, safeguarding signal integrity and equipment safety.
