Quick Detail

Description

The 3300 XL 8 mm Proximity Probe (330101-00-77-15-02-05) is a high-precision eddy current transducer engineered for industrial automation, predictive maintenance, and real-time monitoring of rotating machinery. It generates an output voltage proportional to the distance between the probe tip and a conductive surface, enabling accurate measurements of both static position and dynamic vibration. This makes it ideal for fluid-film bearings, turbines, compressors, and pumps where reliability and precision are critical.

This version features a 7.7-inch overall case length with 0-inch unthreaded length, accommodating installations where a longer probe body is required. Its 3/8-24 UNF threaded case ensures secure mounting, while the 1.5-meter (4.9-foot) miniature coaxial ClickLoc cable allows seamless integration with standard 3300 XL Proximitor systems. The probe is certified for use in hazardous environments under CSA, ATEX, and IECEx approvals and operates reliably in extreme temperatures from -52°C to +177°C (-62°F to +350°F).

Key technical specifications include a 2 mm (80 mils) linear range, 50 Ω output resistance, supply sensitivity under 2 mV per volt, and 69.9 pF/m extension cable capacitance, ensuring stable signal transmission. The patented TipLoc design strengthens the bond between probe tip and body, while CableLoc technology provides 330 N (75 lbf) pull strength, securing the cable against mechanical stress. Optional FluidLoc cables prevent oil or liquid ingress, ensuring probe reliability and reducing maintenance needs. Fully backward-compatible with 3300 series 5 mm and 8 mm probes, the system enables easy upgrades without recalibration.

Applications

1. Radial Shaft Vibration Monitoring
Measures radial displacement with precision up to 2 mm, enabling detection of imbalance, bearing wear, or misalignment in turbines and compressors.

2. Axial Position Tracking
Monitors axial (thrust) movement in fluid-film bearings to prevent overload and maintain optimal pump and turbine performance.

3. Keyphasor Signal Generation
Provides accurate phase reference for vibration analysis and rotor balancing, critical for predictive maintenance programs.

4. Hazardous Area Operation
Certified for CSA, ATEX, and IECEx, allowing safe deployment in oil, gas, and chemical environments.

5. Compact Installation in Restricted Spaces
The probe’s 7.7-inch length accommodates tight mounting areas while maintaining high measurement fidelity.

Specifications

Competitive Advantage

1. Extreme Temperature Reliability
Operates from -52°C to +177°C, providing uninterrupted performance in harsh industrial environments.

2. High Mechanical Durability
TipLoc and CableLoc designs provide 330 N pull strength, securing the probe cable and preventing detachment.

3. Precision and Signal Stability
Less than 2 mV per volt supply sensitivity and a 2 mm linear range ensure accurate vibration and position measurements.

4. Backward Compatibility
Compatible with 3300 series 5 mm and 8 mm probes, allowing seamless integration and upgrades without bench calibration.

5. Liquid Ingress Protection
Optional FluidLoc cables prevent oil or process fluids from entering the probe, protecting the probe and machinery while minimizing downtime.
