Quick Detail

Description

The 3300 XL 8 mm Proximity Probe (330101-00-84-20-02-05) is a high-precision eddy current transducer designed for advanced industrial automation, rotating machinery monitoring, and predictive maintenance applications. It provides a reliable output voltage directly proportional to the distance between the probe tip and conductive surfaces, enabling both static (position) and dynamic (vibration) measurements. This probe is specifically engineered for fluid-film bearing machines, compressors, turbines, and high-speed rotating equipment, delivering accurate data for shaft vibration, Keyphasor phase reference, speed detection, and axial position monitoring.

Featuring a total cable length of 2.0 meters (6.6 feet) and an overall case length of 8.4 inches, the 3300 XL 8 mm probe is ideal for tight installation spaces, including side-view, reverse mount, and counter bore applications. Its 3/8-24 UNF threaded housing ensures secure and repeatable installation. Operating reliably across a temperature range of -52°C to +177°C (-62°F to +350°F), it meets CSA, ATEX, and IECEx approvals, making it suitable for hazardous and high-demand industrial environments. With a linear range of 2 mm (80 mils), output resistance of 50 Ω, minimal supply sensitivity (<2 mV per volt), and extension cable capacitance of 69.9 pF/m, the probe ensures consistent, high-fidelity signal transmission under varying conditions.

Mechanically, the probe integrates TipLoc molding for enhanced bonding between the probe tip and body, and CableLoc technology, providing 330 N (75 lbf) pull strength for secure cable attachment. Optional FluidLoc cabling prevents oil or process fluids from entering the cable, maintaining signal integrity and extending equipment lifespan. Fully backward-compatible with 3300 series 5 mm and 8 mm probes and extension cables, the 3300 XL 8 mm probe supports cost-effective system upgrades without recalibration. Its combination of precision, durability, environmental resilience, and compatibility makes it an essential component for industrial automation and machine condition monitoring systems.

Applications

1. Radial Shaft Vibration Monitoring
Measures radial vibrations on shafts up to 51 mm (2 in). The 2 mm linear range enables early detection of imbalance, misalignment, or bearing wear for predictive maintenance.

2. Axial (Thrust) Position Detection
Monitors axial displacement of shafts to prevent mechanical overload and ensure optimal bearing operation in compressors, pumps, and turbines.

3. Keyphasor Phase Reference Generation
Generates accurate phase reference signals for high-speed rotating machinery, supporting vibration analysis, speed measurement, and synchronous monitoring.

4. Operation in Hazardous Zones
CSA, ATEX, and IECEx approvals allow safe deployment in explosive or high-risk environments without compromising performance or reliability.

5. Compact Installation Adaptability
8.4-inch probe case with 3/8-24 UNF thread supports side-view or reverse mount installations, enabling precise measurements in space-constrained equipment.

Specifications

Competitive Advantage

1. Extreme Temperature and Environment Resilience
