Quick Detail

Description

The 330101-00-11-20-02-05 3300 XL 8 mm Proximity Probe is a high-precision eddy-current transducer engineered for advanced industrial automation and machinery monitoring. This probe converts displacement into an output voltage directly proportional to the distance between the probe tip and a conductive target, enabling accurate measurement of both static position and dynamic vibration. Featuring a compact 1.1-inch overall case length and an extended 2.0-meter total cable length, it is designed for flexible installation in constrained or complex automation systems. The miniature coaxial ClickLoc connector with 69.9 pF/m extension capacitance ensures low-noise, reliable signal transmission, while the 3/8-24 UNF threaded case with 0.563-inch maximum thread engagement provides secure mounting. Operating across a wide temperature range of -52°C to +177°C (-62°F to +350°F), this probe delivers stable performance, minimal supply sensitivity (<2 mV per volt), and a 50 Ω output resistance. Fully compliant with API 670 standards, the 3300 XL 8 mm probe supports seamless interchangeability with both XL and standard 3300 series components. Patented TipLoc and CableLoc designs enhance probe-tip bonding and cable attachment strength, providing 330 N (75 lbf) pull resistance, while the optional FluidLoc protection prevents leakage of lubricants, making it ideal for fluid-film bearing systems, vibration monitoring, speed sensing, and Keyphasor reference applications in automated and hazardous environments.

Applications

1. Dynamic Vibration Monitoring
Accurately detects vibration amplitudes as small as 2 µm in high-speed rotating machinery such as turbines, compressors, and pumps, enabling predictive maintenance.

2. Shaft Position and Alignment Control
Provides precise static measurements for radial displacement and shaft runout, maintaining alignment within ±2 mm for reliable automated operation.

3. Speed and Keyphasor Reference Signal Generation
Delivers high-fidelity signals for speed monitoring and synchronization in gas and steam turbines, supporting automation and process control.

4. API 670 Standard-Compliant Machine Monitoring
Ensures vibration and position measurements meet rigorous American Petroleum Institute standards, critical for power generation, petrochemical, and refinery applications.

5. Hazardous Industrial Environment Deployment
CSA, ATEX, and IECEx approvals allow safe operation in explosive or flammable atmospheres without compromising measurement accuracy.

Specifications

Competitive Advantage

Wide Operating Temperature: -52°C to +177°C
The 3300 XL 8 mm Proximity Probe functions reliably in extreme environments from -52°C to +177°C, making it ideal for high-heat turbines, compressors, and motors in industrial automation systems.

TipLoc and CableLoc Pull Strength: 330 N
Equipped with patented TipLoc and CableLoc designs, the probe withstands up to 330 N of pull force, ensuring the cable and probe tip remain securely mounted during high-vibration operations, reducing downtime in automated machinery.

Compatibility with XL and 3300 Series Components
The 3300 XL 8 mm Proximity Probe works seamlessly with XL and standard 3300 series probes, extension cables, and Proximitor sensors. This allows quick replacement and simplifies inventory management for industrial automation setups.

Precision Gap-to-Voltage Output: <2 mV/V
The probe maintains less than 2 mV output variation per volt input, delivering accurate gap-to-voltage measurements critical for vibration monitoring, rotor displacement tracking, and automated control feedback.
