Quick Detail

Description

The 330101-00-77-15-12-05 3300 XL 8 mm Proximity Probe is a high-precision eddy current transducer optimized for industrial automation, predictive maintenance, and vibration monitoring. It generates an output voltage directly proportional to the distance between the probe tip and the observed conductive surface, enabling accurate measurements of both static positions and dynamic vibrations. With an overall case length of 7.7 inches and a total probe length of 1.5 meters (4.9 feet), this probe is ideal for monitoring large industrial shafts, turbines, and rotors where extended reach is required.

The probe features a Miniature coaxial ClickLoc connector and FluidLoc cable, ensuring reliable signal transmission in high-vibration and lubricated environments. Operating across -52°C to +177°C (-62°F to +350°F), it maintains excellent stability, with less than 2 mV output variation per volt input change and a consistent 50 Ω output resistance. The 3/8-24 UNF probe thread and maximum thread engagement of 0.563 in ensure secure mechanical installation. Patented TipLoc and CableLoc designs provide 330 N (75 lbf) pull strength, enhancing probe-cable durability. Fully CSA, ATEX, and IECEx certified, and API 670 compliant, the 3300 XL 8 mm probe supports full interchangeability with other 3300 series probes, extension cables, and Proximitor sensors, reducing maintenance complexity.

Applications

Application 1: Large Steam Turbine Rotor Monitoring

Monitors rotor displacement and vibration with micron-level precision in large steam turbines, improving preventive maintenance scheduling and minimizing unscheduled downtime.

Application 2: Industrial Pump Shaft Alignment

Detects misalignment and axial displacement in centrifugal and axial pumps, enabling enhanced operational efficiency and prolonged pump life.

Application 3: Compressor Speed and Keyphasor Feedback

Provides accurate Keyphasor reference and rotational speed measurements for compressors, supporting automated control systems and protective interlocks.

Application 4: Heavy-Duty Gearbox Vibration Monitoring

Captures gear and shaft vibration signals in high-torque industrial gearboxes, allowing early detection of wear, imbalance, or misalignment before failure occurs.

Application 5: Lubricated Machinery and Fluid Environments

The FluidLoc cable option prevents oil ingress, ensuring stable signal output and accurate vibration or displacement readings in lubricated bearings and wet industrial machinery.
