Bently Nevada 330102-00-14-10-02-00 3300 XL 8mm Proximity Probe

Description

Engineered for heavy-duty machinery asset monitoring, the Bently Nevada 330102-00-14-10-02-00 3300 XL 8mm Proximity Probe delivers high-precision, non-contact dynamic displacement and static shaft position measurements. This probe is a critical sensing element designed for integration into API 670-compliant machinery protection systems, offering exceptional stability, linearity, and thermal performance in demanding industrial environments.

Features

• Utilizes reliable eddy current technology for non-contact shaft displacement and vibration measurement.
• Equipped with a miniature coaxial ClickLoc connector to prevent accidental disconnection in high-vibration environments.
• Features a standard-type cable configuration engineered to resist degradation from common industrial lubricants and solvents.
• Designed for direct integration with 3300 XL Series Proximitor Sensors without requiring special calibration adjustments.
• Constructed with a robust, unarmored case profile optimized for clean conduit routing.

Applications

• Steam, gas, and hydro turbine radial vibration and thrust position tracking.
• Centrifugal and reciprocating compressor shaft dynamics diagnostics.
• Industrial gearbox shaft relative movement and thermal growth monitoring.
• High-speed pump shaft runout and oil film thickness measurements.

Alternative Models & Compatibility

The 330102 series is highly compatible across the 3300 XL product family. Always ensure that the combined length of your probe and extension cable equals the exact calibration length required by the Proximitor Sensor (typically 5.0 meters or 9.0 meters total system length). Mixing a 1.0-meter probe with an incompatible extension cable or a non-matching Proximitor model will cause severe scale factor errors, degrading accuracy beyond API 670 limits.

Application Pitfalls & Engineering Notes

When deploying the probe inside tight machine housings, maintain a minimum side clearance of at least three times the probe tip diameter (24 mm) from any surrounding structural metals. Failure to do so leads to "side-sensing" or "cross-talk," which artificially biases the DC gap voltage and disrupts accurate dynamic displacement measurement of the shaft target material.

Commissioning & Wiring Tips

During commissioning, use a calibrated digital multimeter to monitor the DC gap voltage at the Proximitor Sensor terminals. Adjust the probe depth until the output reads approximately -10.0 VDC, indicating that the probe is physically positioned at the center of its 80-mil (2.0 mm) linear operating range. Always apply a ClickLoc connector protection kit to seal connection points from oil contamination in the wet-sump areas of turbines or compressors.
