Eddy-Current Probe Scaling and Gap Voltage Validation

The 330104-10-20-10-02-CN proximity probe generates a high-frequency radio frequency (RF) signal at its 8 mm tip to implement accurate eddy-current probe scaling against a conductive metal shaft. When integrated into a complete transducer loop with a 3300 XL Proximitor Sensor, physical gap changes are converted into a linear voltage output. Field verification necessitates precise gap voltage validation to anchor the sensor within its linear calibration range. Installation technicians must fine-tune the mechanical position until the static output potential registers the designated -10 VDC targets, identifying the midpoint of the calibrated measuring field. This proper baseline ensures the loop can track dynamic rotor dynamics without waveform clipping, while the shielded coaxial design guarantees high cross-talk suppression between close-proximity radial and axial sensors.

Frequently Asked Questions

Q: How does the length of the 10 feet cable affect compatibility with the external Proximitor sensor?

A: Transducer loops require a specific total electrical length (typically 5.0 meters or 9.0 meters). A probe with a 10 feet (approximately 3.0 meters) cable must be matched with a specific extension cable length and a corresponding Proximitor sensor tuned for that total system length to prevent errors in eddy-current probe scaling.

Q: What physical failure occurs if the ClickLoc coaxial connector shell makes contact with the machine frame?

A: Contact between the connector shell and the machine frame creates a parallel ground loop path. This injects electrical noise into the measurement circuit, overriding the native cross-talk suppression and distorting the dynamic vibration readings.

Field Installation Guidelines

Mechanical Threading and Clearance: Inspect the M10 x 1 threaded mounting bore. Hand-thread the probe case to prevent cross-threading, ensuring the 1.0 inch unthreaded portion aligns with the mounting template without causing the tip to strike the shaft target.
Gap Voltage Calibration: Energize the proximity transducer loop and bridge a digital voltmeter across the Proximitor signal terminals. Rotate the probe body slowly until the static voltage stabilizes at -10 VDC before locking the position.
Locknut Mechanical Torque: Secure the locknut against the entry flange to stabilize the hardware. Monitor the voltmeter continuously during torque application to ensure the mechanical tension does not shift the probe away from the -10 VDC targets.
Coaxial Path Routing: Guide the 10 feet coaxial cable through grounded metal conduit. The pathway must maintain a minimum static bend radius of 25.4 mm (1.0 inch) to preserve the mechanical and electrical integrity of the internal shield layers.
