Eddy-Current Probe Scaling & Gap Voltage Validation

This 11 mm probe relies on eddy-current technology to generate a high-frequency electromagnetic field that measures the distance between the probe tip and a conductive target. To maintain standard eddy-current probe scaling of 3.94 V/mm (100 mV/mil), the probe must be connected via a matched 11 mm extension cable to a calibrated 3300 XL 11 mm Proximitor. Accurate mechanical adjustment during commissioning is necessary to achieve proper gap voltage validation, aiming for a target value of -10 VDC at the center of the linear calibration envelope. Correct physical gapping ensures optimal tracking of rotor dynamics and prevents measurement distortion caused by signal cross-talk suppression between adjacent sensor installations.

Frequently Asked Questions

Q: What is the primary functional purpose of the ClickLoc connector protector supplied with Option 01?

A: The connector protector physically seals the connection between the probe cable and the extension cable. It prevents moisture ingress, contamination by lubricating oils, and guards against capacitive coupling and leakage currents that degrade the RF signal.

Q: Can this 11 mm probe be calibrated with standard 8 mm Proximitor sensors?

A: No. The 11 mm probe tip has distinct electrical impedance properties and a wider sensing field than an 8 mm probe. Interfacing this probe with an 8 mm Proximitor will cause severe impedance mismatching, leading to system calibration failure and invalid displacement readings.

Field Installation Guidelines

Mechanical Mounting and Torque: Thread the M14 x 1.5 probe body into the mounting bracket or sleeve. Do not exceed a maximum tightening torque of 22.6 N-m (200 in-lb) to prevent shearing or crushing the internal sensor elements.
Setting the Physical Gap: Connect a digital voltmeter to the Proximitor "OUT" and "COM" terminals. Rotate the probe until the voltmeter registers the target gap voltage of -10.0 VDC (±0.2 VDC) relative to the shaft target before locking the jam nuts.
Cable Handling Cautions: Observe the minimum bend radius of 25.4 mm (1.0 inch) for standard unarmored probe cables. Sharp bends or kinks will damage the coaxial shielding, resulting in signal noise and calibration drift.
