Eddy-Current Probe Scaling & Gap Voltage Validation

This 11 mm proximity probe relies on eddy-current physics 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 physical center of the linear calibration range. 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: Can this 330704 probe be connected directly to an 8 mm 3300 XL Proximitor?

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 calibration failure and invalid displacement readings.

Q: What is the purpose of the CN suffix in the product part number?

A: The CN suffix denotes country-specific agency approvals for China. This ensures that the probe meets local regulatory requirements for explosion-proof and intrinsic safety standards in industrial installations.

Field Installation Guidelines

Mounting and Torque: Thread the probe into the mounting bracket or sleeve. Do not exceed a tightening torque of 22.6 N-m (200 in-lb) for the UNF threads to prevent damaging the internal components.
Adjusting the Gap Voltage: Slowly rotate the probe toward the shaft target while monitoring the Proximitor sensor output voltage. Secure the probe locknut when the voltage matches the target offset of -10.0 VDC.
Connector Insulation: Keep the coaxial ClickLoc terminal dry and clean during connection. Ensure the integrated connector protector covers the interface completely to isolate the shield from the machine ground casing.
