Eddy-Current Probe Scaling & Gap Voltage Validation

This 11 mm probe operates via eddy-current physics to generate a localized radio frequency (RF) field at the sensor tip. To maintain proper eddy-current probe scaling of 3.94 V/mm (100 mV/mil) typically associated with the 11 mm series, this 1.0-meter probe must connect to its matched 3300 XL 11 mm Proximitor sensor through a compatible extension cable, establishing a completed 5.0-meter or 9.0-meter electrical loop. Mechanical adjustment during installation is required to validate the gap voltage, targeting a baseline reading of -10 VDC at the physical center of the linear calibration range. This voltage stabilization enables the monitor rack to track dynamic rotor dynamics and shaft displacement while minimizing signal cross-talk suppression between adjacent probe assemblies.

Frequently Asked Questions

Q: Why does the 11 mm probe have a different scaling factor compared to the standard 8 mm probe?

A: The larger 11.0 mm tip diameter generates a wider RF field, allowing for a broader linear range (typically 4.0 mm or 160 mils) than the 8 mm probe. Consequently, the linear scale factor decreases to 3.94 V/mm (100 mV/mil) to cover the wider physical gap range.

Q: Can standard 8 mm cables and Proximitors be used with this 11 mm probe?

A: No. The 11 mm probe has distinct physical and electrical properties. Using it with 8 mm Proximitors or mismatched extension cables will compromise the system impedance, leading to massive calibration errors and incorrect vibration readings.

Field Installation Guidelines

Mounting and Torque: Thread the probe into the mounting sleeve. Do not exceed a tightening torque of 22.6 N-m (200 in-lb) for the 1/2-20 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.
