Hardware Specifications

Rotor Dynamics and Eddy-Current Probe Scaling

Eddy-current probe scaling depends on strict mechanical-to-electrical calibration over a 7.87 V/mm (200 mV/mil) linear scale when coupled with a 3300 XL Proximitor Sensor and extension cable. During physical mounting, gap voltage validation target (-10 VDC targets at center gap) ensures the probe operates within its dynamic range. Cross-talk suppression requires maintaining spatial separation between adjacent probe tips on high-speed shaft journals to prevent field overlap and false vibration readings.

Frequently Asked Questions

Q: Can this probe be connected directly to a PLC or DCS analog input module?

A: No. The probe requires a matching 3300 XL extension cable and 3300 XL Proximitor Sensor to condition the high-frequency eddy-current impedance change into a voltage output signal.

Q: What is the primary purpose of the ClickLoc connector design?

A: The ClickLoc miniature coaxial connector provides a positive locking mechanism that prevents physical disconnection under machinery vibration without requiring specialized torque tools.

Field Installation Guidelines

• Verify thread engagement on the M10 x 1 reverse mount port to prevent mechanical binding prior to probe insertion.
• Set physical gap distance using a multimeter connected to the Proximitor Sensor output terminals, adjusting the probe depth until reading -10 VDC (-2.5 mm physical gap equivalent).
• Maintain minimum coaxial cable bend radius of 25.4 mm (1.0 inch) during routing to prevent core conductor damage or signal attenuation.
• Insulate the miniature coaxial ClickLoc connector using self-fusing silicone tape or connector protectors to prevent grounding against local machine casing.
• Earth the overall cable shield at the monitoring rack end only to eliminate ground loop current interference on signal lines.
