Eddy-Current Probe Scaling & Rotor Dynamics Technical Characteristics

This proximity probe utilizes eddy-current technology to generate a high-frequency radio frequency (RF) signal at the tip, measuring distance to a conductive target. To achieve standard eddy-current probe scaling of 7.87 V/mm (200 mV/mil), this 1.0-meter probe must connect to a matched 3300 XL Proximitor sensor via an 8.0-meter extension cable, establishing a 9.0-meter total system length. Precise physical installation and depth adjustments are necessary to validate the gap voltage, targeting a baseline reading of -10 VDC within the center of the linear operating region. This accurate calibration allows the system to register minute fluctuations in rotor dynamics—such as shaft vibration and axial position—while maintaining high cross-talk suppression.

Frequently Asked Questions

Q: How does the armored cable option (02) affect cable routing compared to standard cables?

A: The stainless steel armor jacket provides robust mechanical protection against physical damage and abrasions. However, it requires a larger minimum bend radius and has a slightly higher overall weight, which must be factored into cable run pathways.

Q: Can this 9.4-inch case length probe be used in high-vibration bearing housings?

A: Yes. The rigid 9.4-inch stainless steel sleeve allows deep penetration into the machine housing while providing stable support. To prevent probe tip vibration or deflection, the unthreaded portion is kept at 0.0 inches to maximize structural thread contact within the mounting port.

Field Installation Guidelines

Gap Voltage Adjustment: Thread the probe into the mounting bracket until the Proximitor sensor output voltage measures approximately -10.0 VDC, corresponding to a nominal physical gap of 1.27 mm (50 mils) between the tip and the shaft.
Armor Bend Limits: Maintain a minimum bend radius of 25.4 mm (1.0 inch) for the armored section of the cable to avoid kinking or fracturing the internal coaxial core.
Locknut Torquing: Once positioned, secure the probe using a standard locknut to prevent physical movement under continuous machinery vibration.
Electrical Isolation: Ensure that the connector protector is fully installed over the coaxial junction to keep the signal isolated from machine ground and to block electromagnetic noise.
