Eddy-Current Probe Scaling & Gap Voltage Validation

This transducer operates via eddy-current physics to generate a dynamic electromagnetic field at the probe tip. To achieve standard eddy-current probe scaling of 7.87 V/mm (200 mV/mil), the probe must be paired with a matched 3300 XL Proximitor sensor and a 3300 XL extension cable to form a total system length of either 5.0 meters or 9.0 meters. Proper physical installation and depth adjustment are required to maintain the gap voltage validation within the -10 VDC target range, which represents the center of the linear calibration envelope. This baseline voltage accuracy enables the host TSI rack to measure static and dynamic shaft positions, providing precise data on rotor dynamics while maintaining high cross-talk suppression between adjacent probe lines.

Frequently Asked Questions

Q: Can this 1.0-meter probe be directly connected to a Proximitor sensor without an extension cable?

A: No. The probe must be connected through a matched extension cable (typically an 8.0-meter extension cable to form a 9.0-meter system) to match the calibration impedance of the Proximitor. Direct connection will cause severe impedance mismatching and disable signal linearization.

Q: What is the physical assembly function of the ClickLoc connector with the connector protector?

A: The ClickLoc connector provides a secure coaxial lock that resists vibration-induced loosening. The connector protector physically insulates and seals the connection joint, preventing moisture ingress and eliminating ground loop risks caused by contact with the machine casing.

Field Installation Guidelines

Gap Voltage Adjustment: Mount the probe using brackets and adjust the physical position relative to the target shaft until the Proximitor sensor output reads -10.0 VDC (typically representing a physical gap of approximately 1.27 mm or 50 mils).
Connector Torque Limits: Connect the ClickLoc terminals hand-tight. Do not use standard pliers, as over-tightening can crush the miniature coaxial core and permanently degrade signal transmission.
Minimum Bend Radius: Ensure the coaxial cable lead maintains a minimum bend radius of 25.4 mm (1.0 inch) to prevent damage to the internal dielectric layers.
Isolation Requirements: The coaxial connector junction must be fully insulated from machine ground using the pre-installed connector protector to avoid interference from parasitic current loops.
