Allen-Bradley EK-2110-30-05-1-10 Proximity Sensors

The Allen-Bradley EK-2110-30-05-1-10, also cataloged as the EK-2110-30-05-1-10 Eddy Current Displacement Probe, operates as a dedicated hardware component for non-contact shaft vibration, axial displacement, and rotor position measurement within 2100 Condition Monitoring Series platforms.

Hardware Specifications

Eddy-Current Probe Scaling & Gap Voltage Validation

The Allen-Bradley EK-2110-30-05-1-10 probe utilizes high-frequency electromagnetic field induction to maintain linear eddy-current probe scaling across API 670-aligned machinery protection architectures. Engineerd for real-time monitoring of high-speed rotor dynamics, the sensor tip generates an analog voltage output corresponding directly to dynamic shaft vibration and static target displacement. Gap voltage validation during field setup verifies proper physical standoff clearance between the probe tip and target shaft surface, ensuring reliable cross-talk suppression and signal integrity through the 1 m armored lead and 5 m extension cable assembly in contaminated industrial environments.

Frequently Asked Questions

Q: How is physical target gap voltage verified on the EK-2110-30-05-1-10 during probe installation?

A: Static probe positioning is validated by monitoring the DC gap voltage output at the connected 2100-series driver module, adjusting probe depth until the voltage reads at the designated API 670 center-scale target value (typically -10 VDC in standard probe system calibrations).

Q: What mechanical protection does the integrated armored section provide to the signal cable?

A: The 1 m integrated armored section wraps the internal coaxial lead in flexible stainless steel conduit, protecting the signal path from mechanical crushing, hot metal debris, and physical abrasion near rotating equipment.

Q: Can the EK-2110-30-05-1-10 probe be operated independently without a matching driver module?

A: No. The eddy current probe requires continuous high-frequency excitation driving current supplied by a matched 2100-series driver module to form a complete calibrated measurement circuit.

Field Installation Guidelines

1. Mount the 30 mm probe body securely into the machine casing threaded port (M20 or 1/2-20 UNF equivalent).
2. Set the probe tip gap using a feeler gauge or by reading DC gap voltage at the driver module output under zero-speed conditions.
3. Tighten the probe locknut against the machine housing to prevent mechanical unthreading under structural vibration.
4. Route the 1 m armored section and 5 m extension cable through dedicated conduit, maintaining a minimum bend radius of 25 mm.
5. Torqued threaded cable connectors hand-tight and seal all exposed terminal connections with moisture-proof insulating tape.
