Differences vs. Base Model (PR6426/000-030)

"-CN" Suffix: Typically denotes:

A connector variant (e.g., different plug type for regional markets).

Custom labeling/packaging for specific regions (e.g., China).

Possible minor electrical specs adjustments (verify datasheet).

Applications

Shaft vibration monitoring (turbines, compressors).

Position measurement (thrust bearings, rotors).

Machinery protection systems.

Installation Notes

Connector Compatibility:

Confirm the "-CN" connector matches your monitor's interface (may differ from standard Bently Nevada connectors).

Gap Calibration:

Set to -10V DC at mid-range (1.0–1.5 mm gap).

Wiring:

Ensure proper grounding to avoid noise interference.
