Field Installation Guidelines
Install probe tip perpendicular to shaft surface for accurate displacement readings.
Maintain insertion depth to align with –10 VDC gap reference calibration.
Route cable with shielding grounded at a single point to minimize interference.
Avoid sharp bends in cable to prevent conductor fatigue.
Verify O‑ring seal integrity to maintain pressure resistance.
Confirm driver calibration after installation to ensure proper sensitivity scaling.
