material (other than the target) that is positioned within 3 times the
diameter of the sensor and is a permanent part of the measuring
environment.

Simulated vs. Application Fixture

Install the sensor in the application fixture exactly as it was in the simulated
one. When moving from the simulated fixture to the application fixture,
deviations may occur through changes in loading or in mechanical position.
To ensure maximum accuracy, calibrate the sensor in the actual application
fixture whenever possible.

Conductive Materials in the Measuring Area

Keep in mind the following general rule: Mount unshielded sensors 2.5 to 3
times their diameter away from conductive materials; for shielded sensors
use a factor of 1.5 to 2 times diameter.
