The major part of the noise is caused by the signal conditioning circuitry. Resolutions in the order of 0,001° or 7µg/√Hz (KAS901-4x) are possible. 2.

Then the mounting has to be so, that the “potting” side is on the upper side. For that we offer an additional cap. Please contact our local sales representative or factory.
