Bartington MS2E High Resolution Surface Sensor

Bartington MS2E High Resolution Surface Sensor

MS2/MS3 Brochure

The MS2E1 sensor is designed to perform high resolution measurements of magnetic susceptibility along flat surfaces which have a roughness less than 1 mm. It is expected that the sensor will most frequently be used to investigate lamination in split drill or soft sediment cores. Soft or wet cores should be protected by a thin plastic film of a thickness less than 0.05 mm. This also prevents the pick-up of potentially contaminating material on the sensor’s measurement surface which would otherwise create inaccuracies.

The MS2E1 sensing surface is at the end of a ceramic tube. The tube is mounted on a metal enclosure which houses the electronic circuitry. The sensor is connected directly to the MS2 meter via a TNC-TNC coaxial cable which may be up to 30 meters in length.

The sensing surface is protected by a thin ceramic (aluminum oxide) plate which is held in intimate contact with the surface of investigation during the measurement period. The full-width-half-maximum (FWHM) response measured in two axes in the plane of the sensing surface has linear dimensions of 3.8 mm (short axis) x 10.5 mm (long axis). The depth response below the surface of investigation falls to 50% at 1 mm and 10% at 3.5 mm. A complete measurement is accomplished in 1.3 seconds when the MS2 meter is set to x1.0 CGS and the sensor is calibrated to read true K when in contact with a large (infinite depth) surface.
