8.1. General Description
The MS2E sensor is a surface sensor that can be held by hand or fixed into a core measurement
system. The sensing surface is at the end of a ceramic tube, which is mounted on a metal
enclosure that houses the electronic circuitry (See Figure 7). The sensing surface should be held
in contact with the sample during use. The coil itself is elliptical in shape, giving an improved
spatial response. The user should therefore be aware of the sensor orientation, denoted by two
black marks on either side of the tube.
The MS2E sensor is designed to perform high resolution measurements of magnetic
susceptibility along flat surfaces that have a roughness less than 1mm. Each sensor is
individually calibrated to measure true
c
vol
when measured against a flat surface greater than
10mm depth, and also individually calibrated to compensate for temperature induced drift. The
sensor connects directly to the MS2 meter via a TNC-TNC coaxial cable that can be up to 30
metres in length.
The sensor and calibration sample are supplied in a polycarbonate, foam filled box.
8.2. Characteristics
8.2.1. Spatial Response
The response to magnetic material within the vicinity of the sensing area, when measured in
the plane of the sensor, shows a rectangular profile with a long axis and a short axis. The long
