axis direction is marked on the circumference of the ceramic enclosure and the direction is
also shown symbolically on the sensor label. The rectangular response permits two modes of
operation.
• With the long axis parallel to narrow strata, the maximum spatial sensitivity is obtained for
detailed measurements.
• With the long axis perpendicular to the strata, the measurement is integrated over a longer
interval and an average value is obtained.
A detailed description of the spatial response is shown in Figure 8.
Figure 8. MS2E response characteristics.
Two response characteristics are given:
1. Response to narrow stratum (in the plane of the sensor). This shows the full width at half
maximum (FWHM) response to be circa 11.5mm with the long sensing axis perpendicular to
the stratigraphy, and circa 3.8mm with the long sensing axis parallel to the stratigraphy.
2. Depth response (normal to the plane of the sensor). This shows the rate at which the
relative response falls off with depth below the surface of the sensor. The response is
reduced by approximately 50% at a depth of 1mm.

8.2.2. Conductivity
Note: Measurement of conductors by the sensor is restricted to those which are relatively
poor, or are in shapes which do not form a conductive loop.
