ISAS3-SpecMount
This describes an alternative mounting method of ISAS3 using welded screws instead of
magnets.
The mounting plate shall be fastened by three M5x16 screws (instead of magnets), with
hexagon screw-heads welded to the test object. The boreholes "B", 9 mm with MAG4IS, shall
be 5.1 mm for the welded holder. Each screw holds the mounting plate using screw-nuts and
washers on both sides. The mounting plate comes with the three screws already mounted and
the distance between screw-heads and mounting plate adjusted to 10 mm.

(39MMP1_R0.2 of 29.04.2011)
A sensor position must be found, where the area between three welding points is perfectly flat
and where the sensor's sensitive face will meet a clean surface. The three screw-heads holding
the mounting plate shall be welded to the test object. Then the sensor ISAS3, with some
coupling agent on the sensitive face, shall be mounted to the mounting plate using three screws
M4, exactly as with MAG4IS (Figure 8-3), to threads "A" in Figure 8-1. If the test object's surface
is not perfectly flat, the three pairs of screw-nuts must be loosened, the best position found and
the screw-nuts re-fastened. The best position is found, when the sensor's sensitive area is
exactly parallel and pressed onto the test object surface.
