Rotational speed sensor
A1S30P
American Hofmannoration
detect the speed of rotating shafts in
connection with the portable Hofmann
instruments EB3100, MI2100
and VL8000. The A1S30P is applicable
for a broad speed range.
To generate a measuring pulse a
mark (either coloured mark or piece
of reflective tape) is applied to the
rotor surface, which has a high
contrast to the background.
