| With the KEH-721, a human hair sensor detects
expansions and contractions caused by changes
in relative humidity. These changes are transmitted
to a differential transformer and converted
to an electric voltage. A translator then
adjusts the voltage to a specified level
corresponding to the relative humidity to
create the KEH-721 output. The KEH-721 can
be connected to a recorder, printer, or the
like. |
