Abstract

PURPOSE: To completely prohibit powders and grains from contacting with the lead wire of a tuning fork thereby to prevent any accident by forming the tuning fork, which is used to detect the level of the powders and grains, into a shape of leter letter "H" so that one of its vibraory leg, a piezoelectric element and the lead wire may be accommodated in the hollow portion.
