ABSTRACT:
A load-sensitive level detecting device for detecting the level of a powder or liquid comprises a piezoelectric vibrator (3), a case (1) which separates the object whose level is to be detected from the latter, the case (1) being formed with an opening (1b), which is closed by an elastic sheet (2) serving as a movable detecting section, whereby when the load exerted by the object is applied to the elastic sheet (2), the vibration of the piezoelectric vibrator (3) is constrained.
