: A force measuring device comprising: a rigid base plate; a first diaphragm symmetrical about a central normal axis and being arranged in spaced parallel relationship to said base plate; an elastic connection between said base plate and a peripheral rim of said first diaphragm, hermetically closing a cavity between said base plate and said first diaphragm; a first projection formed for force introduction to said device on an outer surface of said first diaphragm and extending along said central normal axis; a second projection extending from an inner surface along said central normal axis toward said base plate; and a displacement sensor arranged in said cavity between said base plate and said second projection for sensing any displacement therebetween upon force application onto said device, and generating an electrical signal indicative of the force applied. |
