FIELD: measuring technology; used in various branches industry to measure mechanical efforts. SUBSTANCE: device comprises generator of electric oscillations, two piezoelements with three outer plates placed in parallel. One of the plates is connected to generator and two others, to signal comparator where measuring instrument is linked. Two piezoelements are acoustically coupled with the aid of two coupling elements, one being immersion, manufactured in the form of thin layer of fluid located between piezoelements. Contact area of piezoelement via immersion element depends on value of measured force. EFFECT: considerably increased sensitivity and stability of measurements. |
