MEASURING SENSOR FOR SIMULTANEOUSLY MEASURING A FORCE THAT CAN BE BOTH DYNAMIC AND STATIC

机译:同时测量动态和静态力的测量传感器

摘要

A measurement transducer for simultaneously measuring a force that can be both dynamic and static includes at least one piezoelectric transducer element having element surfaces on which the force generates electrical polarization charges proportional to a magnitude of the force. The measurement transducer includes a resonator element which can be excited to at least one resonance frequency and undergoes a transverse expansion from the action of the force in a transverse direction to the force. The magnitude of the transverse expansion is proportional to the magnitude of the force and causes in the resonance frequency a change that is a function of the force.
