The invention relates to a force transducer, comprising an oscillator (1), with an inductance (2), formed by a primary winding and a measuring transducer (11), with a secondary winding (30), electrically-connected to the measuring transducer (11) and arranged with a transformer coupling to the inductance (2) of the oscillator (1). On exertion of a force on the measuring transducer (11), the impedance of the measuring transducer (11) is altered, along with the load in the inductively-coupled secondary winding (30). The resulting frequency change in the oscillator (1) is determined by means of an analytical circuit (14) which is proportional to the force acting on the measuring transducer (11). |
