摘要

The measuring device to perform a measurement of electric power impedu00e1ncia method to perform a measurement of impedu00e1ncia electrical, and computer program product. The invention relates to a measurement device to perform a measurement of electrical impedance in a way without electrical contact.The measuring device comprises a measuring unit which is provided with the impedance (7,8) to be measured, and a passive resonance circuit (4) connected to it to generate a measurement signal to be received by wireless transmission by a transmission unit and recepu00e7u00e3 The active separated for determination of electrical impedance.When the wireless receiving a signal mark transmitted by the transmission unit and a reception active. Still, the measuring unit is provided with an additional reference circuit (5) which is preferably connected to the resonance circuit, depending on the sign of the query to generate a reference signal to be received by the unit of transmission and reception is active.
