DEVICE FOR MEASURING PARAMETERS OF A PIEZOELECTRIC TRANSDUCER

The proposed device for measuring parameters of a piezoelectric transducer contains an inductance coil and a capacitor, which are connected to each other, with a possibility to adjust the impedance, and to the transducer, a capacitor that is connected in parallel to the transducer, a field-effect transistor, an ammeter, and a power-supply unit. The drain of the transistor is connected to the common point of the connection of the circuit with the inductance coil and the capacitor to the transducer and, via a capacitor, to the common point of the circuit of the device. The source of the transistor is connected to the common point of the circuit of the device. The ammeter is inserted between the drain of the transistor and the power-supply unit via an inductance coil.
