Spice model of a piezo-electric transducer for pulse-echo system

Pulse-echo system is the most widely used equipment in non-destructive testing (NDT). Herein we present the SPICE implementation of a piezo-electric transducer for pulseecho system. The SPICE model has been developed with an intention to obtain a virtual instrument for the pulse-echo system. The SPICE implementation of pulse-echo system includes the lossless piezoelectric transducer as an actuator and the sensor. The output of actuating stage is fed into the sensing stage of the sensor stage. The simulated results in the actuation and sensing modes are compared to the previously reported experimental results and the output trends are in good agreement. Findings from the comparative study, validate the application of our proposed model as a virtual system for pulse-echo system for non-destructive testing.
