ABSTRACT:
A transducer identification system provides transducer characteristic information to an echosounder. The echosounder, in turn, utilizes the transducer characteristic information to alter its functionality or parameters to optimize its performance. The transducer characteristic information can be any combination of a) the resonant frequencies of the transducer; b) the impedances of the transducer at the transducer's resonant frequencies; c) the transducer's power rating; d) the date of manufacture of the transducer; e) the peak transmitting voltage response of the transducer; f) the receiving voltage response of the transducer; g) the figure of merit of the transducer; h) the model number of the transducer; i) the serial number of the transducer; j) the transducer's aging coefficient; k) information regarding the configuration of the transducer, such as the housing style, arrangement of piezoelectric elements, and type of acoustic window; l) the beam width of the transducer; m) configuration and calibration information regarding an included temperature sensor; and n) configuration and calibration information regarding an included speed sensor.
