ABSTRACT:
A method for protecting ultrasonic transducers from deterioration for use in devices having multiple transducers immersed in a liquid reservoir comprises the steps of placing each transducer within an isolation territory within the reservoir such that the territory is topologically bounded by at least one conductive member with the transducer and conductive member having no electrical contact. The potential between the conductive members is balanced by electrically interconnecting the members. The vibrating surface of each transducer and the centroid of each associated isolation territory are oriented approximately coaxially.
