Ultrasonic piezoelectric transducer S0807 DATA SHEET Intended use The S0807 transducer is designed to perform a nondestructive ultrasonic testing of objects made of cast-in concrete and as a part of ultrasonic monitoring systems used to inspect solid concrete structures. The transducer is embedded into the concrete structures at the stage of their construction.
