Ultrasonics. Hydrophones - Properties of hydrophones for ultrasonic fields up to 40 MHz Ingestion-build-232773 Once a certain level has1 Scope This part of IEC 62127 specifies relevant hydrophone characteristics. This standard is applicable to: hydrophones employing piezoelectric sensor elements, designed to measure the pulsed and continuous wave ultrasonic fields generated by ultrasonic equipment; hydrophones used for measurements made in water; hydrophones with or without an associated pre amplifier.
