Description

IEC 62092 Ed. 1.0 en – Ultrasonics – Hydrophones – Characteristics and calibration in the frequency range from 15 MHz to 40 MHz

Applies 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 and in the frequency range between 15 MHz and 40 MHz; – hydrophones with or without an integral amplifier; – hydrophones with a circular piezoelectrically active element. Specifies – relevant hydrophone characteristics; – methods of determining directional response and hydrophone sensitivity based on relative or comparative measurements; and describes – absolute hydrophone calibration methods. Recommendations and references to accepted literature are made for the various relative and absolute calibration methods in the frequency range covered by this International Standard.
