IEC 62092:2001 ED1

Ultrasonics - Hydrophones - Characteristics and calibration in the frequency range from 15 MHz to 40 MHz

Апстракт

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.
