FIELD: defectoscopy.
SUBSTANCE: use for testing of ultrasonic flaw detector. Gist of the invention is testing of each of the piezoelectric ultrasonic sensors of an ultrasonic flaw detector is carried out using a device made with a through cylindrical cavity, at the same time, a measure and piezoelectric ultrasonic sensor are installed in the through cylindrical cavity, ensuring their fixation in the device, liquid fills the space between the lens of the piezoelectric ultrasonic sensor and the gauge and checks the operability of the piezoelectric ultrasonic sensor.
EFFECT: higher calibration accuracy and enhanced functionality.
