Beschreibung
Zusammenfassung:	The invention provides a piezoelectric transducer detection device and method for steel rail total cross-section defect detection. The piezoelectric transducer detection device for steel rail total cross-section defect detection comprises first to ninth piezoelectric transducers, a steel rail comprises a rail head, a rail waist and a rail bottom, the rail bottom is divided into a short limb side area, a rail waist lower area, a long limb side middle area and a long limb side outer area, the first piezoelectric transducer is installed in the short limb side area, and the second piezoelectric transducer is installed in the long limb side outer area. The second piezoelectric transducer is installed in the area below the rail waist, the third piezoelectric transducer is installed in the middle area of the long limb side, the fourth piezoelectric transducer is installed in the area outside the long limb side, the fifth piezoelectric transducer and the ninth piezoelectric transducer are distributed on the two sides
