High-frequency ultrasonic transducer BBND-T

measurement

Overview
The BBND-T is a 90 kHz ultrasonic transducer designed for detection of internal defects in standing trees and sawn timber. It is intended for use in tree health assessments, trunk decay and cavity detection, internal timber inspection and integration with tree acoustic tomography systems. The transducer features an ABS+PI housing and IP68 ingress protection for reliable field operation across a wide temperature range.
