Product Overview
BBID-EC is a 170 kHz rectangular ultrasonic transducer for industrial error-correction, position-adjustment, and alignment-sensing systems. Its rectangular acoustic aperture produces different beam angles along the length and width axes, providing a directional ultrasonic signal for detecting position changes in moving materials.
The transducer can operate as an ultrasonic transmitting or receiving element in controllers, sensing modules, and automated equipment. It is suitable for position monitoring and correction of sheets, webs, and other moving materials.

Beam Characteristics
The rectangular acoustic aperture gives BBID-EC different directivity in the two principal axes:
- Full beam angle along the length axis: 5° ± 1°
- Full beam angle along the width axis: 10° ± 1°
The narrow beam supports directional position sensing in correction and alignment systems.
