Product Overview
The BBDM-40K-UW is a 40 kHz ultrasonic transducer for underwater depth and distance measurement in liquid media. It is suitable for echo ranging and underwater target detection in rivers, lakes, pools, tanks and industrial liquid environments. Its relatively low operating frequency supports acoustic propagation in water and provides a wide measurement beam.
Key Features
- 40 kHz center operating frequency
- 50° beam width
- 50 to 200 W power range
- Acoustic measurement in liquid media
- G1″ threaded mounting structure
