Immersible ultrasonic transducer BBDM-D12K

low-frequencyfor level measurementfor obstacle detection

Overview
The BBDM-D12K is a 12 kHz underwater ultrasonic transducer for ranging and depth measurement with a reference range of 10000 m. Designed for integration on ROVs, AUVs, survey vessels and fixed installations, it is suited for obstacle avoidance, distance measurement in tanks and open water, and underwater target detection.

Horizontal acoustic coverage
The acoustic field is horizontally omnidirectional, simplifying target tracking and allowing flexible mounting orientation. Consider the omnidirectional beam when defining measurement geometry, target coverage and required acoustic path.

Operating specifications
Model — BBDM-D12K
Center frequency — 12 kHz ±5%
Recommended range — 10000 m
Operating temperature — -40 to +80°C
Pressure rating — ≤10 kgf or 1 MPa
Acoustic field — Horizontally omnidirectional

Applications

• Underwater ranging and depth measurement
• Obstacle avoidance for underwater robots (ROV/AUV)
• Distance measurement in tanks and water bodies
• Underwater target detection and monitoring

System selection
Selection should account for the operating medium and temperature, required distance and acoustic path, target size and surface condition, available installation space, operating pressure, ingress protection, and the drive/receive electronics. Verify mechanical and electrical compatibility with the hosting vessel or vehicle and with signal‑processing equipment.
