Level measurement ultrasonic transducer BBDM-45KR5M

Overview
The BBDM-45KR5M is a 45 kHz air ultrasonic distance transducer with a reference measuring range of 0.3 to 5 m. It is engineered for industrial integration where non-contact distance or level measurement is required, offering IP68 protection and wide temperature tolerance for harsh environments.

Applications

• Tank and vessel level measurement
• Industrial equipment ranging and positioning
• Collision avoidance for vehicles and machinery
• Security perimeter and area monitoring

Range and installation considerations
The 0.3 m near limit and 5 m upper reference distance define baseline layout parameters. Effective performance depends on target size, surface condition and orientation, mounting geometry, and the drive/receive electronics used. Ensure mounting minimizes acoustic obstructions and aligns the beam to the target for repeatable readings.
