Immersible ultrasonic transducer BBDM-100KR1P5M

high-frequencyfor level measurementproximity

100 kHz distance sensing in air
The BBDM-100KR1P5M is an air-coupled ultrasonic transducer designed for short-range distance and presence sensing in automation and industrial equipment. Its 100 kHz center frequency and reference range of 0.15–1.5 m make it suitable for compact proximity detection, short-range positioning, counting and small-scale level measurement.

Build and environmental protection
The transducer features a PTFE housing, IP68 protection rating and a specified pressure limit of 0.3 MPa to support integration where chemical resistance and environmental sealing are required. Weight is 570 g ±5% including the 10 m cable.
