Immersible ultrasonic transducer BBDM-2P5M-LS

high-frequencyfor level measurement

Overview
The BBDM-2P5M-LS is a 2.5 MHz ultrasonic transducer designed for liquid level switch systems in industrial applications. It is intended for high- and low-level alarms, detection of liquid presence or absence, pump protection, and level control. The transducer features a 0.6° half-power beamwidth at -3 dB, IP68 protection, an operating range of -20 to +60 °C, and a pressure rating up to 10 kgf (1 MPa).
