Point-level sensing for alarms and pump protection
The BBDM-2P5M-LS is a 2.5 MHz ultrasonic transducer for liquid level switch systems. It is intended for high- and low-level alarms, detection of liquid presence or absence, pump protection, and level control in industrial equipment.
Its beamwidth is specified as a 0.6° half-power angle at -3 dB. The transducer also provides IP68 protection, operates from -20 to +60 °C, and is rated for pressure up to 10 kgf or 1 MPa.
