Product Overview
The BBDM-500KR5M is a 500 kHz ultrasonic transducer for liquid-level and distance measurement over a range of 0.02 to 5 m. It combines an 8° beam width with a blind zone below 20 mm for integration into tank, vessel and industrial-equipment level-measurement systems. The aluminum-alloy housing is supplied with a fixed cable and temperature-signal leads.
