Ultrasonic transit-time ultrasonic transducer BBFM-Q70K

high-temperaturehigh-frequencymeasurement

Overview
The BBFM-Q70K is an ultrasonic flow transducer with a 70 kHz center frequency designed for flue-gas flow measurement, boiler exhaust monitoring, industrial emission ducts and high-temperature gas transit-time measurement. The operating temperature range is -40 to +150°C. Maximum pressure must not exceed 3 kgf (0.3 MPa). The transducer features an IP68 protection rating and a 304 + LY12 housing suitable for high-temperature gas applications.
