A240B 240 kHz Air transducer
P/N: H2KA240KB1CD00

A240B works as a signal transmitting and receiving unit. This ultrasonic transducer is suitable for gas flow detection with high sensitivity, low noise, low ZFD (zero flow drift), high precision as well as exceptional reliability. In particular, the transducer housed with PVDF material is FDA compliance and free from corrosion by chemical solvent.
