500KHZ Barometer Ultrasonic Transducer
Product Description
working at the frequency at 500KHz. Comparing with low frequency transducer, it is much narrower in FOV(<10°) & more precise (mm resolution). By using the calculation of TOF ( Time of Flight), this transducer can be used to measure not only short range distance, but also for air/gas flow, etc.
