Piezo Ceramic 20*10mm Ultrasonic Transducer for Heartbeat Baby Monitor
Description:
The use of piezoelectric ultrasonic Doppler probes can not only detect fetal heartbeat, but also detect the movement of adult heart and valves, diaphragm movement, blood flow, and determine whether blood vessels are blocked. Common operating frequencies range from 2MHz to 10MHz. At present, we are mass producing 2MHz and Hz piezoelectric ceramic transducers for fetal heart rate measurement.
