ceramic piezoelectric sensor body, ultrasonic transducer pipe
Applications of ultrasonic transducer:
The ultrasonic flow sensor measures liquid flow rate by
transmitting ultrasonic wave in the liquid medium. In addition to
flow metering, it can also be used for liquid level measurement. These are mainly used in measuring applications, such as detection,
B-medical, beauty equipment, acoustic transducer, micro driven,
ultrasonic heat meter, water meter, welder, cleaner, ultrasonic
flowmeter, etc.
Introduction of ultrasonic transducer:
These ultrasonic transducers can send the electrical signals to the
object, and once the signal strikes the object then it reverts to
the transducer. Its sound waves are reflected back to the
transducer by boundaries between tissues in the path of the beam,
that's the boundary between objects. When these echoes hit the
transducer, they generate electrical signals that are sent to the
ultrasound scanner.The ultrasonic piezo sensor is one type of sound-related sensor.
The frequency range of ultrasonic waves is above a certain kHz.
What is it made of: ultrasonic sensor:
The ultrasonic transducer of high frequency, which is made up of an
active element, a backing, and wearplate. Its active element is a
piezoelectric or single crystal material which converts electrical
energy to ultrasonic energy. It will also then receives back
ultrasonic energy and converts it to electrical energy.
