Product Details
4MHZ ultrasonic transducer, ceramic piezoelectric sensor for heat meter
Ultrasonic transducer application:
In addition to flow metering, the ultrasonic piezo transducer can 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. The ultrasonic flow sensor measures liquid flow rate by transmitting ultrasonic wave in the liquid medium.
Working principle of ultrasonic transducer:
The piezoelectric ultrasonic transducers are used in an ultrasonic flow meter, it uses sound waves to determine the velocity of a fluid flowing through a closed pipe, and its reflections from the fluid are the same. The transmitter processes upstream and downstream times to determine the flow rate.
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.
