NYKC3 External Ultrasonic Level Switch of Non-Invasive Design Ultrasonic Level Switches Explosive Gas Environments
NYKC3 External Ultrasonic Level Switch Working Principle
This switch uses ultrasonic technology to detect whether the liquid level inside the tank reaches the set alarm position through the ultrasonic sensor. The principle is that by stimulating the ultrasonic sensor, the ultrasonic wave is emitted and the ultrasonic signal is shot into the tank with the tank wall. Therefore, there will be a clear difference in the strength of the reflected signal from the tank wall received by the ultrasonic sensor. Using the above principle, by detecting the strength of the received ultrasonic signal, it is possible to accurately determine whether the liquid level has reached or not, and the relay outputs the corresponding alarm signal.
