Understanding How Ultrasonic Sensors Work

24/03/2020· How Ultrasonic Sensors Work. Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo. The sensor determines the distance to a target by …

Life of wide-band O2 sensor with leaded fuel - Engine ...

01/09/2005· As Fader said, the sensor to run is the NTK UEGO sensor, but the cheaper versions of these are still prone to failure with leaded fuel. The lab grade versions are better in this respect. If you can avoid starting the engine cold on leaded fuel, you can greatly extend the life of the sensor. My dyno operator is meticulous about this and the sensor he bought 11 years ago still works fine after thousands of runs on leaded fuel. …
