Ultrasonic sensor



Ultrasonic sensor (Digital type)


An ultrasonic sensor mounted above the product is  electrically excited and directs an ultrasonic pulse through  the air  towards the product .This pulse is reflected back from the surface of the product. The echoes partially  reflected are detected by the same sensor, now acting as receiver and converted back into an  electrically  signal . The time taken between transmission  and reception of the pulse the time of flight is directly Proportional to the distance between the sensor and the product surface .

  2. There are quite a few places that you might consider to stay for safety issue. But if you need to monitor something like liquid, gas or other element from that place then let’s take a quick look without any second thought, you should consider mounting wireless tank level sensor. It can be monitor from anywhere through wireless network and the device is suitable for any flammable liquids or gases over hot surface or cold surface.
