Ultrasonic sensor
Other |
The principle of ultrasonic sensors involves applying a high voltage to a transducer to make it vibrate and generate sound waves (like a speaker). When the sound waves bounce back from an object and hit the transducer, a voltage is generated (like a microphone), allowing for time measurement. This time can be converted into voltage and current, enabling distance measurement, as the speed of sound is approximately 330 m/s. Each series includes two types: an analog output type for distance measurement and a digital (switching) output type for detecting the presence of an object within a set distance range. The analog output type is typically used for distance measurement, with a current output usually in the range of 4-20 mA. A common application is measuring the liquid level in tanks, and it is also referred to as a level sensor. Recently, there have been increasing examples of using analog output as an obstacle sensor. The digital output (ON/OFF) is mainly used as an obstacle sensor, particularly mounted on unmanned transport vehicles to prevent collisions with people or vehicles. It performs control functions such as deceleration and stopping. | For example, golf carts are now electric, and unlike the old engine types, they move silently (with a maximum speed of 20 km/h?). Moreover, during tee shots, they can drive automatically via remote control. Although they run on a designated path (using electromagnetic induction), if there are players on the path, it could lead to collisions and accidents. The OM5 series supplied by our company can detect up to 5 meters with two open collector outputs for both near and far detection. When it detects something at 5 meters, the cart slows down, and if it detects something within about 2.5 meters, it stops. In another example, two sensors can be placed a certain distance apart along the roadside to measure the speed of passing vehicles or the size of the vehicles. In the railway sector, there are applications where sensors detect when a train is entering a station, automatically turning on the monitor's display. There are countless applications for measurement, and I believe that unlike light, it is particularly advantageous because it is not affected by colors and can detect over a wide angle. | |
