Application of Ultrasonic Sensors in Processing Industry Using GRA Method

摘要

An ultrasonic sensor is a device that measures measuring to an item using ultrasonic sound pulses. An ultrasonic sensor transmits and receives ultrasonic pulses from a receiver to determine the proximity of an item. The main function of ultrasonic sensors is as distance sensors. They are present in anti-collision safety devices and self-parking automotive technologies. Robotic obstruction identification systems and production technology both use ultrasonic sensors. For air-coupled programmers, ultrasonic receivers operate at wavelengths between 30 and 500 kHz. The decrease rate increases with increasing ultrasonic intensity. As a result, high wavelength sensors are more successful for short durations and low energy sensors (30–80 kHz) are more useful for long distances. Ultrasonic sensors are very good at reducing background contamination since the time of movement, not sound quantity, is used to calculate the proximity to an objective. Despite of an object's color, it can be identified if it reflects sound. Alternative: speed of Sound, Density, Acoustic Impedance, Reflection Coefficient. Evaluation Preference: Water, Honey, Well-mixed, Well-mixed flour-water, Glass, Pyrex. from the result it is seen that Honey and is got the first rank whereas is the Glass, Pyrex got is having the lowest rank”. The value of the dataset for ultrasonic sensor in GRA (Gray-related analysis) shows that it results in Honey and top ranking”.
