Ultrasonic technology is a rapidly growing technology that is used in numerous industrial applications. This article will focus on the application field and working principle of the MB7363-820, an all-in-one ultrasonic receiver and transmitter that has the ability to operate for long-duration applications with no compromise on performance or range.

The MB7363-820 offers several advantages for portable ultrasonic applications, such as mounting flexibility, a strong signal-to-noise ratio, and the ability to determine target objects through sound reflections. It can detect objects up to 10m away, and its output is crisp and clear even at long ranges. It is suitable for various industries, including automotive, health care, marine, and agriculture.

The MB7363-820 operates on a conventional ultrasonic technology known as “time-of-flight”. This technology is based on the linear relationship between the speed of sound and time. When an acoustic signal is emitted from the transducer of the MB7363-820, it propagates outwards until it reaches an object, at which point it will be reflected back to the receiver in the form of an echo. The time the signal takes to travel back to the receiver is then measured and used to calculate the distance of the object from the transmitter.

The receiver in the MB7363-820 is designed to detect the returning echo and process accurately the intensity and direction of the received signal. It can detect reflected signals from up to 10m away with an accuracy of better than 5mm. The signal is then processed and information can be determined based on the amplitude of the reflected signal. For example, a large signal amplitude will be indicative of a large object in close proximity while a low signal can be used to determine a smaller, distant object.

The transmitter included in the MB7363-820 is a two-channel unit. It includes an amplifier and a digital signal processor (DSP) to convert the digital signal into an analogue signal. The amplifier then amplifies the signal up to 130 dB above ambient noise, while the DSP filters the signal to reject unwanted noise. It also performs fast Fourier transformation to analyze and extract information from the received echo.

The MB7363-820 is a robust and reliable ultrasonic device and is ideal for various applications, including obstacle avoidance, security systems, and medical imaging. It offers excellent performance in terms of range and accuracy, making it perfect for situations where accuracy and range are paramount. Furthermore, its easy setup, compact size, and Plug-and-Play compatibility make it an ideal choice for a variety of environments.
