Separate Monitor And Attached Monitor Ultrasonic Level Sensor For Water / Oil / Liquid and Solid Measure

Introduction

Ultrasonic sensors are sensors that convert ultrasonic signals into other energy signals (usually electrical signals). Ultrasonic wave is a mechanical wave whose vibration frequency is higher than 20kHz. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, can become a ray and directional propagation. Ultrasonic waves can penetrate liquids and solids very well, especially in solids that are opaque to sunlight. The ultrasonic wave will produce significant reflection when it encounters impurities or boundary surface and form reflection echo. It can produce Doppler effect when it encounters moving objects.

Principle

Ultrasonic sensors are transducers designed to convert ultrasonic signals into other energy forms, typically manifesting as electrical signals. Characterized by vibration frequencies exceeding 20kHz, ultrasonic waves represent mechanical waves with specific attributes that distinguish them within the electromagnetic spectrum.

These waves exhibit high frequency and possess a short wavelength, resulting in minimal diffraction phenomena. Notably, ultrasonic waves demonstrate exceptional directivity, enabling their focused propagation as rays in specific directions. This capability is particularly advantageous in applications requiring precise and directional sensing.

An inherent feature of ultrasonic waves is their adept penetration of both liquids and solids, especially in instances where the latter are impervious to sunlight. This quality extends the utility of ultrasonic sensors to scenarios involving opaque solids.

Upon encountering impurities or boundary surfaces, ultrasonic waves prompt significant reflection, giving rise to distinct reflection echoes. This reflection phenomenon is leveraged in various applications, including distance measurement and object detection.

Furthermore, when ultrasonic waves intersect with moving objects, they induce the Doppler effect. This effect provides valuable information about the velocity and motion of these objects, contributing to the versatility of ultrasonic sensors in dynamic environments.

In summary, ultrasonic sensors exhibit unique characteristics such as high frequency, directional propagation, penetration capabilities, and the ability to generate reflection echoes and Doppler effects. These attributes collectively render ultrasonic sensors instrumental in diverse applications spanning industrial, medical, and automotive domains, where their precision and adaptability are paramount.
