Electronic scales

Electronic scales are weighing technology in a new type of instrument is widely used in various occasions. Electronic scales and mechanical scales have more small size, light weight, simple structure, low price and practical value of strong, convenient maintenance and so on can be in a variety of environmental work, the weight of the signal can be Remote, the weight of display is easy to implement digital, easy-to-computer network, production automation, higher labor productivity. Scale labels in the supermarket is in the application of face value. A small label contains: name, price, weight, etc. 11 list in this small electronic label. Greatly accelerated the use of label machine sales pace, but also convenient for customers. Top barcode labels have many remarkable features of scale, Ethernet feature makes the management more convenient.

Weight sensor signals are converted to a corresponding electrical signal, after amplified into the A / D converted into pulses weight, through the SCM under the control of the analog voltage signals into digital. The digital conversion by the SCM program in line with the actual weight of the value of sending the number of display windows.

MCU at the same time the keyboard and switch matrix for monitoring. According to the input parameter values, the program handled accordingly. Power circuit to provide the various parts of the operating voltage. Microprocessors such as 8050, HD404418F, 8031, etc. CPU. Highly versatile motherboard, different values of range and sub-degree scales, just adjust the jumpers on the motherboard and the DIP switch can be achieved, the only difference is that the sensor used with a rated carrying capacity

Sensor is a physical device or biological organ that can detect and feel the outside of the signal, physical condition (such as light, heat, humidity) or chemical composition (such as smoke), and Discovery of information to other devices or organs. Definition of sensor

National standard GB7665-87 sensor is defined as: "can feel the requirements are measured and converted in accordance with the laws of certain signal device or devices available, usually composed of sensitive components and conversion devices." Sensor is a detection device, can feel the information being measured, and can detect sense of information, according to certain laws of transformation into electrical signals, or other forms of information required for output to meet the information transmission, processing, storage, display, recording and control requirements. It is the automatic detection and control of the primary link.

The role of sensor

People in order to obtain information from the outside world must help of sense organs. And rely on people's own sense organs, the study of natural phenomena and laws, and production activities in their functions on far enough. To meet this situation, we need sensors. It can be said sensor is an extension of human senses, also known as electronic features.

The arrival of the new technological revolution, the world entered the information age. In the course of the use of information, we must first resolve is to obtain accurate and reliable information, and sensors is to obtain information in

the field of natural and production of the main ways and means.

In modern industrial production, especially automated production process, the use of various sensors to monitor and control the various parameters of the production process, so that devices work best in the normal state or condition, and to achieve the best quality products. Therefore we can say, without a large number of good sensors, modern production base will be lost.

In the basic science research, a more prominent position sensor. The development of modern science and technology into many new areas: for example, thousands of light years to observe the macro level of the vast universe, to observe microscopically small particles cm the world, vertical, to observe the evolution over hundreds of years of celestial bodies , a short response to the s moment. In addition, there was even a matter of deepening understanding, developing new energy, new materials, play an important role in a variety of extreme technology such as ultra-high temperature, ultra-low temperature, high pressure, ultra-high vacuum, powerful magnetic field, ultra-weak magnetic bagging, etc. . Obviously, to obtain a large number of human senses can not directly access the information, Not compatible with sensors is impossible. Many basic scientific research obstacles, first of all to obtain information on the object is difficult, and a new highly sensitive detection mechanism and the emergence of sensors, often lead to breakthroughs in the field. The development of a number of sensors is often a pioneer in the development of marginal subjects.

Sensor has already penetrated into, such as industrial production, space development, marine exploration, environmental protection, resource survey, medical diagnostics, biotechnology, and even conservation areas and so most of the pan. It is no exaggeration to say that, from the vast space, the vastness of the ocean, as well as a variety of complex engineering systems, almost every modern project, are inseparable from a variety of sensors.

Thus, the sensor technology in economic development, promote the important role of social progress is very clear. Countries in the world attach great importance to the development of this area. I believe in the near future, there will be a leap in sensor technology, to achieve status commensurate with its important new level.

Sensor classification

Different views can be classified on the sensors: they transform principle (Transducer on the basic physical or chemical effect); their purpose; their output signal types and the production of their materials and processes.

Working principle of the sensor can be divided into physical sensors and chemical sensors two categories:

Sensor working principle of the classification of physical sensors that physical effects, such as the piezoelectric effect, magnetostriction, ionization, polarization, thermal, optical, magnetic and electric effects. Small changes in the amount of the measured signal will be converted into electrical signals.

Chemical sensors, including those with chemical adsorption, electrochemical reaction, a causal relationship between the phenomenon of the sensor, the measured signal will be small changes in volume converted to electrical signals.

Some sensors can not divided into physics, can not be divided into chemical classes. Most of the physics-based sensor is functioning. Many problems of chemical sensor technology, such as reliability issues, the possibility of mass production, prices, etc., solve such problems, the application of chemical sensors will have tremendous growth.

Dynamic characteristic

The so-called dynamic characteristics, is the change in the input sensor, its output characteristics. In practice, the sensor's dynamic characteristics common to certain standards of its response to said input signal. This is because the sensor response to the standard input signal easily obtained by experiment, and its standard input signal response and its response to any input signal exists between the relationship, often the latter that the former can be presumed. The most commonly used standard input signal and sine signal with step two, so the dynamic characteristics of sensors are commonly used in the step response and frequency response to that.
