Sensor (English name: transducer / sensor) is a detecting means, feel measured information, and can feel the information, according to certain rules converted into an electrical signal or other forms of information output required to meet the information transmission, processing, storage, display, recording and control requirements. Features sensors include: miniaturization, digital, intelligent, multi-functional, systematic, network. It is the automatic detection and automatic control of the primary link. The existence and development of the sensor, so that the object had touch, taste and smell and other senses, so that the object gradually became alive again. The basic functions are usually divided into thermal sensing element, the photosensitive element, gas sensors, force-sensitive components, magnetic components, humidity sensor, acoustic sensor according to its top ten class radiation-sensitive elements, color and flavor-sensitive components and other sensitive components . Displacement sensors, also known as a linear sensor, the displacement sensor is converted to electricity. Linear displacement sensor is a device belonging to metal induction, the role of the sensor is converted to a variety of measured physical power which is divided into inductive displacement sensors, capacitive displacement sensors, photoelectric displacement sensors, ultrasonic sensors displacement sensors, Hall Seoul displacement sensor. In this conversion process, many of the physical quantity (e.g., pressure, flow, acceleration, etc.) often need to be converted into a displacement sensor classification, and then converted into electricity displacement. Therefore, the displacement sensor is an important class of basic sensors. In the production process of high quality sensors, displacement measurement and displacement measurements are generally divided into two kinds of physical machinery. Mechanical displacement including linear displacement and angular displacement. Form according to the measured variable transformation is different, displacement sensors can be divided into two kinds of analog and digital. Analog type can be divided into physical properties (such as self-generating) two and structured. Displacement sensors used to simulate the structure type in the majority, including the potentiometer displacement sensors, inductive displacement sensors, selsyn, capacitive displacement sensors, eddy current displacement sensors, Hall displacement sensors. An important advantage of digital displacement sensor is to facilitate the signal directly into the computer system. The rapid development of this sensor, is used widely.
