Classification of the sensor

Sensor industry is a knowledge-intensive, technology-intensive industries, it is relevant to many disciplines, and a very large variety. The following will now widely used as a sensor classification brief.1 According to the working principle of classification sensorThis is Position Sensors classification sensor, this classification will be physics, chemistry, biology and other disciplines principle, rules and effect as a basis for classification, help explain the working principle of the sensor and the sensor in-depth research and analysis, but Depending on the application the user is not easy to choose.Sensor works according to Position Sensor the different sensors can be divided into electrical parameter sensors (including resistive, inductive and capacitive sensors), piezoelectric sensors, photoelectric sensors (including general photoelectric, fiber type, laser type and infrared type sensors, etc.), thermal sensors, semiconductor sensors, and radiated wave sensors. Most of these types of sensors respectively, based on their respective physical effect principle named.(2) the purpose of classification according to the sensorClassified by the use of sensors, such as displacement sensors, pressure sensors, vibration sensors, temperature sensors,sensors on people Crank Position Sensor use.3 categories according to the sensor materialIn recent years, research and development of the sensor material has greater progress, with the complexity of materials to create a more favorable performance of the sensor is one of the direction of future development.
1) semiconductor materialSemiconductor materials in sensor technology have a greater advantage. It has the sensitive nature of many of the amount of information, but also a mature integrated circuit technology, easy to implement multi-functional, integrated and intelligent, but also a good base material, it is ideal Crankshaft Sensor. Which is the most used silicon material. Silicon light weight, has a high strength to density ratio and stiffness to density ratio and therefore suitable for making sensors. In force-sensitive semiconductor silicon, thermal, photo, magnetic, gas, ion-sensitive areas and other sensitive components have wide applications.
