A sensor is a physical device or a biological organ that can detect, perceive external signals, physical conditions (such as light, heat, humidity) or chemical composition (such as smoke), and transmit the information to other devices or organs. Sensors have penetrated into a wide range of fields such as industrial production, cosmic development, marine exploration, environmental protection, resource surveys, medical diagnostics, bioengineering, and even cultural relic protection. It is no exaggeration to say that from the vast space, to the vast ocean, as well as Sensor a variety of complex engineering systems, almost every modern project, are inseparable from a variety of sensors. Classification of sensor working principle Physical sensors use physical effects, such as piezoelectric effects, magnetostrictive phenomena, ionization, polarization, thermoelectric, photoelectric, magnetoelectric and other effects. A small change in the measured signal will be converted into an electrical signal. Chemical sensors include those with chemical adsorption, electrochemical reactions and other phenomena as a causal relationship between the sensor, the measured signal changes will be small changes into electrical signals.

It is widely used in transportation, electric power, metallurgy, chemical industry and building materials. It is widely used in transportation, power, metallurgy, chemical industry and building materials. It is widely used in transportation, power, metallurgy, chemical industry and building materials. And other areas of automation equipment and production automation process. The research and application of detection technology and automation device not only have important theoretical significance, but also conforms to the strategy of China's science and technology development Fuel Rail Pressure Sensor in the past and for a long time, and it is closely integrated with the actual situation of the national economy. It is of great significance to promote technological progress and traditional industrial technological transformation And the modernization of railway technology and equipment has important significance.

Using the distance detection sensor designed and developed by the Fraunhofer IPT Institute, it is possible to simultaneously perform nano-scale accuracy detection of the shape and position error of the machined parts at a number of different detection positions. This technology in the aerospace, automobile manufacturing, printing machinery manufacturing and optical equipment manufacturing can be a very good application. The detection technology Speed Sensor is suitable for those traditional detection solutions because of the limited use of space, and the traditional detection technology can not meet the detection accuracy of the occasion. This detection frequency is very high, the detection error is significantly less than the high-precision detector, can achieve the machine and equipment in the ultra-precision range of online testing, such as machine movement axis and rail movement monitoring and transmission shaft monitoring.

When the measured object enters within the inspection range, an inherent feature interferometric light sample decoded by the CCD charge coupled camera will be generated. The horizontal position of the interference signal is used to compensate the distance of the object to be measured in the CCD chip, and the pitch adjustment amount is converted into the number of pixels of the image. If you want to economically handle energy and resource issues, machine tools and equipment must be monitored during continuous use. To this end, an easy integration of sensor technology has become a timely machine and equipment maintenance, to ensure product quality, to avoid downtime and improve the stability of the production process of the key factors. High-precision production process monitoring requires data from the production process as a guarantee, which should be provided by those sensors installed on the machine tool. Most of the sensors responsible for this monitoring and monitoring task are fiber optic sensors, which have a very high detection accuracy of miniaturized fiber optic sensors, so that it can be easily integrated in the machine tools, equipment and testing equipment, can be very good to complete monitoring and Data transfer tasks.

The pitch detection sensor is capable of simultaneously performing nanoscale accuracy detection of the shape and position error of the machined part at a plurality of different detection positions. This technology in the aerospace, automobile manufacturing, printing machinery manufacturing and optical equipment manufacturing can be a very good application. This detection technology is suitable for those traditional detection solutions due to the limited use of space for installation, and traditional detection technology can not meet the detection accuracy of the occasion. This detection frequency Throttle Position Sensor is very high, the detection error is significantly less than the high-precision detector, can achieve the machine and equipment in the ultra-precision range of online testing, such as machine movement axis and rail movement monitoring and transmission shaft monitoring.
