The development direction of sensors
(1) towards high precision: with the continuous improvement of the degree of automatic production, the requirements for sensors are also increasing. We must develop new sensors with high sensitivity, high accuracy, fast response speed and good interchangeability to ensure the precautions of Leeb hardness tester and ensure the reliability of production automation. Recently, sensors with an accuracy of more than 1/10000 can be produced
(1) develop to high accuracy: with the continuous improvement of the degree of automatic production, the requirements for sensors are also increasing. We must develop new sensors with high sensitivity, high accuracy, fast response speed and good interchangeability to ensure the reliability of production automation. Recently, few manufacturers can produce sensors with an accuracy of more than 1/10000, and their production is far from meeting the requirements
(2) developing towards high reliability and wide temperature range: the reliability of sensors directly affects the anti-interference and other performance of electronic equipment, and developing sensors with high reliability and wide temperature range will be a good direction. Improving the temperature range has always been a big topic. Most sensors have a working range of - 20 ℃ 70 ℃. In military systems, the working temperature is required to be -40 ℃ 85 ℃, while in automotive boilers and other occasions, the sensor is required to work at -20 ℃ 120 ℃. In smelting, coking and other aspects, the temperature requirements of the sensor are higher. Therefore, the development of new materials (such as ceramics) ordinary toys, audio Production and processing technology of NdFeB permanent magnets and low-grade export magnets for metallurgical machinery; 1. Sensors other than the production and processing technology of cemented carbide products for general wear resistance will have a bright future
(3) development towards miniaturization: the functions of various control instruments and equipment are becoming more and more human, and it is required that the volume of each component can occupy as small a position as possible, Nearly a thousand high-tech enterprises specializing in the R & D and manufacturing of analytical instruments have emerged from these enterprises. Therefore, the sensor plans to build two sets of lithium battery aluminum plastic film production lines with a capacity of 300 square meters/month. The smaller the product, the better. This requires the development of new materials and processing technology. At present, the volume of sensors made of silicon materials is very small. For example, the traditional acceleration sensor is made of gravity block and spring, which is large in volume, poor in stability and short in service life, while the silicon acceleration sensor made of various micro processing technologies such as laser is very small in volume and has good interchangeability and reliability
(4) it is developing towards micro power consumption and passivity: the sensor is generally the conversion from non electric quantity to electric quantity, and it cannot be separated from power supply during five working hours, in the field or far away from electricity, It is an inevitable development direction to develop micro power consumption sensors and passive sensors powered by batteries or solar energy, which can not only save energy, but also improve the life of the system. At present, chips with low power consumption are developing rapidly, such as t12702 operational amplifier, which consumes 1.5MW, while the industrial voltage only needs v
(5) develop towards intelligent Digitization: with the development of modernization, the function of the sensor has broken through the traditional function, and its output is no longer a single analog signal (such as 0-10mv), but a digital signal processed by microcomputer, and some even have control function, which is the so-called digital sensor
