China must pay great attention to the sensor industry

In modern industrial equipment, sensors and measuring instruments are an indispensable part of the reason, but also from the following two aspects: the traditional industrial equipment such as adding the necessary sensors, equipped with precision measuring parts ( accessories ) , then Its function and accuracy can be improved, user-friendly operation and maintenance, security level can also be improved, equipment can be added value , industrial equipment as part of the control system of the automation system or as part of the automation system must be able to interact with the three parts of the automation system ( detection, control , Execution ) is compatible or provides an interface to integrate it into an organic whole, whether it is a stand-alone automation or as part of a large-scale automation device, making the use of the industrial equipment to expand. In summary, adding sensors and measuring instruments, measuring instruments or providing interfaces as industrial equipment itself is a necessary condition for the upgrading of traditional equipment.

The sensor is a device that converts non-electrical energy into electrical signals. In the case of an analog circuit, the detection instrument generally includes a sensor, a detection point sampling device, and an amplifier ( for anti-jamming processing and signal transmission ) , and of course, the power supply and the field. Display part ( optional ) , the electrical signal is generally divided into two kinds: continuous and discrete. Actually, it can be divided into analog quantity, switch quantity, pulse quantity, etc. The analog signal transmission adopts unified signal (4~20mADC, etc. ) . In the digitization process, the detection instrument changes greatly. After several stages, ASIC specific integrated circuits are used more recently, and sensors and microprocessors and network interfaces are encapsulated in one device to complete information acquisition, processing, transmission, storage, and the like. Features. Often referred to as a transmitter in the automation instrument, such as temperature transmitters, pressure transmitters. Because sensors are used in all walks of life, coupled with the rapid development of household appliances, automobiles, and information industries over the years, the demand for sensors has greatly increased. Therefore, the sensor manufacturing industry has developed rapidly, forming an independent industry, which has driven the industrial equipment. In particular, the development of semiconductors and equipment manufacturing industry, so China must pay special attention to the sensor industry.
