With the in-depth development of China's economy, our country's demand for the chemical industry is more and more in-depth. The petroleum and chemical industry is developing in the direction of deep processing, and the fine chemical industry is also developing rapidly. The fine chemical industry has many kinds of products, high added value, wide use and great relevance, involving many industries and high-tech industries.

Fine chemical production generally takes chemicals with certain corrosivity, toxicity, flammability and explosiveness as process medium, so it is very dangerous in the production process. These are the reasons that make the production process of fine chemical industry difficult to control, and also make it unable to achieve a higher level of integrated automation. Therefore, the requirements for the sensor are more strict, and the precise measurement is needed to ensure its efficient and stable production.

At present, the sensor has realized digital excitation, and uses can field bus on the transmitter, and uses sensor embedded technology as its main technology.

At the same time, with the widespread use of intelligent sensors in fine chemical industry, lodinson believes that the development of sensors in the future will present the following characteristics: intelligent, integrated, miniaturized, standardized and extensive.

Intellectualization: with the deepening of research and development, sensors in the future will develop towards the functions of automatic compensation, communication, self diagnosis and logical judgment.
Integration: the sensor is integrated with other sensors to form a measurement and control system.
Miniaturization: the future sensor miniaturization is the demand of many working environments, and also has a very broad market space.
Standardization: future sensor design and manufacturing will form a certain industry process.
Generalization: in the future, sensors will be widely used in petroleum, chemical and other process work.

According to the above development trend and combined with the different needs of customers in the fine chemical industry, lotingson constantly improves the products and carries out product iteration. At the same time, Rodinson provides customers with perfect sensor selection and use scheme according to the characteristics of fine chemical industry. By analyzing the application environment and process characteristics of major customers, the following three key points of sensor use are summarized.

In terms of the selection basis, the order is as follows: (1) the property index of the tested medium; (2) saving money; (3) being convenient for installation and maintenance. At the same time, for the medium with high viscosity, easy crystallization and strong corrosion, the isolation type must be selected, and whether the medium will cause metal corrosion of the capsule must be considered. In addition, the selection should be based on the temperature of the measured medium. For 200 ~ 400 ℃, high temperature type should be selected. The working pressure level is also one of the main basis for type selection. The pressure rating of the transmitter should be in accordance with the application. Similarly, the corrosivity of the tested medium should also be considered in the selection of common transmitter.

In the future, with the in-depth development of China's fine chemical industry, Lotensin will develop more intelligent sensors for fine chemical industry in the future, so as to help China's vigorous development in fine chemical industry.
