It is used to detect, record and display changes in chemical process parameters, realize the monitoring of the production process and provide information to the control system. Such as temperature, pressure, flow rate and liquid level (see figure).
**Analytical instrument, mainly used to detect, record and display the changes in physical parameters (such as concentration, acidity, density, etc.) and components of the chemical process, is the direct information to monitor and control the production process.
Control instrument, used to keep the chemical process parameters within the specified range according to a certain accuracy, or make the parameters change according to a certain law, so as to achieve the control of the production process.

Anonymous users2024-02-05During the "Twelfth Five-Year Plan" period, China's instrumentation market capacity is very large, and the application field is broad, but the demand for the application field is relatively concentrated, and the application requirements are mainly in the fields of iron and steel, coal chemical industry, petroleum, medicine, light industry and other industrial sectors.
In addition to thousands of new projects in these industrial sectors that need to be equipped with a large number of automated instruments and control systems, there are also tens of thousands of enterprises that need to carry out technological transformation, for which the demand for replacing old instruments or parts is extremely huge.
1. Environmental protection instrumentationEnvironmental protection instrumentation is mainly used in environmental quality monitoring and pollution source monitoring. According to China's specific national conditions, environmental protection mainly solves the two strategic and overall environmental ecological pollution problems of China's water environment and atmospheric environment. With energy saving, consumption reduction, emission reduction and low-carbon economy have become long-term national policies.
2. Electrical instrumentation In the State Grid Corporation of China, it is necessary to vigorously promote the UHV power grid as the leader, the coordinated development of power grids at all levels, and the principle of improving the smart grid, and at the same time, it is also clear that the construction of power user electricity information collection system is an important part of China's smart grid construction, and the construction of smart grid has developed gradually. The construction of power grid is a global behavior, a long-term, gradual rigid market, and a major development opportunity for the electrical instrumentation industry.
3. Industrial automation instruments Industrial automation instruments focus on the development of main control system devices based on fieldbus technology, intelligent instruments, special and special automation instruments. From the perspective of market demand, China's industrial automation market demand is booming. According to the China Instrument and Control Association, by the end of the 11th Five-Year Plan, the market demand for industrial automation will exceed 100 billion yuan.
In addition, with the great increase in the country's attention to people's livelihood, some needs related to people's livelihood have also been put on the agenda, and new requirements and market demand for instrumentation have also been proposed.

The automated manufacturing system includes rigid manufacturing and flexible manufacturing, and the meaning of "rigid" means that the production line can only produce a certain type of product or a certain type of product with a similar production process, which is manifested as the singleness of the production product. Rigid manufacturing includes combined machine tools, special machine tools, rigid automatic production lines, etc. >>>More
The hump is the main feature of the marshalling station, it is a small hill built on the ground like the shape of the back of a camel's hump, designed with an appropriate slope, the railway is laid on it, and the potential energy generated by the gravity of the vehicle and the slope of the hump is supplemented by the locomotive thrust to dismantle the train is a kind of shunting equipment, which is a main method of dismantling the train in the marshalling station. When carrying out the hump shunting operation, the train is pushed to the hump by the shunting machine first, and when the front car group (or vehicle) is close to the peak, lift the hook, then you can use the gravity of the vehicle itself, automatically slip down the slope to the predetermined line of the marshalling yard, so that the efficiency of the shunting operation can be greatly improved. The camel bee is generally located at the head of the shunting yard, which is suitable for the dismantling operation of the train. >>>More
