1 product overview

1.1 overview

Process control is the abbreviation of automatic control of production process, which is an important part of automation technology. Usually refers to the production process of oil, chemical, electric power, metallurgy, light industry, building materials, nuclear energy, etc. In modern industrial production process, process control technology is to achieve optimal technical and economic indicators, improve the economic benefit and labor productivity, improve working conditions, protect the ecological environment plays a more and more important role.

In process industry automation and information system as the main line, the key technology and equipment system we design and production process control professional laboratory comprehensive practice teaching equipment, set up the theme of the major laboratory engineering practice base.

This training unit design is reasonable, the versatility, not only can satisfy this, industrial automation, automatic control and so on the specialized subject of professional courses related to the requirement of experimental teaching, but also suitable for graduate students on topics in the research and development.
