Solar wireless electric actuators, it is just the use of new energy power supply of the new product, solve the reasons due to the distance of power supply is not convenient, spare to use energy increased new opportunity for China's environmental protection and energy saving, electric actuator is introduced in the UK ROTORK (ROM toelke) technology, A, M series electric actuators, on the basis of using today's most advanced large scale digital integrated circuit development into A new generation of intelligent, digital, full Chinese menu display, remote control electric actuators. A new generation of intelligent electric actuators can be quickly programmed, checked, and searched for non-invasively through an independent settler. The actuator adopts graphic dot matrix liquid crystal display to display the torque, valve position, limit setting and other working status and alarm of the actuator in the form of Chinese, figures and graphics. The user's operation is greatly facilitated. The actuator has the function of automatic protection and flameproof, and it can adjust, check parameters and diagnose faults without opening the electrical box cover of the actuator in work even in the danger area. The fieldbus communication card can be used to form a fully distributed computer cooperative work system, realizing remote data acquisition, remote communication, remote diagnosis and maintenance. It has been widely used in petroleum, electric power, metallurgy and water treatment industries because of its advanced, reliable and convenient operation.
