Overview
The new generation of intelligent RQMⅢ series electric actuators can be set, checked and queried quickly and non-invasively through an independent setter. The actuator adopts graphical dot-matrix LCD display to display torque, valve position, limit setting and other working status and alarm in Chinese, numbers and graphics, as shown in Figure 1-1, which greatly facilitates the user’s operation and use. The actuator has automatic protection function and flak proof function. Even in the dangerous area without opening the working actuator electric box cover can be adjusted, fault diagnosis. The field bus communication card can be used to form a fully distributed computer cooperative working system to realize remote communication, remote collection, remote diagnosis and maintenance. Because of its advanced nature, reliability and convenient operation, it is welcomed by the majority of users and widely used in petroleum, electric power, metallurgy, water treatment and other industries.
