Series intelligent rotok electric actuator is the world's top intelligent products. Advanced very large scale digital integrated chip, professional digital torque sensor and digital displacement sensor, Chinese menu operation and display, mechanical and electrical integration structure design, made its perfect function, excellent performance, lightweight and beautiful, simple debugging, easy to operate. It can be used in the automatic control system of power station, petroleum, steel, chemical industry, oil pipeline, sewage treatment and so on. (gate valve, globe valve, diaphragm valve, etc.)
BRIA, BRIM series multi-turn intelligent electric actuator is driven by three-phase servo motor, which drives hollow output shaft to rotate through worm gear and worm gear deceleration. In the gearbox, a manual/automatic switching mechanism is provided. When the switch handle is in the manual position, operate the hand wheel and drive the hollow output shaft to rotate through the clutch. When the actuator is electrically operated, the manual/automatic switching mechanism falls back automatically, the clutch meshes with the worm wheel, and the hollow output shaft is driven by the three-phase motor. At the same time, a torque sensor is installed on the motor drive worm shaft. The stroke is transmitted to the position sensor through bevel gear engagement on the hollow output shaft.
Many rotary ROM toelke intelligent electric actuator, the intelligent controller to accept standard analog current control signal or switch control signal, and at the same time, compared with the position of the valve position sensor signal, the output shaft of the actuator position in relative position, and the input signal to complete the positioning control, and can according to the control or events signal interlocking control, two line aimed at a preset position control system, unless incurred during the process of running the actuator output shaft torque value is greater than the rated torque or set torque value, otherwise intelligent controller of the actuator will meet the requirements of control system, the correct instruction, trigger three-phase solid state relay, Connect the motor to three-phase power supply and drive the actuator to run normally.
The multi-turn intelligent rotok electric actuator is designed in a non-invasive way. The parameters and functions of the actuator can be modified or configured by the hand-held remote control.

1. Main features of intelligent rotok electric actuator
* large scale digital integrated chip, powerful, high precision level.
* mechanical and electrical integration design, small size, light weight.
* professional pressure sensor is adopted to measure torque value of output shaft, so the accuracy of torque measurement value is improved, the error rate is ≤5%, and it can be dynamically monitored and displayed
Over torque, block turn can alarm.
* displacement sensor adopts hall sensor and digital quantization processing of pulse signal, so the basic error of valve positioning accuracy is level 1 accuracy.
* the function, parameter setting, debugging and field electric operation of the actuator are set through the hand-held infrared remote control, without opening the box cover.
* Chinese and characters display, menu operation, intuitive, easy to learn, easy to understand, easy to operate.
