Rotork multi turn electric actuator
Description
1. Main features of electric device:
* it adopts large-scale digital integrated chip with powerful function and high precision level.
* Mechatronics design, small size and light weight.
* the experienced pressure sensor is used to measure the torque value of the output shaft, so the accuracy of the torque measurement value is improved, the error rate is ≤ 5%, and the over torque can be dynamically monitored, displayed, locked rotor can be alarmed.
* the displacement sensor adopts Hall sensor and digitally quantizes the pulse signal, so the basic error of valve positioning accuracy is level 1 accuracy.
* the function, parameter setting, commissioning and on-site electric operation of the actuator are set through the handheld infrared remote control without opening the box cover.
* full Chinese and character display, menu operation, intuitive and clear, easy to learn, understand and operate.
