Electric Actuator

 IA, IM series of electric devices. Is the world's top intelligent products. Advanced digital integrated chip, professional digital torque sensor and digital displacement sensor, the whole Chinese menu operation and display, mechanical and electrical integration of the structural design, creating its perfect function, excellent performance, lightweight and beautiful, simple debugging, Easy to operate. It is used in automatic control system such as power station, oil, steel, chemical industry, oil pipeline, sewage treatment and so on. It can meet the requirement of frequent regulation and control and meet the requirements of intermittent control. 
This product is the implementation of the standard code and name: Q / ZTK 01-2009 "electric device" 

1, The Main Features Of Electric Devices:
* Large-scale digital integrated chip, powerful, high precision level. 
* Mechatronic design, small size, light weight. 
* Using a professional pressure sensor to measure the torque value of the output shaft, thus improving the accuracy of the torque measurement, the error rate of ≤ 5% and dynamic monitoring, showing the torque, stall can be alarm. 
* Displacement sensor using Hall sensor, and pulse signal digital quantization, so the valve positioning accuracy of the basic error of a precision. 
* The function of the electric device, parameter setting, commissioning and on-site electric operation are set by hand-held infrared remote control without opening the lid. 
* All Chinese and character display, menu type operation, intuitive and clear, easy to learn, easy to understand, easy to operate.
