* Mechatronics design, small size, light weight.
* Use a professional pressure sensor to measure the torque value of the output shaft, thus improving the accuracy of the torque measurement, the error rate ≤ 5% and can be dynamically monitored, showed torque, stall can alarm
IA, IM series of electric devices. Is the world's leading smart products. Advanced
large-scale digital integrated chip, professional digital torque sensor
and digital displacement sensor, full Chinese menu operation and
display, mechatronic structure design, created its perfect function,
excellent performance, lightweight and beautiful, easy to debug, Easy to
operate. And the opening and closing pieces
supporting the composition of the implementation of the unit, used in
power plants, petroleum, steel, chemicals, pipelines, sewage treatment
and other automatic control systems, both to meet the frequent
regulation and control, but also to meet the requirements of
intermittent control.
The implementation of this product code and name of the standard: Q / ZTK 01-2009 "electric device"
1, the main features of electric devices:
* The use of large-scale digital integrated chip, powerful, high accuracy level.
* Mechatronics design, small size, light weight.
*
The use of a professional pressure sensor to measure the torque value
of the output shaft, thus increasing the accuracy of the torque
measurement, error rate ≤ 5% and can be dynamically monitored, displayed
torque, stall alarm.
*
The displacement sensor uses the Hall sensor, and digitally processes
the pulse signal, so the basic error of the valve positioning accuracy
is 1 level accuracy.
*
Electric device function, parameter setting, commissioning and on-site
electric operation are set by hand-held infrared remote control, without
opening the cover.
* Full Chinese and character display, menu operation, intuitive and clear, easy to learn, easy to understand, easy to operate.
