Multi-Turn Electric Actuator

1. Main Features:
* Using the super large scale integrated chips, a good many function, high precision. * Designing with mechatronics, nice contour and light weight.

* Available special pressure sensor can be used to measure the torque value of the output shaft. Raising the testing accuracy of the torque value and enable display and monitor alternately. Torque tripped, stalled can be shown and alarmed.
* Using hall sensor as the position transducer, detect the position, the pulse signals can be processed. Locating accuracy of the valve position is up to 1.0%.
* By using the non-intrusive infra-red setting tool set up the functions and parameters, adjusting and operating the actuator in local.
* Display in symbol and operating in order and it is easy to understand, view, and operational
