YT-3301 Smart Valve Positioner
YT-3301 Smart positioner supplies remote functions and higher liabilities in high temperature and vibration environment.
Description
1.product introduction
   YT-3301 Smart positioner supplies remote functions and higher liabilities in high temperature and vibration environment.  Smart Valve Positioner accurately controls valve stroke, according to input signal of 4-20mA, which is being input from the controller. In addition, built-in micro-processing operator optimizes the positioner's performance and provides unique functions such as Auto calibration, PID control, Alarm, and Hart protocol.
