Electric Valve Intelligent Manual Locator
ZXQ98 (hereinafter referred to as locator) can equip with the potentiometer or standard current feedback electric actuator, supporting various valve for accurate positioning operation, show intuitionally, convenient operation. It is widely used in metallurgical, petrochemical industry, building materials, machinery, cement, pharmacy, food, wine, papermaking and other industry electric valve accurate control.
Free choice, auto/manual way,
Unique TOYI input signal filter algorithm, effective in normal times the divisor input signal range of peak pulse signal, and maintain eight times/sec sampling speed and technical index accuracy,
Parameter display, at the same time, show the valve position measurements, setting, convenient observation and debugging,
With simple, automatic calibration, electronic brake, frequently, test and control functions,
Convenient positioning accuracy adjustment, ensuring positioning stably, achieve the function of settling a matter at one go.
, positive/reaction can be set and output upper limit and lower limit function.
