burkert 00155369寶德定位器閥門定位器是控制閥的主要附件.它將閥桿位移信號作為輸入的反饋測量信號,以控制器輸 出信號作為設定信號,進行比較,當兩者有偏差時,改變其到執行機構的輸出信號,使執行機構動作,建立了閥桿位移倍與控制器輸出信號之間的一一對應關系。因此,閥門定位器組成以閥桿位移為測量信號,以控制器輸出為設定信號的反饋控制系統。該控制系統的操縱變量是閥門定位器去執行機構的輸出信號。閥門定位器的分類 閥六定位器按輸入信號分為氣動閥門定位器和電氣閥門定位器。
Valve positioner is the main control valve accessories. It will stem the displacement feedback signal as the input signals, as set in the controller output signal, comparing, when there is deviation, change of its output signal to the actuator, the actuator movement, the valve stem is established displacement times and one to one correspondence relation between the controller output signal. Therefore, the valve positioner consists of stem displacement as the measurement signal, and the controller outputs the feedback control system that sets the signal. The control variable of the control system is the valve locator to execute the output signal of the mechanism. Valve positioner classifier valves are divided into pneumatic valve positioner and electrical valve positioner according to input signal.
