Siemens Positioner working principle:
6DR5015-0EN00-0AA0 Siemens positioner relies on the collaboration of the processor, the sensor and the piezoelectric valve. The processor receives the feedback signal from the valve position sensor and compares it with the 4 to 20mA signal. According to the comparison result, the processor calculates the control instruction, and adjusts the action of actuator through the piezoelectric valve to control the opening and closing of the valve.
