2019-09-25

With the development of smart meter technology, microelectronics technology is widely used in traditional meters, greatly improving the functions and performance of meters. The valve positioner is the main accessory of the regulating valve. It is usually used in conjunction with the pneumatic regulating valve. It receives the output signal of the regulator, and then uses its output signal to control the pneumatic regulating valve. When the regulating valve is actuated, the displacement of the valve stem passes through The mechanical device is fed back to the valve positioner, and the valve position status is transmitted to the upper system through electrical signals.

When the manual operator, PID regulator, DCS or PLC adopts pneumatic control valve to complete the process control, it is necessary to convert the electrical signal into a pneumatic signal to control the work of the pneumatic actuator. There are electrical converters and electrical valve positioners that meet this function, but because the structures and functions of these two meters are different, there are also differences in the use of electrical converters and electrical valve positioners.
