Electronic Pressure Controller is a precision device that maintains the electric and pneumatic pressure at a fixed level, by making the use of a closed-loop control. It is made to control the flow or pressure and can also replace mass flow controllers as well as mechanical control systems. It offers higher pressures and ensures enhanced robustness and flexibility than previous. The precise operation of this controller needs a DC power supply as well as set-point signal. It also enables for output pressures that is considerably greater than the pressure transducers. Electronic Pressure Controller is operated by making use of a push valve as well as a vent valve for maintaining the outlet pressure at the fixed set-point. Electronic Pressure Controller can monitor the output pressure with its analog controller that aid in the timing adjustment.
