Electric controller with integrated pressure transformer and controller functions in a compact and simple package

A pressure controller integrated with a pressure sensor, controller and motor in a compact package.

Senses any deviation in current pressure using preset control pressures. The controller turns the operating axis in the relevant direction needed to eliminate the deviation. The valve connected to the operating axis opens and closes in changing the flow rate and stops the open/close operation when the predetermined pressure has been achieved.

The control action combined with the proportional and derivative actions is dedicated to constantly monitoring and controlling the pressure. This then means that the method of control does not depend on how open a valve or other components are, thereby not requiring a potentiometer for use in signaling how open it is, and allowing the controller to have less potential problems in operation.

Revolution speed of the operating axis features unique fractional deviation speed operation, thus realizing stable positioning without overshooting.


The cost of instrumentation can be reduced as neither a transformer or a regulator are required for the pressure and flow rate. Control can be established by merely directly inputting the process values needed in that control.

Mechanical work merely involves linking the operating axis of the device to the operating end such as a butterfly valve and wiring in the input pressure. No other electrical work required than wiring the motor to the power supply.

The controller has a wide variety of adjustable functions for speed differences when opening/closing, operating speed, proportional speed action band, and dead zone and others, and accordingly provides stable control performance without overshooting or hunting.

The controller has an extraordinary long life cycle as it is equipped with robust gears as well as a non-contact motor drive relay (Solid State Relay, SSR).

The appropriate model can be selected from the various models available depending on the required functionality. The appropriate pressure-sensitive parts can be selected depending on the input specifications such as pressure and flow rate, thus allowing a variety of combinations.
