PC3 Series Pressure Controllers

:

The PC3 Series pressure controller is designed to change the flow to allow the control of pressure at

some point away from the body of the controller. This is most helpful when it is necessary to mount

pneumatic components such as valves, fittings or flow meters that introduce significant pressure drop

between pressure controller body and the point where pressure control is necessary. To accomplish
this, the PC3 has an external sensing port to which the pressure at the location where pressure is to be
controlled is piped back to the pressure sensor in the controller.
