Overview
Overview
The πPC Pressure Controller is a self-contained, compact, closed-loop electronic pressure control system designed for a wide range of pressure and flow conditions. It contains a capacitance manometer, normally closed or normally open control valve and closed-loop control electronics. The πPC is available in either an upstream or downstream pressure control configuration, with either digital (DeviceNet or RS-485) or analog I/O and its Ethernet setup and diagnostics capabilities, the πPC is easily integrated into the process tool.
