Baratron® Capacitance Manometer Technology

The PPCA utilizes leading Baratron® capacitance manometer technology for pressure measurement from MKS Instruments. It is integrated along with a proportioning control valve and the latest in control electronics providing fast and accurate pressure control with critical flow monitoring as a system diagnostic. The PPCA can be configured for 10 to 1000 Torr Full Scale pressure with a control range from 5 to 100% of Full Scale. This configurability makes the device suitable for transport chamber pressure control, critical backside wafer pressure control as well as run-vent pressure control applications. The control valve can be configured for Full Scale flow rates from 5 to 5000 sccm Full Scale depending on process conditions.

DeviceNet™ or EtherCAT® I/O

The PPCA is available with either digital (DeviceNet™ or EtherCAT®) I/O allowing for straightforward integration into new or retrofit applications. In-situ tuning and component diagnostics are enhanced through the device’s micro USB user interface accessible via virtually any PC with a web browser.
