GPCA General Purpose Pressure Controllers
Model: GPCA

Overview
Overview
The GPCA is a metal-sealed pressure controller well suited for a wide variety of applications requiring pressure control capability from 500 Torr to 100 psi. It incorporates the latest in digital flow control electronics along with a well proven, thermally stable pressure sensor and mechanical design. The GPCA digitally controlled pressure controller is available with either digital I/O (EtherCAT®, DeviceNet™ or RS485). The digital control electronics utilize the latest in MKS control algorithms providing fast and repeatable response to set point throughout the device control range. Typical response times are less than 1 second dependent on installation conditions. Included is a digital calibration that yields 1% of set point accuracy. The GPCA with 4 VCR® fittings is designed with a 1.125 inch (28.6 mm) width and standard 4.88 inch (124 mm overall) length allowing it to fit in standard gas systems. It is also available with 1.125 inch (38.6 mm) IGS compatible c-seal and w-seal configurations.
