Alicat’s PCD dual-valve pressure controller is a fast, precise and repeatable pressure control instrument specifically designed for closed volumes. It uses intake and exhaust valves that are independently controlled to obtain quick and stable pressure control within a closed or dead headed system.
The PCD controller features proprietary control software and electronics that enable it to input process gas into a chamber. The unit operates by utilizing a modified PID loop control that allows it to control each valve while enabling only one valve to open at a time. Through this setup, the unit reaches a setpoint quickly and effectively and keeps the gas venting to an absolute minimum.
The PCD pressure controller is used in a wide range of industries, ranging from biopharmaceutical testing to semiconductor manufacturing.
