The Alicat Scientific PC and PCR series pressure controllers provide precise control of absolute or gauge pressure of process gases and liquids. Utilizing the same valves used in Alicat's mass flow controller line results in fast and accurate pressure control. With a fully functional digital display and a host of other standard features, Alicat's PC and PCR series line of pressure controllers are a feature rich solution for applications requiring precise pressure control.
The Alicat PC and PCR series is available in gauge and absolute ranges to 500 psi as well as differential ranges to 100 psi. Using a modified PID closed loop control and a proportional control on each valve results in a total full scale accuracy of ± 0.25% across all ranges, making the PC and PCR series much more precise than standard manual regulator pressure controllers. The PCR series includes a Rolamite low-pressure drop valve for high flow applications. With a 50ms response time, the Alicat PC and PCR series pressure controllers are ideal for a variety of applications in which precise and stable pressure control are a requirement.
The Alicat Scientific PC and PCR series pressure controllers are available with a variety of digital and analog input and output options allowing users to tailor the pressure controller to their application. Rugged and dependable, PC and PCR series controllers require very low power to operate and when used properly require minimal maintenance.
