Alicat Scientific PCD | Dual-Valve Pressure Controller | 0.07-3,000 PSI, 30 ms response
The Alicat Scientific PCD is a dual-valve pressure controller for closed or dead-ended volumes, with inlet and exhaust valves giving 30 ms control response over 0.07 to 3,000 PSI full scale. It controls absolute, gauge or differential pressure, in positive pressure or vacuum, with steady control from 0.01 to 100% of full scale. Leak testing and pressure decay rigs are typical uses.
Key features
- Inlet and exhaust valves for closed volumes
- Positive pressure or vacuum
- 10,000:1 turndown
- Range codes from 10 Torr A to 3,000 PSIG listed
