Alicat PCR series of pressure controller maintain precise control in your absolute, gauge of differential pressure applications. Additionally they can be configured for either a vacuum pressure or back pressure control.
PCR series maintain pressure stability and accuracy at high flow rates up to 3000 SLPM. Alicat is the world’s only manufacturer of near-frictionless Rolamite valves for precise control of high-rate fluid flows. Proprietary orifice patterns enable us to customize a Rolamite to satisfy your application and performance requirements.

The PCR series pressure controller is repeatable and accurate with calibrations up to +/- 0.125% of full scale accuracy. Every PCR series controller has a 3/4” NPT female connection and are typically suited to higher flow applications where the flow rates exceed 20 LPM.

Every device has a 200:1 turndown ratio with many standard pressure ranges available, standard pressure units include PSIA, PSIG, mmHG, inHG, inH2O, mBar, Atm, Torr and kPa.

The digital pressure controller features a local LCD screen and push button user interface to change process variables. A colour TFT display is also an option to.

RS-232 communications are standard as well as an analogue output signal such as 0 – 5 VDC. Modbus-RTU, available over RS-232 or RS-485 and PROFIBUS protocols are also availble.

Every Alicat device is backed by the manufactures limited life time warranty and ships with a NIST traceable calibration certificate.

CSA/ATEX area classification is optional. Ex nA IIC, T4 Tamb. -40°C ≤ Ta ≤ +50°C
