Alicat PC - Pressure Controller

  • Available for gauge and absolute pressures up to 3000 PSI / 207 Bar
  • Differential pressures up to 100 PSI / 7 Bar
  • 50-100 ms speed of response stills upstream fluctuations
  • Up to ±0.125% of full scale accuracy
  • No warm-up time required

Fast-responding pressure, vacuum or differential control for flowing processes

Alicat PC 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.

The PC series pressure controller is repeatable and accurate with calibrations up to +/- 0.125% of full scale accuracy. Every PC series controller has a 1/8” NPT female connection and are typically suited to low flow pressure applications.

Every Alicat pressure controller 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 0-5Vdc. Modbus-RTU, available over RS-232 or RS-485 and PROFIBUS protocols are available as an option.

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