Pressure Controllers for Flowing Processes
Use pressure controllers when gas is flowing through a process. They control absolute, gauge, or differential pressures, and can measure in-line pressures or be plumbed to measure process pressures at any point.
Absolute and Gauge Pressure Controllers
PC–Series Pressure Controllers control pressure without introducing a dead-ended obstruction into the system.
PCS–Series Anti-Corrosive Pressure Controllers control pressure of any gas, including corrosive gases.
Remote Sensing Absolute and Gauge Pressure Controllers
PC3–Series Pressure Controllers with Remote Sensing control pressure exactly where needed by physically isolating the pressure sensor from the valve and flow path.
PC3S–Series Anti-Corrosive Pressure Controllers with Remote Sensing control pressure at any process point for any gas, including select corrosive gases.
Differential Pressure Controllers
PCS–Series Anti-Corrosive Differential Pressure Controllers control the pressure between two process points for any gas, including select corrosive gases.
Use Alicat pressure controllers to rapidly measure and control absolute, gauge, or differential pressure. Pressure controllers are accurate to ±0.25% of full scale, with a measurement range from 0.01-100% of full scale.
Absolute pressure can be measured up to 3,000 PSIA and as low as 15 PSIA before turndown. Gauge pressure instruments measure as low as 2 inH₂O and can measure negative gauge pressure to -15 PSIG.
Common configurations including anti-corrosive are available, as are electronic pressure controllers and controllers for vacuum processes.
