PC–Differential Pressure Controllers
Fast-responding differential pressure control.
Order Directly from Alicat
Measure the differential pressure between any two points in your process, and control flow at a different point to ensure the pressure differential remains constant. The two process ports connect to opposite sides of the differential pressure sensor; positive readings denote higher pressure at the left (upstream) process port, and negative readings denote higher pressure at the right (downstream) port. We’ll use your application parameters to customize your valve and PID tuning to ensure that your controller delivers fast and stable control.
- Fast & Accurate. Very fast valves and PID control algorithms hit pressure setpoints in milliseconds with NIST-traceable accuracy.
- Connected. Easy integration into your digital industrial network with EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP) or serial communications options.
- Versatile. Plumb the two pressure ports wherever you need to measure and control the pressure difference. Use the instrument as a gauge pressure controller by leaving the downstream port open to atmosphere.
