PC3S–Series: Anti-Corrosive Absolute and Gauge Pressure Controllers with Remote Sensing

PC3S–Series Anti-Corrosive Absolute and Gauge Pressure Controllers with Remote Sensing control the absolute or gauge pressure at any point in your system with a remote sense port – for all non-corrosive gases, select corrosive gases, and a variety of liquids.
  • Aggressive gas compatibility. Wetted materials compatible with 32+ pure corrosive gases and most refrigerant gases, in addition to all non-corrosive gases and a variety of liquids.
  • Fast & accurate. Custom valve sizing and PID tuning ensure controllers reach pressure setpoints in milliseconds and maintain control with NIST-traceable accuracy to ±0.125% of full scale.
  • Versatile control. Control absolute or gauge pressure anywhere in your system, including areas where you cannot easily install a full pressure controller. Plumb the pressure port downstream for pressure or vacuum control, or upstream for back pressure control.
  • Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, PROFIBUS, PROFINET, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.

*Negative gauge pressure readings (to –15 PSIG) can also be included in gauge ranges.

Absolute/gauge PC3S-Series operating conditions
  • Compatible fluids: All non-corrosive gases, select corrosive gases, and chemically compatible liquids
  • Operating temperature: –10°C to +60°C
  • Burst pressure: 3x full scale (1.5x full scale for ≥ 500 PSI devices)
Device Ranges & Full Specs

Gauge devices are custom ranged from 5 PSIG full scale to 3,000 PSIG full scale, and absolute devices are custom ranged from 15 PSIA full scale to 3,000 PSIA full scale. Most devices have a controllable range of 0.5% to 100% of full scale (valve dependent).

Device Features
Included with each device
  • User changeable units of measurement: Change the unit of measurement for pressure from our extensive list of engineering units.
  • Monochrome backlit LCD with integrated touchpad: Easily read measurements using the backlit display and control configurations with the user-friendly integrated touchpad.
  • User adjustable setpoint ramping & limits: Configurable ramp rates allow the process variable to be controlled as fast or as slow as desired, and configurable setpoint limits protect processes from inadvertent setpoint changes.
  • Valve close override and valve open override: Utilize alarms to quickly vent your system or stop all flow as needed.

Valve options & PID tuning

Your pressure controller may be customized with one of the following valving options to ensure optimal performance under your expected process conditions.

  • PC3 – small proportional control valve for flow ranges of 20 SLPM and below
  • PC3 with PCA designation – high-performance proportional control valve used for applications with higher pressures
  • PCH3 – hammerhead configuration, which pairs two small valves working side-by-side as one valve
  • PCR3 – nearly frictionless large Rolamite proportional valve for flow rates of 50 SLPM and above

Note: Certain gases (including SO2, and Cl2require PC with PCA designation.

Custom PID valve tuning ensures maximum performance for your specific process conditions.

Optional Accessories
