PC–Series: Absolute and Gauge Pressure Controllers

PC–Series Absolute and Gauge Pressure Controllers control absolute pressure or gauge pressure of all non-corrosive gases.
  • 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. Maintain absolute pressure (referenced to vacuum) or gauge pressure (referenced to local barometric pressure) immediately upon powering up, with readings displayed in your choice of engineering units.
  • 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.

Quick Specs
Absolute/gauge PC-Series performance (most products)
  • Available full scale ranges:
    • Absolute: max 0–3000 PSIA; min 0–15 PSIA
    • Gauge: max 0–3000 PSIG; min 0–0.07 PSIG (2 inH₂O)*
  • Steady state control range: 0.01% – 100% of full scale
  • Standard accuracy calibration, NIST-traceable: ±0.25% of full scale
  • Optional high-accuracy calibration, NIST-traceable: ±0.125% of full scale
  • Repeatability: 0.08% of full scale
  • Typical control response time: as fast as 30 ms
  • Warm-up time: <1 s

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

Absolute/gauge PC-Series operating conditions
  • Compatible gases: All non-corrosive gases
  • Operating temperature: –10°C to +60°C
  • Burst pressure: 3x full scale (1.5x full scale for 500 to 3000 PSI devices)
Device Ranges & Full Specs

Gauge devices are custom ranged from 2 inH₂O 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 0.01% 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.

  • PC – small proportional control valve for flow ranges below 20 slpm
  • PC with PCA designation – high-performance proportional control valve used for applications with higher pressures
  • PCP – small proportional control valve with the largest orifice (not available for corrosive configurations)
  • PCH – hammerhead configuration, which pairs two small valves working side-by-side as one valve
  • PCR – nearly frictionless large Rolamite proportional valve for flow rates of 20 slpm and above

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

Optional Accessories
Accessories | Sold separately
  • Process port fittings and filters
  • Power supplies
  • Communications cables and conversion cables
  • BB3 and BB9 multi-drop breakout boxes
