PC–Series: Absolute and Gauge Pressure Controllers
Product description:
  • 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.
     

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)

 

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.

  • Optional integrated potentiometer control: Use the integrated potentiometer to adjust setpoints with the simple turn of a knob.

 

Build and performance options

  • Communication protocols: Analog, RS–232, RS–485, DeviceNet, EtherCAT, EtherNet/IP, Modbus RTU or TCP/IP, PROFIBUS, PROFINET
  • Displays: Backlit monochrome or color; integrated or panel–mount
  • Process connections: NPT, SAE, AN, BSPP/G, compression, VCR, or VCO fittings
  • Elastomers: Viton, FFKM, EPDM, Silicone
  • Calibration: High-accuracy; custom calibration points
  • Aggressive gas compatibility: Models with wetted materials compatible with many pure corrosive gases and most refrigerant gases, in addition to all non-corrosive gases and a variety of liquids also available.

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.
