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, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process.

Device specs and customization options

Quick Specs
Absolute/gauge PC-Series performance (most products)
  • Available ranges:
    • Absolute: max 0–3000 PSIA; min 0–15 PSIA
    • Gauge: max 0–3000 PSIG; min 0–2 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 50 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).

Valve sizing and PID tuning | Valve options

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 of 20 slpm and below
  • 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 50 slpm and above

Accessories | Sold separately

  • Process port fittings and filters
  • Power supplies
  • Communications cables and conversion cables
  • BB3 and BB9 multi-drop breakout boxes
