Pressure Controllers & Transducers


P–Series: Absolute and Gauge Pressure Transducers

Alicat P-Series absolute and gauge pressure transducers measure the absolute pressure (referenced to vacuum) or gauge pressure (referenced to local barometric pressure) of gases or at any point in your process. The in-line design allows you to quantify the pressure of a flowing process without introducing a dead-ended obstruction to your system.

  • Fast & accurate. Measure gas pressure in real-time with NIST-traceable accuracy to ±0.125% of full scale and a response time under 10 ms.
  • Versatile measurement. As soon as you turn on the pressure gauge, it is ready to display live pressure readings in your choice of engineering units for all non-corrosive gases.
  • Easy integration. Custom process ports and electrical connectors in addition to your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications options enables easy integration into your industrial process.

Absolute/gauge P-Series performance
  • Available ranges:
    • Absolute: max 0–3000 PSIA; min 0–15 PSIA
    • Gauge: max 0–3000 PSIG; min 0–2 inH₂O*
  • 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 measurement response time: <10 ms
  • Warm-up time: <1 s

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

Absolute/gauge P-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 ranges >500 PSI)
Available device ranges for absolute/gauge P-Series

Alicat offers gauge pressure transducers with custom pressure ranges from 2 inH₂O full scale to 3000 PSIG full scale, and absolute pressure transducers with custom pressure ranges from 15 PSIA full scale to 3000 PSIA full scale. Each has a pressure measurement range of 0.01% to 100% of full scale. Custom devices are ranged to best meet your specific application needs for full scale pressure and operating range.

It is important to note that some device specifications vary depending on the full scale pressure.
