Pressure Controllers & Transducers


PB–Series: Portable Absolute and Gauge Pressure Transducers

Alicat PB-Series portable absolute and gauge pressure transducers are excellent instruments for convenient on-the-go process calibration, verification, and validation. Measure the absolute pressure (referenced to vacuum) or gauge pressure (referenced to local barometric pressure) of gases 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.

  • Portable & durable. These meters are made to be carried around, with a battery lifetime of up to 18 hours and the ability to withstand drops.
  • 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.
  • Fast & accurate. Measure pressure in real-time with NIST-traceable accuracy to ±0.125% of full scale and a <10 ms response time.
  • 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.

Accessories included with purchase:

  • Micro-USB to USB cable for power and serial communication.
  • USB to wall adapter converter with four interchangeable prong configurations.
  • FlowVision software (free download)

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

Absolute/gauge PB-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 PB-Series

Alicat offers portable gauge pressure transducers with custom pressure ranges from 2 inH₂O full scale to 3000 PSIG full scale, and portable 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.
