Pressure / vacuum gauge

Digital pressure transducer

Fast and accurate electronic pressure monitoring

Alicat Scientific P-Series digital pressure transducers accurately and rapidly measure the absolute, gauge or differential pressure of process gases and liquids. Differential pressure gauges measure the pressure differential between two points in a process using separate dead-ended pressure sense ports.

PC/PCR Single-Valve Pressure Controllers for Flowing Volumes

Alicat PC-series single-valve pressure controller for flowing volumes

Control pressures in flowing volumes with fast control response and rock-solid stability. May be customized with a remote sense port (PC3) or anti-corrosive construction (PCS).

Go to Single-Valve Pressure Controller page.


PCD/PCRD Dual-Valve Pressure Controllers for Closed Volumes

Alicat PCD-series dual-valve pressure controller for closed volumes

Control pressures in closed or dead-ended volumes without wasting costly gases through a continuous bleed valve. The PCD Series incorporates a second exhaust valve that actuates only when the pressure needs to be reduced. May be customized with a remote sense port (PCD3) or anti-corrosive construction (PCDS).

Accuracy

  • Standard accuracy (NIST-traceable): +/- 0.25% of the full-scale range
  • Optional high-accuracy calibration: +/- 0.125% of the full-scale range
  • Linear range: 0.5-100% of full scale, 200:1 turndown

Speed of Response

  • Typical response time constant: 5 ms
  • *Actual pressure stabilization time also depends upon application setup.

Ranges

  • Gauge ranges (referenced to atmosphere): any full-scale range from 0-2 inH2O(G) to 0-2000 psig. Negative ranges (-15 to 0 psig) also available. *PS ranges start at 0-1 psig.
  • Absolute ranges (referenced to vacuum): any full-scale range from 0-15 psia to 0-2000 psia. *PS ranges start at 0-30 psia.
  • Differential ranges (referenced to each other): any full-scale range from 0-2 inH2O(D) to 0-150 psid. *PS ranges available from 0-1 psid to 0-100 psid. Negative readings indicate an inverse pressure differential.

Ask Alicat: What Is Pressure Drop?

Pressure drop is the amount of line pressure that is permanently lost as gas passes through an instrument in a gas line. Alicat Scientific demonstrates the importance of pressure drop for gas flow processes.

The Fastest Flow Controller Company in the World

How can Alicat claim to be the fastest flow controller company in the world? This video introduces you to some of the many ways that Alicat mass flow and pressure instruments can make you more efficient, saving you time and money.

Ask Alicat: How do you control pressure in a closed system?

Alicat Scientific demonstrates the best way to control pressure in a dead-ended or closed system. Using a dual-valve pressure controller can save you money over a conventional single-valve pressure controller plus bleed valve setup.

Ask Alicat: How tough is an Alicat flow meter? (Drop Test)

We drop an Alicat portable mass flow meter onto unforgiving concrete from increasing heights to test the toughness of this product. After each drop, we compare its measurement to the pre-test baseline.
