Pressure Controllers & Transducers

Overview

Fast pressure controllers keep your process stable and repeatable. Alicat offers pressure controllers for use in flowing, dead-ended, or vacuum applications. Dual-valve models for closed volumes eliminate the need to continuously bleed expensive process gases. Instruments are available with absolute, gauge, or differential pressure sensors for pressure control as high as 3000 PSIA/PSIG (or 150 PSID) and as low as 2 inH₂O.

Pressure Controllers for Flowing Processes

Open in new window

Use pressure controllers when gas is flowing through a process. They control absolute, gauge, or differential pressures, and can measure in-line pressures or be plumbed to measure process pressures at any point.

Use Alicat pressure controllers to rapidly measure and control absolute, gauge, or differential pressure.  Pressure controllers are accurate to ±0.25% of full scale, with a measurement range from 0.01-100% of full scale.

Absolute pressure can be measured up to 3,000 PSIA and as low as 15 PSIA before turndown. Gauge pressure instruments measure as low as 2 inH₂O and can measure negative gauge pressure to -15 PSIG.

Common configurations including anti-corrosive are available, as are electronic pressure controllers and controllers for vacuum processes.

Pressure Controllers for Closed Volumes

Open in new window

Use pressure controllers to control pressure in a closed volume. They control absolute, gauge, or differential pressures, and can measure in-line pressures or be plumbed to measure process pressures at any point.
