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

Single valve pressure controllers from Alicat are designed to rapidly control absolute, gauge, or differential pressure of flowing processes. These device are available with internal pressure sensors, or with remote sensors that can be plumbed to any point in your process. Each pressure controller is compatible with non-corrosive gases, and anti-corrosive models are available for use with corrosive gases or liquids.
