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 10 torr.

Alicat 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.

Check out the model pages to learn more about our pressure controllers and the many custom build and performance options that are available.

Alicat Pressure Controllers for Closed Volumes

Dual valve pressure controllers from Alicat eliminate the need for a bleed valve for pressure control in closed or dead-ended volumes. They 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.

Alicat Differential Pressure Controllers and Transducers

Alicat differential pressure instruments measure the difference in pressure between any two points in your process. If you leave the downstream port open to atmosphere, the differential pressure readings become equivalent to gauge pressure readings, allowing differential pressure instruments to double as gauge pressure instruments.
