Equilibar offers a wide range of precision electronic pressure regulators (EPRs) for controlling air or inert gas for a variety of applications. These are recommended for use in controlling the pilot reference setpoint pressure for Equilibar dome-loaded back pressure regulators and vacuum regulators. All models shown here are designed for use with air or inert gases in non-hazardous/non-explosive environments. For information about ATEX rated controllers, please contact us.
For best performance when using these EPRs as a pilot setpoint regulator for an Equilibar BPR, a tubing connection between the outlet of the electronic regulator and the dome of the BPR should have a minimum volume of 2 cubic inches / 35cc.
Our application engineers will work with you to find the right solution for your automated application.
