EHP Electronic High Pressure Controller
The EHP is a high resolution digital high pressure controller with integrated microcontroller for controlling air or inert gas for a variety of applications and is recommended for use in controlling the pilot reference pressure for Equilibar dome-loaded back pressure regulators. It provides a regulated output pressure based on an electrical command signal input and controls in a range of calibrated pressures up to 500 psig / 35 bar(g).
The EHP comes standard with 0 -10 VDC signal command and can be configured for 4-20 mA differential or 3.3V serial digital command signals. It is a complete closed loop control valve consisting of two internal solenoid valves, a manifold, an electronic control circuit board, and a pressure transducer all contained in a protective IP65 rated housing.
All models are designed for use with air or inert gases in non-hazardous/non-explosive environments. For information about ATEX rated controllers, please contact us.
If you are looking for a high resolution digital pressure controller for a lower pressure range, below 150 psig / 10 bar(g), please visit the EPC product page.

EHP Electronic High Pressure Controller
The EHP is a complete closed loop controller consisting of two internal solenoid valves, a manifold, an electronic control circuit and a pressure transducer all contained in a protective IP65 rated housing. One solenoid valve functions as inlet control allowing supply media into the system which increases the controlled pressure. The other solenoid valve acts as the exhaust and will decrease the controlled pressure by venting to atmosphere.
The controlled output pressure is measured by the onboard pneumatic pressure sensor and compared to the desired (target) pressure by the EHP’s internal electronics. When the circuit detects a difference between the targeted command pressure and the actual output pressure, the circuit will energize the appropriate solenoid valve to raise or lower the pressure back to the targeted value.
