These servo EPRs allow for output pressures significantly greater than previous pressure transducers. Boxes 1-4 serve the same purpose as above. These EPRs typically require a DC power supply and a set-point signal. The Proportional Ratio Assembly (PRA) provides a solution for applications requiring high pressure electronic control of inert gas pressure greater than 1000 psig / 68.9 bar(g) up to 5000 psig / 414 bar(g) using electro-pneumatic controls.
Designing a pressure control system can be a long-term project with frequent specification changes. In the past decade, the fastest growing type of electronic pressure regulator has been the servo valve design, which uses two high speed servo or solenoid valves to increase or decrease gas pressure as needed to maintain pressure.

There are several critical parameters for the successful application of this technology. You are here: Home High Pressure Electronic Controller. Digital electronic pressure control with microprocessor and keypad control. The EPR-3000 can be quickly commanded using the convenient keypad interface. Often, a mechanically adjusted regulator is used to regulate a high pressure gas source (often a nitrogen bottle) down to the desired pilot pressure. Fletcher, North Carolina

The pressure in the reactor is commanded by the computer through an electronic pressure regulator, which produces an air or nitrogen pressure signal to the dome-loaded BPR.
The BPR allows only enough gas to escape from the reactor to precisely maintain the desired pressure setting. You are here: Home Products Electronic Pressure Regulators EPR 1000 High Precision Electronic Pressure Regulator, EPR 1000 High Precision Electronic Pressure Regulator. For some models, gas volumes less than approximately 1 liter can cause issues such as buzzing or frequent and unnecessary valve action.
For example, with a 0 10 V = 0 1 psig / 68 millibar(g) unit, giving the unit a command of 5V tells the unit to go to 0.5 psig / 34 millibar(g) and giving the unit a command of 10V tells the unit to go to 1 psig / 68 millibar(g). Equilibar QPV1 electronic pressure regulator.
Because both the EPR-3000 and the back pressure regulator have no significant hysteresis or dead-band, it is possible to precisely control reaction conditions even with highly varying process flow rates. *Meant for use with air or inert gases only.

The dome-loaded design allows initial setup with a manually controlled system, then subsequent setup with electronic control without having to purchase a new back pressure regulator. Fletcher, North Carolina The schematic above shows how a dome-loaded back pressure regulator can be used to control the flow rate to a dispensing application. While this example does use a PID flow controller, the reaction time of this system is infinitely faster than that of a PID controlled control valve. This allows the system parameters to be monitored and provides a signal for data acquisition needs. The orifices in these valves come in several different sizes and should be matched according to the required flow rate. An Equilibar BPR is set up in a recirculating loop with control configuration emulating cardiovascular pressure using a pulse wave input into an electronic pressure regulator, or electropneumatic (E/P) controller.
