About Electronic Pressure Controllers

Cv: 10E-6 … 0.35  |  Max. Temperature: -10°C … 70°C  |  Max. Pressure: 700 barg

 

There are different methods on how to supply the reference pressure to your dome-loaded back pressure regulator. When your process is automatic or when you require optimal precision and repeatability, you can automate your back pressure regulator.

We offer a wide range of electronic pressure controllers and regulators to combine with your back pressure regulator. Generally, each electronic pressure controller consists of a pressure sensor and a PID-controller that control one or two valves (Single Valve Controllers or Dual Valve Controllers).

Pressure Control Solutions is an independent reseller. We help you to choose the electronic pressure controller that is right for your process. Please find below a further description of this technology as well as information about the various electronic pressure regulators we offer you.

How to automate your back pressure regulator?

If you have an automated process, you can use our electronic pressure controllers to pilot your back pressure regulator. Most electronic pressure controllers operate with an analog signal like 0…5(10) Vdc or (0)4 to 20 mA signal. Digital bus communication like EtherCAT, ProfiNet, Profibus, Modbus, etc is available on several models.

You can place the valve upstream or downstream of the sensor, creating an electronic forward pressure reducing regulator or a back pressure regulator. Models that contain one valve usually have a constant bleed. The bleed allows the controller to keep the proportional valve in control all the time resulting in the highest possible stability. The downside of a single valve solution is the constant use of high-pressure gas.
To prevent gas consumption, we can supply solutions containing two proportional valves. You can use these instruments to control the pressure in a dead volume. The electronics will decide if the upstream valve or the downstream valve needs to open to increase or decrease the pressure in a volume. These regulators are often used to set the desired pressure in dome-loaded back pressure regulators. The bandwidth in which both valves are closed and the consumption is zero, is often in the range of 0,1% of the full-scale value of the selected pressure controller.

Pressure Control Solutions offers a wide range of electronic pressure controllers

Our product range for electronic pressure controllers is unique in the market and largely comes from (co-)development between PCS and our suppliers.

Besides single channel electronic pressure regulators, we also offer multi-channel units. Customers use these units often for high throughput catalytic systems where you can keep more reactors under pressure by Equilibar® back pressure regulators. You can use the multi-channel units to create a very stable pressure at the reference of a dome loaded valve. Have a look at this Multi-Channel Electronic Reference Controller.

The selection of the right product for your application mainly depends on the pressure that you want to maintain at the reference of the back pressure regulator. If you need low pressure and you have machine shop air available, you might be less focused on consumption of air. For higher pressures, consumption of air becomes more relevant. There are different solutions available keeping a close eye on the consumption of pressurized gas. Dual valve electronic pressure regulators are available up to 700 bar gauge.
