General info – Electronic Pressure Regulators
We offer a wide range of electronic pressure regulators. Generally, each electronic pressure regulator consists of a pressure sensor, a PID-controller and electronics that control a valve.
Please find below a further description of this technology as well as information about the various electronic pressure regulators we offer you.
You can place the valve upstream or downstream of the sensor. Therefore it results in an electronic forward pressure reducing regulator or a back pressure regulator. Some models contain 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. In addition, one of the advantages of these controllers is that they do not consume any inert gas while maintaining a pressure.
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.
