Pressure controllers feature compact design

With a well-proven compact through-flow design, EL-Press controllers are available for absolute, gauge or differential pressure control.

With a well-proven compact through-flow design, EL-Press controllers are available for absolute, gauge or differential pressure control.

Differential pressure can be controlled up to 15bar, and the maximum pressure controller available is 700bar.

Numerous styles of valve are available, either integral, or close coupled, direct acting, pilot operated or bellows.

The EL-Press closed loop control adjusts the valve position to maintain the pressure monitored by the internal piezoresistive sensor, in response to the externally signalled setpoint.

The actual regulated pressure is relayed as an analogue and/or digital output signal.

With high accuracy and fast response time, examples of EL-Press applications are: liquid chromatography, biotechnology fermenters, liquid level control in reaction vessels, CVD process and sputtering pressure control, and protective gas atmospheres.

Pressure control can be achieved for either upstream or downstream process conditions.

Bronkhorst has a wide capability associated with this technology, for example with all-metal sealed units, and many styles of electronic interface or display units to suit all control techniques.
