Electronic Pressure Controllers are precision electronic devices that maintain a pneumatic process pressure at a preset level using closed-loop control. These devices can be configured to control pressure, vacuum or flow and replace mechanical control systems or mass flow controllers. The required pressure or vacuum values are adjusted via an electrical set point to the EPC. The system continually measures actual process value,s compares it with the desired set point and compensates for any variations. Output signals are available for improved process monitoring. To control gas flow, EPCs are connected to an application-specific measuring orifice. By controlling the pressure in front of theorifice, the proportional flow can then be adjusted. EPCs can regulate liquid flows such as in precision dispense applications. Typical applications for these electronic pressure controllers feature carrier gas flow control, microfluidic flow control, vacuum pump control, gas-over-liquid flow control, hydro-dynamic focusing and aspirate/dispense applications.

The last issue of IEN Europe before the summer break features a Special on Hydraulics & Pneumatics . Read a technical article on the effective Monitoring of Hose Assemblies , or get to know more about the Role of Valves in Industrial Automation . This month’s Cover Story is a case story on reducing the setup times of machinery by using automated actuators. In our Interview , a representative from the company Flir talks about the possibilities of thermography in industrial applications and recent advancements. As usual, we provide you with lots of add-on information, such as videos and data sheets.
Enjoy IEN Europe June/July and have a great summer.
