Electronic Pressure Controllers, Customised

Alicat Scientific has added two new families of Electronic Pressure Controllers specifically for high volume original equipment manufacturers. The EPC family with single proportional valves, and EPCD family with dual valves, provide customised pressure control in embedded systems. The small footprint instruments respond quickly to upstream fluctuations to provide fast, accurate control of pressure in an economical, easy-to-integrate package. Alicat offers a choice of valves, valve orifices and process connections to fit customer specifications. EPC instruments are ideal for use in OEM gas chromatographs, fluidics dispensing for flow cytometry, and anywhere responsive pressure control is needed. EPC and EPCD instruments have a 100 ms control response to still upstream pressure fluctuations in real time. NIST-traceable accuracy is 0.25% full-scale. The EPC family’s single proportional valve provides stable control of pressure in flowing applications, such as maintaining flow of carrier gas through the sample injection point in gas chromatographs. The EPCD features a second exhaust valve to provide efficient control of pressure in closed volumes, such as controlling the head space above a fluid for dispensing.
