Bronkhorst digital electronic pressure transducers and controllers for gases and liquids have a well-proven compact thru-flow design. The instruments include a diaphragm type piezo-resistive pressure sensor for accurate and reliable measurement. Various control valves can be offered for specific field of applications. There is a standard direct acting valve for common applications, a pilot operated valve for high flow rates, and the so-called Vary-P valve that can cope with up to 400 bar ΔP. Bellows valve for applications with very low differential pressure. For specific fields of application, customers may prefer to apply a metal sealed version, a rugged IP65 version, a microfluidic instrument or the most field proven, allround EL-PRESS series.
