The EL-PRESS series digital electronic pressure transducers and controllers for gasses and liquids have a well-proven compact thru-flow design. The instruments include a diaphragm type piezo-resistive pressure sensor for pressure measurement/control from: lowest ranges 2 ... 100 mbar absolute / differential or 0,7 ... 35 mbar gauge up to highest ranges 8 ... 400 bar absolute / gauge or 0,3 ... 15 bar dif.
