The EL-PRESS series 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 pressure measurement/control from:

• lowest ranges 2 … 100 mbar absolute, gauge or differential 
  
  up to highest ranges 8 … 400 bar absolute / gauge or 0,3 … 15 bar dif.

The control valve design distinguishes itself from competitive designs in its truly modular construction and it can be field replaced or changed by the user without any adjustment. The standard valve is normally closed and is available up to Kv-values of 6.0. Normally opened valves can also be supplied.
