Features

  • Supports both absolute and gauge pressure.
  • Uses a metal diaphragm (membrane) for accurate measurement of liquids and gases.
  • Measuring cell range: 1 bar up to 400 bar (about 14.5 psi … 5800 psi).
  • Very high overpressure capability: max overpressure up to 2800 bar (per some spec sheets)
  • The device is developed in line with IEC 61508 (functional safety).
  • Comes in Endress+Hauser’s “FLEX” product family, meaning a balance between technical performance and simplicity.
