The E+H Deltabar PMD75 Differential Pressure Transmitter features a piezoresistive sensor and a welded metallic membrane. The membrane is used in all industries for continuous measurement in liquids, vapors and gases. The PMD75 has three key operation that enables simple and reliable commissioning and operation. The integrated HistoROM data module allows easy management of process and device parameters. Designed according to IEC 61508 for use in SIL2/3 safety applications.

Applications for the PMD75 include:

  • Flow measurement (volume flow or mass flow) in conjunction with differential pressure sensors in gases, vapors and liquids
  • Level, volume or mass measurements in liquids
  • High process temperatures up to 400 °C (752 °F) possible with diaphragm seal mount
  • Differential pressure monitoring, e.g. of filters and pumps
