  Deltabar PMD75

  Differential pressure transmitter with metal sensor for measurement of pressure differences

  The Deltabar PMD75 differential pressure transmitter with with piezoresistive sensor and welded metallic membrane is used in all industries for continuous measurement in liquids, vapors and gases. The 3-key operation 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.
