The Deltabar FMD77 differential pressure transmitter with metal sensor uses a one-sided diaphragm seal or diaphragm seals on both sides with a capillary on the low pressure side. Typically used in the process industry for continuous level measurement in liquids. The integrated HistoROM data module makes the management of process and device parameters easy. Designed according to IEC 61508 for use in SIL3 safety applications.
For level, volume or mass measurement in liquids.
