Endress Hauser Transmitter FMD77 Intelligent Differential Pressure
Transmitter
Product Overview:
The Deltabar FMD77 differential pressure transmitter uses a metal
sensor, with either a single flange diaphragm seal or a double
flange seal, and a capillary tube on the low-pressure side. It is
mainly used for continuous level measurement in process industries.
It features a built-in HistoROM data module for easy management of
process and equipment parameters. It complies with IEC 61508
standards and meets SIL3 functional safety requirements.
