DMP 304
IndustrialPressure Transmitterfor Ultra High Pressure
accuracy according to IEC 60770:
standard: 0.5 % FSO
option: 0.25 % FSO

Nominal pressure

Theultra-high-pressuretransmittertype
DMP 304 has been especially designed for
applications with highest demand on precisionand reliability. DMP 304 series is based on acompensated strain gauge, bonded onto ahardened stainless steel diaphragm.

from 0 ... 2 000 bar up to 0 ... 6 000 bar
Output signals
2-wire: 4 ... 20 mA
3-wire: 0 … 10 V

Due to the rugged stainless steel housing usage
under extreme conditions and in IS-required
areas is no problem.
