DMP 33 1Industrial
Pressure Transmitterfor Low Pressure
Stainless Steel Sensor
accuracy according to IEC 60770:
standard: 0.35 % FSO
option: 0.25 / 0.1 % FSO

Nominal pressure

The pressure transmitter DMP 331 can be usedin all industrial areas when the medium is compatible with stainless steel 1.4404 (316 L) or
1.4435 (316 L). Additional are diﬀerent
elastomer seals as well as a helium tested
welded version available.

from 0 ... 100 mbar up to 0 ... 60 bar
Output signals
2-wire: 4 ... 20 mA

3-wire: 0 … 20 mA / 0 … 10 VThe modulare concept of the device allows tocombine diﬀerent stainless steel sensors andelectronic modules with a variety of electricaland mechanical versions.Thus a diversity ofvariations is created, meeting almost all requirements in industrialapplications.
