The industrial pressure transmitter DMP 334 has
been especially designed for use in hydraulic systems up to 2200 bar. The base element ofDMP 334 is a thinfilm sensor, which is welded withthe pressure port and meets high demands of andreliability.
All of characteristics and the excellent measurement data of DMP 334 as well as distinguishedoffset stability offer a pressure transmitter witheasy handling, reliability and robustness for hydraulic user. The DMP 334 is deliverable withstandard HP connections.
Preferred areas of use arePlant and Machine Engineering
Commercial Vehicles and MobileHydraulics
