DMD 331 - Industrial differential transmitter for liquids and gases


The DMD 331 is a differential pressure transmitter for industrial use, based on a piezoresistive stainless steel sensor, which can be applied on both sides with fluids and gases compatible with stainless steel 1.4571 (316Ti) or 1.4435 (316L). The compact design allows the integration of the DMD 331 also in plant constructions / machines with small space available.

When pressure is applied the DMD 331 determines the pressure difference between positive and negative sides and transforms this into a proportional electrical signal.

Available output signals are 4-20 mA / 2-wire and 0-10 V / 3-wire.
