DMD 331

BD Sensors DMD 331 Differential Pressure Transmitter for Liquids and Gases Featuring Stainless Steel Sensor with Accuracy According to IEC 60770 of 0.5 % FSO, Differential Pressure from 0 … 20 mbar up to 0 … 16 bar

SKU: DMD 331 Category:

The DMD 331 is a differential pressure transmitter for industrial applications and is based on a piezoresistive stainless steel sensor, which can be pressurized on both sides with fluids or gases compatible with SST 1.4404 (316L) and 1.4435 (316L). The compact design allows an integration of the DMD 331 in machines and applications with limited space. The DMD 331 calculates the difference between the pressure on the positive and the negative side and converts it into a proportional electrical signal. Areas of use include plant and machine engineering, energy, & water.
