DMD 331 Differential Pressure Transmitter for Liquids and Gases Stainless Steel Sensor accuracy according to IEC 60770: 0.5 % FSO Differential pressure 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). from 0 ... 20 mbar up to 0 ... 16 bar Output signals 2-wire: 4 ... 20 mA 3-wire: 0 ... 10 V Special characteristics ► permissible static pressure -onesidedup to 30 times of differential pressure range compact design mechanical robust and reliable at dynamic pressures as well as shock and vibration 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. Preferred areas of use are Plant and machine engineering Energy industry Preferred used for IS-version Ex ia = intrinsically safe for gases and dust different electrical and mechanical connections customer specific versions BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein www.bdsensors.com info@
