data sheet DMP 343 - 1

DMP 343 Industrial Pressure Transmitter Without Media Isolation accuracy according to IEC 60770: 0.35 % FSO from 0 ... 10 mbar up to 0 ... 1000 mbar Product characteristics ► excellent linearity small thermal effect excellent long term stability The DMP 343 features excellent thermal behaviour and outstanding long term stability. A variety of standard output signals as well as mechanical and electrical connections make the DMP 343 covering a wide field of applications. IS-version: Ex ia = intrinsically safe for gases and dusts different electrical and mechanical connections The pressure transmitter DMP 343 has been especially designed for the measurement of very low gauge pressure and for vacuum applications. Permissible media are nonaggressive, dry gases and non-aggressive, low viscos oils. customer specific versions Preferred areas of use are Plant and machine engineering Heating and air conditioning BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein www.bdsensors.de info@
