The pressure transmitter DMP 343 has been especially designed for the measurement of very low gauge pressure and for vacuum applications. Permissible media are non-aggressive, dry gases and non-aggressive, low viscos oils. 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. Features: - nominal pressure: 0 ... 10 mbar up to 0 ... 1000 mbar - accuracy: 0.35 % - small thermal effect - excellent long term stability - excellent linearity Optional Features: - IS-Version Ex ia = intrinsically safe for gases and dusts - different electrical and mechanical connections - customer specific versions
