Pressure Transmitter DMP 321

The precision pressure transmitter DMP 331i and DMP 333i demonstrate the further development of our industrial pressure transmitters. The signal processing of sensor signal is done by digital electronics with 16-bit analog digital converter. Consequently it is possible to conduct an active compensation and the transmitters with excellent maesurements and exeptionally attractive price to offer on the market. Features: — nominal pressure: 0 ... 400 mbar up to 0 ... 600 bar — accuracy: 0.1 % FSO — thermal error in compensated range -20 … 80 °C: 0.2 % FSO TC 0.02 % FSO / 10 K — communication interface for adjusting of offset, span and damping — turn-down 1:10 Optional Features: — IS-Version Ex ia = intrinsically safe for gases and dusts — adjustment of nominal pressure gauges (factory-provided)

The pressure transmitter DMP 331 can be used in all industrial areas when the medium is compatible with stainless steel 1.4404 (316 L) or 1.4435 (316 L). Additional are different elastomer seals as well as a helium tested welded version available. The modulare concept of the device allows to combine different stainless steel sensors and electronic modules with a variety of electrical and mechanical versions.Thus a diversity of variations is created, meeting almost all requirements in industrial applications. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 60 bar — accuracy: 0.35 % (opt. 0.25 % / 0,1%) FSO — excellent thermal behavior — excellent accuracy — flush pressure port G 1/2" from 100 mbar Optional Features: — IS-version Ex ia = intrinsically safe for gases and dusts — SIL 2 according to IEC 61508 / IEC 61511 — pressure sensor welded — customer specific versions

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

DMP 320 stands for speed and precision. With a response time of ≤ 0.5 msec and a sampling rate of 10 kHz, the pressure transmitter was designed for applications, in which an extremely fast and exact pressure measuring is required. Pressure curves, peaks and hits can be monitored and evaluated exactly. The signal processing of the sensor signal is done by newly developed digital electronics, which detect the signal with a sampling rate of 10 kHz. Sensor-specific deviations such as non-linearity, hysteresis and temperature errors are compensated actively. Features: — nominal pressure: 0 ... 100 mbar up to 0 ... 600 bar — accuracy: 0.1 % FSO — internal sample rate 10 kHz — excellent thermal behavior — excellent long term stability — extremely short response times ≤ 0.5 ms Optional Features: — customer specific versions
