Pressure Transmitter DMK 351

The pressure transmitter DMK 351P has been designed for measuring small system pressure in the food industry and chemical industry. The DMK 351P is based on an own-developed capacitive ceramic sensor element. It features high overpressure resistance and high resistance against most of aggressive media. A variety of different process and electrical connections and an intrinsically safe version complete the range of possibilities. Features: — nominal pressure: 0 ... 40 mbar up to 0 ... 20 bar — accuracy: 0,35 % (opt. 0,25 %) FSO — hygienic version — high overpressure capability — several process connections (G1" cone, Clamp, dairy pipe, etc.) (G 1/2, dairy pipe, clamp, etc.) Optional Features: — IS-Version Ex ia = intrinsically for gases and dusts — diaphragm AI2O3 99.9 % — customer specific versions e.g. special pressure ranges

The pressure transmitter DMK 387 has been specially designed for applications in plant and machine engineering as well as laboratory techniques and is suitable for measuring small system pressure and filling heights. By using our own-developed capacitive sensor, available in AI2O3 99.9%, the DMK 387 offers a high overpressure resistance and a high temperature and media resistance. The pressure transmitter is available in an intrinsically safe version for usage in explosive environments. Product characteristics: — Nominal pressure from 0 ... 100 mbar up to 0 ... 60 bar — Output signal: 2-wire: 4 ... 20 mA / 3-wire and others on request — diaphragm ceramics 99.9 % Al2O3 — accuracy: 0.35 % (opt. 0.25 %) FSO Optional features — IS-version Ex ia = intrinsically safe for gases and dust — different kinds of inch threads — pressure port in PVDF or PP-HT for aggressive media

The pressure transmitter DMK 458 has been developed for marine and offshore applications. In addition to thread connections, different flush versions are available, which are especially suitable for pasty, viscous, and polluted media. Due to the capacitive ceramic sensor developed by BD\SENSORS, which is optionally available in Al2O3 99.9 %, the DMK 458 shows an outstanding accuracy as well as a high overload and temperature resistance. Features: — nominal pressure: 0 ... 40 mbar up to 0 ... 20 bar — accuracy: 0.25 % (opt. 0.1 %) FSO — shipping approvals: American Bureau of Shipping (ABS), Bureau Veritas (BV), China Classification Society (CCS), Det Norske Veritas (DNV), Germanischer Lloyd (GL), Lloyd's Register (LR) — high overpressure resistance — excellent accuracy — accuracy: 0.25 % (opt. 0.1 %) FSO Optional Features: — IS-Version Ex ia = intrinsically safe for gases and dusts — diaphragm AI2O3 99.9 %

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)
