DMK 387

Product catalog summary

Overview: The DMK 387 is a pressure transmitter designed by BD SENSORS GmbH, suitable for applications in plant and machine engineering, laboratory techniques, and environments with aggressive media. It features a ceramic sensor with high accuracy and long-term stability.

Specifications: The transmitter offers a nominal pressure range from 0 to 100 mbar up to 0 to 40 bar, with an accuracy of 0.35% FSO as standard and an optional 0.25% FSO. It provides a 2-wire output signal of 4 to 20 mA, with 3-wire options available on request.

Product Characteristics: The device includes a ceramic diaphragm made of 99.9% Al2O3, ensuring high overpressure and temperature resistance. It is available in an intrinsically safe version for explosive environments.

Optional Versions: Options include IS-version for intrinsic safety, various inch threads, and pressure ports made of PVDF or PP-HT for handling aggressive media.

Performance: The transmitter has a long-term stability of ≤ ±0.1% FSO per year, a turn-on time of 450 msec, and a measuring rate of 80 Hz. It operates within a compensated temperature range of -20 to 80°C.

Mechanical and Electrical Specifications: The device is protected against short-circuits and reverse polarity. It complies with electromagnetic compatibility standards and can withstand vibrations up to 10 g RMS. The pressure port and housing are available in stainless steel, PVDF, or PP-HT.

Explosion Protection: The DMK 387 is certified for use in explosive zones with specific temperature and pressure conditions, adhering to ATEX and IECEx standards.

Miscellaneous: The transmitter has a maximum current consumption of 22 mA, weighs approximately 180 g, and is designed for a long operational life of 100 million load cycles. It conforms to CE standards under the EMC and ATEX directives.

Ordering Information: Various configurations are available, including different mechanical connections, seals, and electrical connections. Custom options can be requested for specific applications.
