  • The DMP 336 is an industrial pressure transmitter specifically designed for technical gases and hydrogen applications.
  • It features a welded, dry stainless steel sensor with high accuracy of 0.5% FSO, ensuring precise measurements. The media-wetted parts are made of special stainless steel (316L) to prevent hydrogen embrittlement, making it suitable for hydrogen and other technical gases.
  • The transmitter is insensitive to pressure peaks and offers high overpressure capability, enhancing its reliability in demanding environments. An optional IS-version is available for explosion-protected applications in zones 0 and 20, meeting safety standards like IEC 61508 and IEC 61511.
  • It is also oil and grease-free, complying with ISO 15001, which is crucial for oxygen applications. The DMP 336 is suitable for use in technical gases, hydrogen, fuel cells, and medical technology, and meets various compliance standards such as CE, ATEX, and ROHS. It provides a 2-wire output signal of 4...20 mA and is available with different pressure ranges from 0...16 bar up to 0...1000 bar.
  • The transmitter is built with a stainless steel housing (316L) and is designed for durability, with features like vibration resistance, electromagnetic compatibility, and a wide operating temperature range of -40...125°C.

Use Cases

  • Technical gases
  • Hydrogen
  • Fuel Cells

Capabilities

  • Measures pressure of hydrogen and other technical gases over nominal ranges from 0 … 16 bar up to 0 … 1000 bar
  • High overpressure capability, up to 1500 bar for 1000 bar nominal range, with specified burst pressures up to 3000 bar.
  • Oil- and grease-free version according to ISO 15001 for oxygen applications, reducing contamination risk.
  • Accuracy ≤ ±0.5 % FSO (non-linearity, hysteresis, repeatability) per IEC 61298-2.
BD SENSORS GmbH BD|SENSORS GmbH is a German manufacturer of electronic pressure and level measurement technology, founded in 1995 and headquartered in Thierstein, Bavaria, with a dedicated product line of pressure transmitters engineered for hydrogen and technical gas applications. The company's DMP 336 and DMP 333P pressure transmitters use special stainless steel (316L, welded, gold-plated process connections) wetted parts to resist hydrogen embrittlement, while its DCT 541 offers a digital interface variant for hydrogen and technical gas measurement. BD|SENSORS operates as a globally active group with sister company BD SENSORS s.r.o. serving Eastern Europe, supplying pressure and level instrumentation broadly used across hydrogen production, storage, and mobility applications including electrolyzers, fuel cells, and hydrogen refueling infrastructure. The company has been developing electronic pressure measurement technology for nearly 30 years.
