Description Vendor
  • The Industrial Pressure Transmitter DCT 541 is a high-precision device designed for use with technical gases such as hydrogen and oxygen.
  • It features a welded, stainless steel sensor and offers an accuracy of 0.5% FSO according to IEC 61298-2.
  • The transmitter supports a wide range of nominal pressures from 0 ... 16 bar up to 0 ... 1000 bar and provides an RS485 output with Modbus RTU protocol, enabling reliable communication in industrial environments.
  • It is particularly suited for applications requiring high overpressure capability and resistance to pressure peaks.
  • The device is constructed with special stainless steel to minimize hydrogen embrittlement and includes a cleaning process to ensure safety for oxygen applications.
  • The DCT 541 is suitable for use in technical gases, hydrogen, fuel cells, and medical technology, and is compliant with various international standards including Modbus CE, RoHS, REACH, and UL.

Use Cases

  • Technical gases
  • Hydrogen
  • Fuel cell
  • Medical technology

Capabilities

  • Communication via RS485 with Modbus RTU protocol
  • Wide nominal pressure range from 0 … 16 bar to 0 … 1000 bar
  • High overpressure and burst pressure tolerance (up to 1500 bar / 3000 bar burst)
  • Constructed from 316L stainless steel to minimize hydrogen embrittlement
  • Cleaned and manufactured oil/grease-free per ISO 15001 for oxygen service
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.
