Description Vendor

The AGS4200H is a Hydrogen Pressure Transmitter designed for use in hydrogen-based environments. It features Silicon-on-Sapphire (SOS) sensor technology, which ensures high accuracy, durability, and long-term stability. The transmitter can withstand pressures up to 1,500 bar and is built with a specialist titanium alloy to enhance performance and corrosion resistance in hydrogen environments. It is compatible with hydrogen storage, production, and marine propulsion applications. The AGS4200H offers ATEX/IECEx and DNV-GL certifications, making it suitable for hazardous areas and marine environments. The transmitter is also equipped with a titanium alloy construction, ensuring excellent resistance to overpressure and pressure transients. The device is certified for hydrogen compatibility and includes a certificate of conformity confirming its suitability for use in hydrogen environments.

Use Cases

  • Hydrogen storage
  • Hydrogen production
  • Marine propulsion

Capabilities

  • Constructed from specialist titanium alloy providing excellent corrosion resistance and hydrogen compatibility
  • Withstands overpressure up to 2x rated pressure range
  • Long-term stability and minimal hysteresis
  • Certified for hazardous areas: ATEX/IECEx and marine (DNV-GL)
  • Excellent insulation and pressure transient resistance due to sapphire sensor technology
