Description Vendor

The AHP1000H Hydrogen High Pressure Transmitter is a high-performance pressure measurement device designed for use in hydrogen-based environments. It utilizes Silicon-on-Sapphire (SOS) sensor technology, which offers outstanding stability and accuracy over a wide temperature range. The transmitter is constructed from a special titanium alloy, ensuring compatibility with hydrogen and resistance to embrittlement. It is capable of measuring pressures up to 5,000 bar and is suitable for applications such as hydrogen storage, pipeline testing, and high-pressure industrial use. The device is ATEX/IECEx certified for use in hazardous areas and includes options for DNV-GL certification. The transmitter features a compact design with dimensions of 113 mm in height and a diameter of 33 mm, and it supports various electrical connections including 4-20 mA outputs. The product is known for its high accuracy, with an error margin of ≤ ±0.25% of span BFSL for ranges above 3,000 bar, and it is designed to operate in extreme conditions with an ambient temperature range of -40°C to +85°C.

Use Cases

  • Hydrogen storage
  • Pipeline testing
  • High pressure Industrialndustrial

Capabilities

  • High pressure measurement capability up to 5,000 bar
  • Excellent corrosion resistance and hydrogen embrittlement resistance due to titanium alloy construction
  • Certified for hazardous areas with ATEX/IECEx approvals
  • Seamless titanium pressure sensor structure improves durability in extreme pressure environments
  • Intrinsically safe design suitable for zone 0
