Description Vendor

The AHI2000 is a high precision pressure transmitter that utilizes Silicon-on-Sapphire (SOS) sensor technology for outstanding performance. It offers an operating range up to 1500 bar with an accuracy rate of less than ±0.1% of span, which is a level of precision previously unobtainable or prohibitively expensive. The transmitter features titanium wetted parts for excellent chemical compatibility and high thermal stability over a wide operating temperature range. It is ATEX/IECEx approved for use in hazardous environments, including mining applications (M1). The AHI2000 is suitable for applications such as Laboratory and Test, Aerospace, and Oil and Gas monitoring (downhole).

Use Cases

  • Laboratory and Test
  • Aerospace
  • Oil and Gas monitoring (downhole)

Capabilities

  • High precision pressure measurement up to 1500 bar
  • Excellent chemical compatibility and corrosion resistance via titanium wetted parts
  • High thermal stability and long-term performance
  • Intrinsically safe design with ATEX/IECEx certification for hazardous and mining zones
  • Silicon-on-Sapphire sensor enables low hysteresis and high accuracy
ALTHEN BV Sensors & Controls Althen (Althen Sensors & Controls) is a European sensor technology distributor and manufacturer offering a dedicated range of hydrogen-compatible pressure sensors for the growing hydrogen economy. Its GENSPEC and AHP series transducers use Silicon-on-Sapphire and titanium alloy construction, tested to ISO 11114-2:2017 and EU hydrogen regulations, with pressure ranges up to 5,000 bar for applications including hydrogen refueling stations, fuel cell systems, storage tanks, and test benches. Althen also supplies ATEX/IECEx-certified sensor variants for hazardous hydrogen environments. The company operates across Europe, including a presence in Belgium, supporting hydrogen, transport, energy, and industrial manufacturing customers with precision measurement solutions.
