Cryogenics & Advanced Materials

Stable, accurate, and compact sensors for extreme low-temperature environments

Market challenge

  • Cryogenic fluids like liquid hydrogen (LH₂), helium or nitrogen require high-precision, drift-free measurement under severe thermal, mechanical and environmental constraints.
  • Tanks often operate under high pressure, vibration and electromagnetic interference (EMI) — and require compact, ATEX-compatible components
  • Systems must deliver consistent accuracy across the entire measurement range, with no recalibration.
  • Operators demand predictive maintenance, quick probe replacement, and additional safety features like level limit detection.
  • Space, aerospace, energy and scientific industries often require highly compact and embedded electronics, compatible with pressurized tanks, confined volumes and mobile applications.

Our expertise

FOGALE Sensors provides capacitive cryogenic measurement solutions trusted by major players in hydrogen and advanced material systems:

  • Immersible capacitive probes, installed and guided inside the tanks, in direct contact with liquified gas ensuring high fidelity measurement
  • Full-range precision measurement with < ±0.5% total error — stable under pressure and temperature drift
  • High mechanical tolerance to vibration and centering shifts (e.g. flexible tanks or mobile use cases)
  • Removable sensors for quick, non-invasive maintenance — improve uptime, lower service cost
  • Optional level detection system (ie : 90%) as a separate probe for safe tank filling and redundancy
  • Available with ATEX-compatible electronics for hazardous environments
  • Multiple electronics formats: miniature, OEM-integrated, or standalone rack-based syste

Proven applications

  • Get precise, real-time mass and level measurements for LH₂ and other cryogenic fluids
  • Improve maintenance and availability with removable, connectorized sensor assemblies
  • Ensure safe operation with redundant high-level limit detection (90%)
  • Integrate reliably into vibration-prone or mobile environments
  • Comply with ATEX zone constraints 
  • Leverage a mature, robust solution already proven in mobile and industrial platforms

Key Benefits

  • KRYON : Capacitive Mass and level Probes for LH₂ and other liquified gases including :
    • Level monitoring and level detection modules as independent safety systems
    • Flexible or rigid sensor geometries tailored for OEM tanks
    • Removable sensor assemblies with connectorized modules
