NEO986I

H2 leak detection sensor system

« all products NEO986I

Hydrogen measuring system in oxygen-free/inert environment with temperature, pressure and air humidity compensated signal evaluation. Typical application is e.g. the use in the anode circuit of PEM fuel cells to determine a tertiary mixture of hydrogen, nitrogen and water vapour or to determine hydrogen concentrations under inert conditions.

Most important characteristics:

  • Measuring range H2: 0 to 100 vol.% in N2
  • Tolerance ± 2 % by volume H2
  • Temperature measuring range: -40 to 85 °C
  • Pressure range: 0.6 to 5 bar absolute
  • Air humidity: 0 to 100 % r.h. (also condensing)
  • Response time: t90 < 5 s 
  • Recovery time: t10 < 5 s
  • Signal output via 0-10V DAC or 4-20 mA
