anode gas sensor

« all products NEO987A

Hydrogen sensor system for automotive applications for monitoring up to 100 vol.-% H2 in oxygen-free /inerter environment with temperature-, pressure- and humidity compensated signal evaluation for automotive applications.

The hydrogen measuring system NEO987A can measure hydrogen in inert gas up to a concentration of 100 % by volume very quickly and precisely, e.g. in the anode gas of a fuel cell. The measured values are transmitted temperature-, pressure- and humidity compensated via CAN bus .

Most important properties:

  • H2 sensitivity: 0 - 100 vol.-% H2 in N2
  • Tolerance: < ± 1 vol.-% H
  • Temperature measuring range: -40 to 120 °C
  • Pressure range: 100 - 500 kPa, i.e. 1 - 5 bar absolute
  • Humidity: 0 to 100 % r.h. (non-condensing)
  • Response time: t90 < 3 s
  • Recovery time: t10 < 3 s
  • Signal: CAN 2.0
  • Replacement for AMS HPS-100 and NEO985A
  • Can be used in the anode loop of a fuel cell
