Digital hydrogen compatible pressure transmitter – GD4200HUSB

  • The GENSPEC® GD4200HUSB series of digital, hydrogen compatible pressure transmitters, with state-of-the-art SOS sensor technology.
  • High accuracy pressure measurement from vacuum up to 5,000 bar.
  • All welded, special grade titanium sensor for reliable performance in demanding environments.
  • Pressure diaphragm and process connection is machined from one piece of specialist high strength titanium alloy with no seals or welds. This is especially important for use with very high pressures and hydrogen due to the embrittling nature of the media.
  • Tested to ISO 11114-2:2017 according to EC79/2009 and EU406/2010. Results have provided a pass rating for the compatibility of the specialist titanium alloy with hydrogen.
  • Sample rate software selection up t0 1,000 Hz.
  • Measure & record up to 16 pressure inputs at one time.
  • “Plug & Play” unit with live pressure data.
