The AK100 Series is an ATEX-compliant gas analyzer system designed for monitoring hydrogen purity and purge gas in hydrogen-cooled alternators. It consists of a display monitor, gas analysis panels, and power supply units, with intrinsically safe certification [Ex ia Ga] IIC for use in hazardous areas. The system operates with thermal conductivity measurement using a katharometer principle and includes zener barriers for safety. The display monitor measures 290 x 362 x 272 mm and weighs 12 kg. Gas analysis panels are available in low-pressure (6540-203) and high-pressure (6548-000) variants, rated for sample pressures up to 0.35 bar (gauge) and 10 bar (gauge) respectively. The system supports CENELEC, BASEEFA, and EN61010-1:2010 approvals, with ambient operating temperatures from 0 to 40 °C. It is configured in variants AK101, AK102, AK103, and AK104 to suit differing redundancy and measurement requirements.
The H2 purity and purge gas monitor AK100 provides a complete system for monitoring hydrogen purity during normal operation and purge gas monitoring during commissioning and decommissioning of the generator.
