Monitoring the humidity and temperature of hydrogen cooled generators to achieve the best yield
Dry hydrogen is used to cool electric generators because of its high thermal conductivity and low viscosity. An increase in the level of moisture in the hydrogen may lead to a decrease in cooling efficiency, a reduction in insulation capability and corrosion of generator parts with the worst outcome being a total breakdown of the generator.
Vaisala’s intrinsically safe HMT360 humidity and temperature transmitter series is ideal for monitoring dryer performance. The sensor can be installed directly into a pressurized pipeline and provides measurements that show if dry hydrogen is being fed into the generator.
The intrinsically safe HMT370EX is the ideal solution for use in hazardous areas up to zone 0 and 20.
Vaisala DRYCAP® Dew Point and Temperature Probe DMP7 is made for tight spaces and low-humidity applications.
Vaisala DRYCAP® Dew Point and Temperature Probe DMP8 is designed for industrial low-humidity applications with pressure up to 40 bars.
HMT330TMK monitors the air intake of gas and liquid fueled power turbines and is used together with HMT337 Temperature and Humidity Transmitter.
