Generator Humidity Monitor (GHM)
High moisture content (dew point) in hydrogen cooling gas is undesirable and can lead to a breakdown in the insulating system or assist in the development of stress corrosion cracking in retaining rings.
The supply of clean, dry hydrogen alone cannot assure low moisture content within the generator case because moisture vapors may be present in the seal oil system.
Knowing Your Dew Point Is Critical
E/One’s Generator Humidity Monitor is a reliable, self-contained, panel-mounted system that provides continuous measurement of the moisture content. The combination of an advanced ceramic moisture sensor coupled with superior digital measurement circuitry provides a real time, stable reading. All sensors are fully interchangeable without the need for display recalibration. The dew point is indicated locally on an LCD display and remotely via a 4-20 mA output that corresponds to -100 to +20 C or -148 to +68 F (optional).
