|Name||DLR Lyman Alpha L-5|
|Name||Non dew/frost point hygrometer|
|Measured parameter||Water Vapour, Relative Humidity|
The MOZAIC-Humidity Device (MHD) is a special airborne humidity sensing device (AD-FS2), developed by Aerodata (Braunschweig, Germany) and based on the humidity and temperature transmitter HMP230 of Vaisala (Helsinkin, Finnland). The sensing element itself is a combination of a capacitive relative humidity sensor (Humicap-H, Vaisala) and a Pt100 temperature sensor which has been installed in a Rosemount housing mounted on the outside skin of the aircraft in the vicinity of the nose cone.
|External dimension||Permanently installed|
|Operating mode||In situ|
Permanently installed; needs periodic calibration; measurements within clouds can be erroneous due to droplet evaporation within the inlet
Certified only for FA20-DLR
