Note
Alternative parameters are calculated internally from the measured variables,
which are retrievable via the active output OUT3:
absolute humidity, mixing ratio, dew point and wet bulb temperature
(can be changed via DIP switch)
ACCESSORIES
SF-M
Metal sinter filter, Ø 16 mm, L = 32 mm, exchangeable
stainless steel V4A (1.4404)
WS-03
Weather and sun protection hood, 200 x 180 x 150 mm,
stainless steel V2A (1.4301)
A constant overtemperature of the humidity sensor makes its dewing considerably
more difficult or prevents its formation within the limits of the system.
A faster reaction speed is achieved in the case of humidity fluctuations, even in the
range above 95 % RH. The sensor (combined humidity and temperature measuring
element) is heated approx. 3 K above the ambient temperature. The actual relative
humidity is determined from the measured relative humidity at overtemperature,
the chip temperature of the sensor and the ambient temperature (via a second,
separate temperature measuring element).
