EE33-M
E33-M is optimized for reliable measurement under
demanding weather conditions. Besides accurate
measurement of relative humidity (RH) and temperature
(T), the device calculates all additional physical quantities
like dew point temperature, absolute humidity and mixing
ratio. A dual heating system prevents condensation on
the RH sensor, on the sensing probe and on the lter
cap, which leads to extremely short response time and
fast recovery after condensing conditions. The measuring
principle with separate RH and T probes enables precise
continuous measurement even at permanent high
humidity.
The proprietary E+E coating protects the RH sensor and
its leads against corrosive and electrically conductive
pollution. The probes are compatible with modern,
ventilated radiation shields, like the LAM630.
With an optional connecting cable and the EE-PCS
software (included in scope of supply) the user can easily
perform an adjustment or a conguration of the outputs.

Monolithic Humidity Sensor
The heart of EE33-M is the monolithic HMC01 sensor, developed and
manufactured in thin-film technology by E+E Elektronik. HMC01 combines the
moisture and heating element on a single substrate. Condensation is prevented by controlled heating of the sensor. The proprietary E+E coating protects
the sensor and its leads against pollution and corrosion.
Radiation Shield
In order to minimize the impact of rain, snow, ice and solar radiation on the measurement the EE33-M must be mounted inside a radiation shield.
The radiation shield LAM630 is suitable for mounting onto a mast with 30-35mm
diameter. Forced ventilation is provided by the control unit STEG6003. Up to 4 probes
can be mounted using cable glands (Ø 18-25 mm).

Network Compatibility / Ethernet Interface
The optional RS485 interface (order code N) allows for
building a network of up to 32 transmitters.
The measurement data can be collected in a shared
database and made available for all kinds of further
processing.
