E+E EE04 Specifications
EE04
Miniature Humidity and
Temperature Transmitter
The high quality, compact EE04 humidity and temperature
transmitters are optimised for OEM applications. Highest
performance with respect to accuracy and long term stability
is combined with low costs for large quantities. The SMD
humidity sensor HC103 series, state of the art electronics
and dedicated housing are offering an excellent price /
performance ratio.
An optional filter assures optimal protection against dirt. For use
in high pollution or corrosive environment the sensors and
electronics can be protected with a special E+E coating.
There is an EE04 version model available with extra air slots on
the side allowing for very fast response times.
EE04-FTB
The linear output voltage for relative humidity can easily be
processed further. The temperature output signal is provided by a voltage divider with passive NTC sensor.
Fast and easy installation is possible by using the provided mounting flange.
