This sensor combination is used for the measurement of
the air temperature, the relative humidity and the global radiation of the
sun.
The air temperature sensor consists of a
temperature-dependent silicon regulated current source, whereby there is
no influence on the measuring signal / accuracy by the sensor line
resistance / conduit length. Of course, on customer's request, we also
supply the conventional PT100 .
The humidity sensor is structured as a planar
multi-layer sensor and is equipped with a complex software temperature
compensation.
The primary pressure absorber of the air pressure
sensor is based on a silicon absolute pressure sensor item, whose
function is based on the piezo-resistive effect. It is measured against a
vacuum as the reference. It has an internal active temperature
compensation for a wide temperature range. This is achieved by an
integrated signal processor that realizes an extensive correction of the
course of temperature.
The sensor is supplied in a sturdy and impact-resistant plastic casing.
Fields of application
