Features
In the field of automotive technology, laundry
dryers, house hold appliances and also in the area
of industrial applications, always sensors are
required which can provide precise measured
value for the entire lifecycle of the product without
the need for re-calibration.
Moreover, the price restrictions are so stiff for such
high volume applications that only fully automatic
mountable sensors stand a chance in the market.
The KFS140 SMD model fulfils this requirement
especialybecause of its proven high performance
polymer and the surface mountable SMD-model.
The sensor can certainly offer a better signal to
noise ratio than monolithic integrated sensors and
are also characterised by excellent long term
stability in continuous operation under rough
conditions.
Due to further miniaturisation, the sensors of the
MSMD series are almost at the limit of technical
feasibility in the range of SMD type humidity
sensors. At present, it represents the smallest
discrete humidity sensor world wide with an
undoubted price performance ratio.
