Features
Temperature is one of the most frequently measured physical parame-
ters. For price sensitive mass applications, fully integrated semicon-
ductor sensors are available which have a limited temperature range
of approx. –50 ... +150 °C. In industrial applications, platinum tempe-
rature sensors are very common, which offer a large measuring range
of –100 ... +500 °C, but are more complex to evaluate because the
non-linear behaviour of PTC has to be corrected. Our innovative tem-
perature sensor module with ASIC unites both the worlds: As sensor, a
high quality platinum resistance is used. The ASIC as subsystem with
exible signal processing performs the job of capturing, linearization
and calibration of the sensor raw value till delivering of rened and
processed output signal, which is made available as binary value over
the I²C-Bus or alternatively as voltage signal 0 ... 5 V.
The module offers an optimum price performance ratio. The platinum
temperature sensor is interchangeable, guarantees a high measuring
accuracy, drift stability, environment resistance as well as an outstan
-
ding long-term stability. The ASIC provides the temperature measured
value as a calibrated signal over the appropriate analog or digital inter
-
face with high resolution, which makes simple integration possible into
customized products. The calibrated and standardized output signal gu
-
arantees simplest integration of the subsystem in the development pha-
se and makes shortest time to market product developments possible.
