Features
The pressure sensors of series DS-KE-D-A are ceramic measuring
cells in thick lm technology for measurement absolute pressure in li-
quids and gases.
As opposed to the ceramic relative pressure sensors DS-KE-D-R the
back of the DS-KE-D-A sensors is evacuated and sealed. The sensors
measure against vacuum.
In addition to being easily cleaned it is another advantage of the ab-
solute pressure sensors that the output signal is independent of the
ambient pressure.
Because the material is a ceramic (Al
2O3), the sensor has an outstan-
ding stability against aggressive and corrosive media.
The delivery spectrum covers the entire pressure range of 1...50 bar FS
with 6 variants for different measuring ranges.
The sensor is made up in the form of a full wheatstone bridge. The
output signal is a pressure dependent differential voltage, that can be
directly processed further with an instrument amplier or an ASIC.
A printed circuit board, matching with the sensor, is available which
gives out an processed and calibrated voltage output of 0...10 V or
current output of 4...20 mA.
Typical areas of application are in the eld of pneumatics, hydraulics
and in industrial applications.
