Features
The pressure sensors of series DS-KE-R are ceramic measuring cells
in thick lm technology for measurement of static and dynamic relative
pressure in liquids and gases. Typical areas of application are in the
eld of pneumatics, hydraulics and in industrial applications.
Because the material is a ceramic (Al2O3), the sensor has an outstan-
ding stability against aggressive and corrosive media.
The delivery spectrum covers the entire pressure range of 1.6...600 bar
FS with 14 variants for different measuring ranges. The outer dimensi-
ons of all the types are maintained same so that they can be tted in the
same mechanical housing construction.
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.
The sensor is temperature compensated, hence in most of the appli-
cations, the circuit design efforts are reduced to only simple zero point
and gain setting.
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.
