KKD34-701 capacitive ceramic pressure sensor for extremely low measurement ranges

PEWATRON: This new capacitive pressure sensor handles measurements in the range of 0 - 60 mbar and can be trimmed electronically to 0 - 12 mbar. In addition to this measurement range, it is also possible to make corrections to account for effects arising during assembly by means of an integrated interface. Parameterisation is accomplished with a Windows-compatible, menu-driven kit. The largest range – both absolute and relative measurements are possible – is 0 - 20 bar, and this can be reduced to <10:1.

Various voltage and current output signals can be selected. The KKD34-701 has a diameter of 34 mm and can optionally be ordered with Ex partial approvals according to IBExU 08 ATEX 1062 U Zone 0:ll 1G Ex la llC T4. The standard membrane is 96% Al2O3 and can also be delivered at 99.9% for oxygen applications up to 1 mbar, for instance. Depending on the temperature or other requirements, the sensors are available with various O-rings. Thanks to its robust properties, this sensor is well suited for hydrostatic level measurements and for aggressive media such as acids and alkaline solutions.
