Page 17: Product Description
Product description 3 Product description 3.1 Function The gauge has a capacitive measuring element with a ceramic diaphragm. The pressure deflects the ceramic diaphragm. The gauge detects the deflection of the diaphragm as a change in the capacitance. The electronics convert the capacitance change to an output signal (DC). The output signal is linear with the pressure to be measured. -
