Learn how different types of pressure sensors use electric signals and digital technology to measure pressure.
The most important element of the ceramic capacitive technology is the ceramic (Al2O3) measuring cell. After assembly, the ceramic cell element resembles a plate capacitor with a reference electrode and a measuring electrode placed 0.01 mm apart.
The capacitance is inversely proportional to the distance between the electrodes. As a medium applies force, the distance changes by a small value and the capacitance changes proportionately. This signal is then converted into pressure by a microprocessor.

Strain gauges are attached to the stainless steel measuring cell. Pressure of the medium on the measuring cell causes deflection of the strain gauge, which creates a change in resistance. Tension (positive strain) increases resistance and compression (negative strain) decreases resistance. The change in resistance is proportional to the pressure applied.
