3.2 Operating principle
3.2.1 Calculating the pressure
Devices with metallic process isolating diaphragm
The process pressure deflects the metal process isolating diaphragm of the sensor and a fill
fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The
pressure-dependent change in the bridge output voltage is measured and evaluated.
