Pressure
The process pressure causes the metal process isolating diaphragm of the sensor to deflect.
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.
Advantages:
• Can be used for high process pressures
• High long-term stability
• High overload resistance
• Secondary containment for enhanced integrity
• Significantly reduced thermal effect e.g. compared to diaphragm seal systems with
capillaries
