Pressure transducer UC2 Measuring Principle:A capacitive ceramic sensor element is at the core of the UC2 transducer.
Its Al2O3 basic material is ceramic that is highly resistant against many aggressive gases and liquids. Two cylindrical ceramic components (diaphragm and meter body) are bonded to form a high-strength, hermetically sealed pressure sensor element. With absolute pressure sensors, the vacuum of 3.0 x 10-6 mbar created in the production process between the process isolating diaphragm and the meter body remains permanently. This permits pressure measurements relative to the vacuum. With gauge pressure sensors, the back of the process isolating diaphragm is vented, i.e. this sensor measures the gauge pressure relative to the atmospheric pressure.
Electrically, the sensor element represents a plate capacitor whose capacitance change is the dimension for the pressure change. The capacitive measuring process satisfies the highest requirements concerning resolution and reproducibility. Together with the hysteresis-free behavior of the material Al O , it is the basis for the excellent specifications of the transducer. In addition, the sensor element is a dry measuring cell, i.e. there is no separating diaphragm or filling fluid which could influence the measurement. A further advantage of the capacitive ceramic sensor is its high overload resistance.After removal of the overload, the process isolating diaphragm returns to the initial position without any damage or hysteresis.
