Thinst to know about absolute pressure or gauge pressure measurement
What does absolute pressure mean?
When it comes to pressure measurement technology, we differentiate between different measuring ranges such as absolute pressure, relative pressure and differential pressure:
If you want to measure the absolute pressure, 0 bar is used as the reference point. This would correspond to the pressure in an absolute vacuum, which of course would only be theoretically achievable. The starting point of the measurement is accordingly at 0 bar, abs. With an absolute pressure sensor, I can now, for example, determine the ambient pressure.
How to measure with an absolute pressure sensor?
With our capacitive ceramic absolute pressure sensors, the reference vacuum (6 X 10 -6 mbar) that is generated during the manufacturing process is retained in the sensor. In relation to the vacuum, this enables permanently stable and accurate pressure measurements.
What does relative pressure mean? How to measure it?
The existing ambient pressure forms the basis for measuring the relative pressure. Accordingly, the values are e.g. dependent on the barometric pressure or the altitude of the measuring point, because the air pressure is lower the higher the measuring point is.
How to measure with a relative pressure sensor?
With gauge pressure sensors, the rear of the process isolating diaphragm is vented. The sensor thus measures the overpressure relative to the prevailing atmospheric pressure.
How does Ceracore – pur ceramic capacitive pressure sensor work?
The Ceracore sensor is based on the capacitive measuring principle. The internally metallized membrane and the base body form the components of a plate capacitor. If the sensor is subjected to pressure, the distance between the membrane and the base changes. This leads to a change in capacitance. This change is converted by the evaluation electronics into a linearized and temperature-compensated output signal. The capacitive ceramic measuring technology offers you a number of advantages for measuring absolute pressure or gauge pressure.

The capacitive ceramic measuring technology offers you a number of advantages for measuring absolute pressure or gauge pressure.
Our ceramic pressure measuring cell works on the basis of the capacitive measuring principle. Membrane and base form the components of a plate capacitor. If the sensor is subjected to pressure, the membrane flexes. This reduces the electrode gap and changes the capacitance of the capacitor. Evaluation electronics convert this change into an electrical output signal.
How can a ceramic pressure cell be individualized?
We build a ceramic pressure measuring cell step by step: Please use our MySensor configurator. There you can enter information about the sensor type, the desired measuring range, the output signal and the required connections, as well as selecting the additional equipment. After you have configured your individual sensor or the appropriate ceramic pressure measuring cell, we will work out a final pressure sensor or pressure transducer for you based on your information.
