Compared to Piezo type, our Capacitive type is High dynamic range and High impedance.
Thus, Our Capacitive type is suitable for CMOS amp.
High dynamic range and High impedance.
-Capacitance change rate: 15%
-Resistance value: 12pF at 20kHZ => 1.3MΩ
Narow dynamic range, Low impedance
-Resistance change rate: <1%
-Resistance Value: 2kΩ
-Stability for temperature change-
Temperature dependance is controlled very well.
There are 2 stabile efeccts; 1) Syllicon Yong's modules, 2) Inflated fill gas inside the pressure face.
Pressure change of fill gas which inside the pressure face enables to adjust temperature coefficient to 0 at standard pressure value.
Sensor element twist has almost no impact when pressure measuring error.
