Piezoresistive silicon chip employed
Perfect long term stability
MEMS technology
Cost effective
X19 OEM Pressure Sensor is a standard and economic pressure sensor applied in clean air pressure measurement. A high sensitivity piezoresistive silicon pressure chip is employed in the transducer. Without oil filling, this kind of sensor has a very good temperature performance. The air measured should be no-aggressive, as air will contact pressure chip directly.
