Introduction
XGZP170 is a piezoresistive pressure sensor that was designed for extremely space sensitive application where the sensing element is to be integral to the OEM products. The core is a silicon piezoresistive pressure sensing die that is designed and fabricated by MEMS technology. The pressure sensing die is composed of a springy diaphragm and four resistors integrated in the diaphragm. Four piezo-resistors build up a Wheatstone bridge structure. When the springy diaphragm is pressured, Wheatstone bridge produces a linear voltage signal(mV) that is proportional to input pressure.
With standard SOP8 package, It is easy for users to install by surface mounting or welding.
With good repeatability, linearity, stability and sensibility, XGZP170 is very facile for users to calibrate output, thermal drift and make temperature compensation by using exterior operational amplifier or integrated circuit.
The pressure medium other than dry air or non-corrosive gas can’t be used directly. It is highly prohibited to choke the side of pressure diaphragm during actual application.
