1.Introduction

Based on MEMS technology and SOP, DIP, COB packages etc., MEMS series pressure sensors are designed for pressure measurement of non-corrosive pure gases. Our MEMS pressure sensor features as below:




2.MEMS Measurement Principle

The core part of MEMS pressure sensor is a piezoresistive pressure sensing die processed by MEMS technology. The pressure sensing die is composed of a springy diaphragm and four resistors integrated in the diaphragm. Four piezo-resistors form a Wheatstone bridge structure. 

When the springy diaphragm is pressured, Wheatstone bridge will output linear proportional voltage signal with the pressure on. Without pressure changes, there is no output thus consumes few power.
