MEMS Pressure Sensor

MEMS Measurement Principle

The core part of the 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 into the diaphragm. Four piezo-resistors form a Wheatstone bridge structure.

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

MEMS Pressure Sensor Construction

Introduction

MEMS pressure sensor integrates pressure sensing element and digital conditioning chip, compensating the drift, sensitivity, linearity parameters digitally. Relying on the voltage power supply, this pressure sensor outputs a standard voltage signal which is calibrated and compensated. It is suitable for the pressure measurement of non-corrosive pure gases.

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:
